*** Changes from release 1.1.6 to 1.1.7 ***
|
|
|
|
This section may not be fully complete. For changes since this file
|
|
was last updated, see the repository revision history:
|
|
|
|
http://bitbucket.org/effbot/pil-2009-raclette/changesets/
|
|
|
|
(1.1.7 final)
|
|
|
|
+ Set GIF loop info property to the number of iterations if a NETSCAPE
|
|
loop extension is present, instead of always setting it to 1 (from
|
|
Valentino Volonghi).
|
|
|
|
(1.1.7c1 released)
|
|
|
|
+ Improved PNG compression (from Alexey Borzenkov).
|
|
|
|
+ Read interlaced PNG files (from Conrado Porto Lopes Gouvêa)
|
|
|
|
+ Added various TGA improvements from Alexey Borzenkov, including
|
|
support for specifying image orientation.
|
|
|
|
+ Bumped block threshold to 16 megabytes, made size estimation a bit
|
|
more accurate. This speeds up allocation of large images.
|
|
|
|
+ Fixed rounding error in ImagingDrawWideLine.
|
|
|
|
"gormish" writes: ImagingDrawWideLine() in Draw.c has a bug in every
|
|
version I've seen, which leads to different width lines depending on
|
|
the order of the points in the line. This is especially bad at some
|
|
angles where a 'width=2' line can completely disappear.
|
|
|
|
+ Added support for RGBA mode to the SGI module (based on code by
|
|
Karsten Hiddemann).
|
|
|
|
+ Handle repeated IPTC tags (adapted from a patch by Eric Bruning).
|
|
|
|
Eric writes: According to the specification, some IPTC tags can be
|
|
repeated, e.g., tag 2:25 (keywords). PIL 1.1.6 only retained the last
|
|
instance of that tag. Below is a patch to store all tags. If there are
|
|
multiple tag instances, they are stored in a (python) list. Single tag
|
|
instances remain as strings.
|
|
|
|
+ Fixed potential crash in ImageFilter for small target images
|
|
(reported by Zac Burns and Daniel Fetchinson).
|
|
|
|
+ Use BMP instead of JPEG as temporary show format on Mac OS X.
|
|
|
|
+ Fixed putpixel/new for I;16 with colors > 255.
|
|
|
|
+ Added integer power support to ImagingMath.
|
|
|
|
+ Added limited support for I;16L mode (explicit little endian).
|
|
|
|
+ Moved WMF support into Image.core; enable WMF rendering by default
|
|
if renderer is available.
|
|
|
|
+ Mark the ARG plugin as obsolete.
|
|
|
|
+ Added version query mechanism to ImageCms and ImageFont, for
|
|
debugging.
|
|
|
|
+ Added (experimental) ImageCms function for fetching the ICC profile
|
|
for the current display (currently Windows only).
|
|
|
|
Added HWND/HDC support to ImageCms.get_display_profile().
|
|
|
|
+ Added WMF renderer (Windows only).
|
|
|
|
+ Added ImagePointHandler and ImageTransformHandler mixins; made
|
|
ImageCmsTransform work with im.point.
|
|
|
|
+ Fixed potential endless loop in the XVThumbnail reader (from Nikolai
|
|
Ugelvik).
|
|
|
|
+ Added Kevin Cazabon's pyCMS package.
|
|
|
|
The C code has been moved to _imagingcms.c, the Python interface
|
|
module is installed as PIL.ImageCMS.
|
|
|
|
Added support for in-memory ICC profiles.
|
|
|
|
Unified buildTransform and buildTransformFromOpenProfiles.
|
|
|
|
The profile can now be either a filename, a profile object, or a
|
|
file-like object containing an in-memory profile.
|
|
|
|
Additional fixes from Florian Böch:
|
|
|
|
Very nice - it just needs LCMS flags support so we can use black
|
|
point compensation and softproofing :) See attached patches. They
|
|
also fix a naming issue which could cause confusion - display
|
|
profile (ImageCms wording) actually means proof profile (lcms
|
|
wording), so I changed variable names and docstrings where
|
|
applicable. Patches are tested under Python 2.6.
|
|
|
|
+ Improved support for layer names in PSD files (from Sylvain Baubeau)
|
|
|
|
Sylvain writes: I needed to be able to retrieve the names of the
|
|
layers in a PSD files. But PsdImagePlugin.py didn't do the job so I
|
|
wrote this very small patch.
|
|
|
|
+ Improved RGBA support for ImageTk for 8.4 and newer (from Con
|
|
Radchenko).
|
|
|
|
This replaces the slow run-length based encoding model with true
|
|
compositing at the Tk level.
|
|
|
|
+ Added support for 16- and 32-bit images to McIdas loader.
|
|
|
|
Based on file samples and stand-alone reader code provided by Craig
|
|
Swank.
|
|
|
|
+ Added ImagePalette support to putpalette.
|
|
|
|
+ Fixed problem with incremental parsing of PNG files.
|
|
|
|
+ Make selftest.py report non-zero status on failure (from Mark
|
|
Sienkiewicz)
|
|
|
|
+ Add big endian save support and multipage infrastructure to the TIFF
|
|
writer (from Sebastian Haase).
|
|
|
|
+ Handle files with GPS IFD but no basic EXIF IFD (reported by Kurt
|
|
Schwehr).
|
|
|
|
+ Added zTXT support (from Andrew Kuchling via Lowell Alleman).
|
|
|
|
+ Fixed potential infinite loop bug in ImageFont (from Guilherme Polo).
|
|
|
|
+ Added sample ICC profiles (from Kevin Cazabon)
|
|
|
|
+ Fixed array interface for I, F, and RGBA/RGBX images.
|
|
|
|
+ Added Chroma subsampling support for JPEG (from Justin Huff).
|
|
|
|
Justin writes: Attached is a patch (against PIL 1.1.6) to provide
|
|
control over the chroma subsampling done by the JPEG encoder. This
|
|
is often useful for reducing compression artifacts around edges of
|
|
clipart and text.
|
|
|
|
+ Added USM/Gaussian Blur code from Kevin Cazabon.
|
|
|
|
+ Fixed bug w. uninitialized image data when cropping outside the
|
|
source image.
|
|
|
|
+ Use ImageShow to implement the Image.show method.
|
|
|
|
Most notably, this picks the 'display' utility when available. It
|
|
also allows application code to register new display utilities via
|
|
the ImageShow registry.
|
|
|
|
+ Release the GIL in the PNG compressor (from Michael van Tellingen).
|
|
|
|
+ Revised JPEG CMYK handling.
|
|
|
|
Always assume Adobe behaviour, both when reading and writing (based on
|
|
a patch by Kevin Cazabon, and test data by Tim V. and Charlie Clark, and
|
|
additional debugging by Michael van Tellingen).
|
|
|
|
+ Support for preserving ICC profiles (by Florian Böch via Tim Hatch).
|
|
|
|
Florian writes:
|
|
|
|
It's a beta, so still needs some testing, but should allow you to:
|
|
- retain embedded ICC profiles when saving from/to JPEG, PNG, TIFF.
|
|
Existing code doesn't need to be changed.
|
|
- access embedded profiles in JPEG, PNG, PSD, TIFF.
|
|
|
|
It also includes patches for TIFF to retain IPTC, Photoshop and XMP
|
|
metadata when saving as TIFF again, read/write TIFF resolution
|
|
information correctly, and to correct inverted CMYK JPEG files.
|
|
|
|
+ Fixed potential memory leak in median cut quantizer (from Evgeny Salmin).
|
|
|
|
+ Fixed OverflowError when reading upside-down BMP images.
|
|
|
|
+ Added resolution save option for PDF files.
|
|
|
|
Andreas Kostyrka writes: I've included a patched PdfImagePlugin.py
|
|
based on 1.1.6 as included in Ubuntu, that supports a "resolution"
|
|
save option. Not great, but it makes the PDF saving more useful by
|
|
allowing PDFs that are not exactly 72dpi.
|
|
|
|
+ Look for Tcl/Tk include files in version-specific include directory
|
|
(from Encolpe Degoute).
|
|
|
|
+ Fixed grayscale rounding error in ImageColor.getcolor (from Tim
|
|
Hatch).
|
|
|
|
+ Fixed calculation of mean value in ImageEnhance.Contrast (reported
|
|
by "roop" and Scott David Daniels).
|
|
|
|
+ Fixed truetype positioning when first character has a negative left
|
|
bearing (from Ned Batchelder):
|
|
|
|
Ned writes: In PIL 1.1.6, ImageDraw.text will position the string
|
|
incorrectly if the first character has a negative left bearing. To
|
|
see the problem, show a string like "///" in an italic font. The
|
|
first slash will be clipped at the left, and the string will be
|
|
mis-positioned.
|
|
|
|
+ Fixed resolution unit bug in tiff reader/writer (based on code by
|
|
Florian Höch, Gary Bloom, and others).
|
|
|
|
+ Added simple transparency support for RGB images (reported by
|
|
Sebastian Spaeth).
|
|
|
|
+ Added support for Unicode filenames in ImageFont.truetype (from Donn
|
|
Ingle).
|
|
|
|
+ Fixed potential crash in ImageFont.getname method (from Donn Ingle).
|
|
|
|
+ Fixed encoding issue in PIL/WalImageFile (from Santiago M. Mola).
|
|
|
|
*** Changes from release 1.1.5 to 1.1.6 ***
|
|
|
|
(1.1.6 released)
|
|
|
|
+ Fixed some 64-bit compatibility warnings for Python 2.5.
|
|
|
|
+ Added threading support for the Sane driver (from Abel Deuring).
|
|
|
|
(1.1.6b2 released)
|
|
|
|
+ Added experimental "floodfill" function to the ImageDraw module
|
|
(based on code by Eric Raymond).
|
|
|
|
+ The default arguments for "frombuffer" doesn't match "fromstring"
|
|
and the documentation; this is a bug, and will most likely be fixed
|
|
in a future version. In this release, PIL prints a warning message
|
|
instead. To silence the warning, change any calls of the form
|
|
"frombuffer(mode, size, data)" to
|
|
|
|
frombuffer(mode, size, data, "raw", mode, 0, 1)
|
|
|
|
+ Added "fromarray" function, which takes an object implementing the
|
|
NumPy array interface and creates a PIL Image from it. (from Travis
|
|
Oliphant).
|
|
|
|
+ Added NumPy array interface support (__array_interface__) to the
|
|
Image class (based on code by Travis Oliphant).
|
|
|
|
This allows you to easily convert between PIL image memories and
|
|
NumPy arrays:
|
|
|
|
import numpy, Image
|
|
|
|
im = Image.open('lena.jpg')
|
|
|
|
a = numpy.asarray(im) # a is readonly
|
|
|
|
im = Image.fromarray(a)
|
|
|
|
+ Fixed CMYK polarity for JPEG images, by treating all images as
|
|
"Adobe CMYK" images. (thanks to Cesare Leonardi and Kevin Cazabon
|
|
for samples, debugging, and patches).
|
|
|
|
(1.1.6b1 released)
|
|
|
|
+ Added 'expand' option to the Image 'rotate' method. If true, the
|
|
output image is made large enough to hold the entire rotated image.
|
|
|
|
+ Changed the ImageDraw 'line' method to always draw the last pixel in
|
|
a polyline, independent of line angle.
|
|
|
|
+ Fixed bearing calculation and clipping in the ImageFont truetype
|
|
renderer; this could lead to clipped text, or crashes in the low-
|
|
level _imagingft module. (based on input from Adam Twardoch and
|
|
others).
|
|
|
|
+ Added ImageQt wrapper module, for converting PIL Image objects to
|
|
QImage objects in an efficient way.
|
|
|
|
+ Fixed 'getmodebands' to return the number of bands also for "PA"
|
|
and "LA" modes. Added 'getmodebandnames' helper that return the
|
|
band names.
|
|
|
|
(1.1.6a2 released)
|
|
|
|
+ Added float/double support to the TIFF loader (from Russell
|
|
Nelson).
|
|
|
|
+ Fixed broken use of realloc() in path.c (from Jan Matejek)
|
|
|
|
+ Added save support for Spider images (from William Baxter).
|
|
|
|
+ Fixed broken 'paste' and 'resize' operations in pildriver
|
|
(from Bill Janssen).
|
|
|
|
+ Added support for duplex scanning to the Sane interface (Abel
|
|
Deuring).
|
|
|
|
(1.1.6a1 released)
|
|
|
|
+ Fixed a memory leak in "convert(mode)", when converting from
|
|
L to P.
|
|
|
|
+ Added pixel access object. The "load" method now returns a
|
|
access object that can be used to directly get and set pixel
|
|
values, using ordinary [x, y] notation:
|
|
|
|
pixel = im.load()
|
|
v = pixel[x, y]
|
|
pixel[x, y] = v
|
|
|
|
If you're accessing more than a few pixels, this is a lot
|
|
faster than using getpixel/putpixel.
|
|
|
|
+ Fixed building on Cygwin (from Miki Tebeka).
|
|
|
|
+ Fixed "point(callable)" on unloaded images (reported by Håkan
|
|
Karlsson).
|
|
|
|
+ Fixed size bug in ImageWin.ImageWindow constructor (from Victor
|
|
Reijs)
|
|
|
|
+ Fixed ImageMath float() and int() operations for Python 2.4
|
|
(reported by Don Rozenberg).
|
|
|
|
+ Fixed "RuntimeError: encoder error -8 in tostring" problem for
|
|
wide "RGB", "I", and "F" images.
|
|
|
|
+ Fixed line width calculation.
|
|
|
|
(1.1.6a0 released)
|
|
|
|
+ Fixed byte order issue in Image.paste(ink) (from Ka-Ping Yee).
|
|
|
|
+ Fixed off-by-0.5 errors in the ANTIALIAS code (based on input
|
|
from Douglas Bagnall).
|
|
|
|
+ Added buffer interface support to the Path constructor. If
|
|
a buffer is provided, it is assumed to contain a flat array
|
|
of float coordinates (e.g. array.array('f', seq)).
|
|
|
|
+ Added new ImageMath module.
|
|
|
|
+ Fixed ImageOps.equalize when used with a small number of distinct
|
|
values (reported by David Kirtley).
|
|
|
|
+ Fixed potential integer division in PSDraw.image (from Eric Etheridge).
|
|
|
|
*** Changes from release 1.1 to 1.1.5 ***
|
|
|
|
(1.1.5c2 and 1.1.5 final released)
|
|
|
|
+ Added experimental PERSPECTIVE transform method (from Jeff Breiden-
|
|
bach).
|
|
|
|
(1.1.5c1 released)
|
|
|
|
+ Make sure "thumbnail" never generates zero-wide or zero-high images
|
|
(reported by Gene Skonicki)
|
|
|
|
+ Fixed a "getcolors" bug that could result in a zero count for some
|
|
colors (reported by Richard Oudkerk).
|
|
|
|
+ Changed default "convert" palette to avoid "rounding errors" when
|
|
round-tripping white source pixels (reported by Henryk Gerlach and
|
|
Jeff Epler).
|
|
|
|
(1.1.5b3 released)
|
|
|
|
+ Don't crash in "quantize" method if the number of colors requested
|
|
is larger than 256. This release raises a ValueError exception;
|
|
future versions may return a mode "RGB" image instead (reported
|
|
by Richard Oudkerk).
|
|
|
|
+ Added WBMP read/write support (based on code by Duncan Booth).
|
|
|
|
(1.1.5b2 released)
|
|
|
|
+ Added DPI read/write support to the PNG codec. The decoder sets
|
|
the info["dpi"] attribute for PNG files with appropriate resolution
|
|
settings. The encoder uses the "dpi" option (based on code by Niki
|
|
Spahiev).
|
|
|
|
+ Added limited support for "point" mappings from mode "I" to mode "L".
|
|
Only 16-bit values are supported (other values are clipped), the lookup
|
|
table must contain exactly 65536 entries, and the mode argument must be
|
|
set to "L".
|
|
|
|
+ Added support for Mac OS X icns files (based on code by Bob Ippolito).
|
|
|
|
+ Added "ModeFilter" support to the ImageFilter module.
|
|
|
|
+ Added support for Spider images (from William Baxter). See the
|
|
comments in PIL/SpiderImagePlugin.py for more information on this
|
|
format.
|
|
|
|
(1.1.5b1 released)
|
|
|
|
+ Added new Sane release (from Ralph Heinkel). See the Sane/README
|
|
and Sane/CHANGES files for more information.
|
|
|
|
+ Added experimental PngInfo chunk container to the PngImageFile
|
|
module. This can be used to add arbitrary chunks to a PNG file.
|
|
Create a PngInfo instance, use "add" or "add_text" to add chunks,
|
|
and pass the instance as the "pnginfo" option when saving the
|
|
file.
|
|
|
|
+ Added "getpalette" method. This returns the palette as a list,
|
|
or None if the image has no palette. To modify the palette, use
|
|
"getpalette" to fetch the current palette, modify the list, and
|
|
put it back using "putpalette".
|
|
|
|
+ Added optional flattening to the ImagePath "tolist" method.
|
|
tolist() or tolist(0) returns a list of 2-tuples, as before.
|
|
tolist(1) returns a flattened list instead.
|
|
|
|
(1.1.5a5 released)
|
|
|
|
+ Fixed BILINEAR/BICUBIC/ANTIALIAS filtering for mode "LA".
|
|
|
|
+ Added "getcolors()" method. This is similar to the existing histo-
|
|
gram method, but looks at color values instead of individual layers,
|
|
and returns an unsorted list of (count, color) tuples.
|
|
|
|
By default, the method returns None if finds more than 256 colors.
|
|
If you need to look for more colors, you can pass in a limit (this
|
|
is used to allocate internal tables, so you probably don't want to
|
|
pass in too large values).
|
|
|
|
+ Build improvements: Fixed building under AIX, improved detection of
|
|
FreeType2 and Mac OS X framework libraries, and more. Many thanks
|
|
to everyone who helped test the new "setup.py" script!
|
|
|
|
(1.1.5a4 released)
|
|
|
|
+ The "save" method now looks for a file format driver before
|
|
creating the file.
|
|
|
|
+ Don't use antialiased truetype fonts when drawing in mode "P", "I",
|
|
and "F" images.
|
|
|
|
+ Rewrote the "setup.py" file. The new version scans for available
|
|
support libraries, and configures both the libImaging core library
|
|
and the bindings in one step.
|
|
|
|
To use specific versions of the libraries, edit the ROOT variables
|
|
in the setup.py file.
|
|
|
|
+ Removed threaded "show" viewer; use the old "show" implementation
|
|
instead (Windows).
|
|
|
|
+ Added deprecation warnings to Image.offset, ImageDraw.setink, and
|
|
ImageDraw.setfill.
|
|
|
|
+ Added width option to ImageDraw.line(). The current implementation
|
|
works best for straight lines; it does not support line joins, so
|
|
polylines won't look good.
|
|
|
|
+ ImageDraw.Draw is now a factory function instead of a class. If
|
|
you need to create custom draw classes, inherit from the ImageDraw
|
|
class. All other code should use the factory function.
|
|
|
|
+ Fixed loading of certain PCX files (problem reported by Greg
|
|
Hamilton, who also provided samples).
|
|
|
|
+ Changed _imagingft.c to require FreeType 2.1 or newer. The
|
|
module can still be built with earlier versions; see comments
|
|
in _imagingft.c for details.
|
|
|
|
(1.1.5a3 released)
|
|
|
|
+ Added 'getim' method, which returns a PyCObject wrapping an
|
|
Imaging pointer. The description string is set to IMAGING_MAGIC.
|
|
See Imaging.h for pointer and string declarations.
|
|
|
|
+ Fixed reading of TIFF JPEG images (problem reported by Ulrik
|
|
Svensson).
|
|
|
|
+ Made ImageColor work under Python 1.5.2
|
|
|
|
+ Fixed division by zero "equalize" on very small images (from
|
|
Douglas Bagnall).
|
|
|
|
(1.1.5a2 released)
|
|
|
|
+ The "paste" method now supports the alternative "paste(im, mask)"
|
|
syntax (in this case, the box defaults to im's bounding box).
|
|
|
|
+ The "ImageFile.Parser" class now works also for PNG files with
|
|
more than one IDAT block.
|
|
|
|
+ Added DPI read/write to the TIFF codec, and fixed writing of
|
|
rational values. The decoder sets the info["dpi"] attribute
|
|
for TIFF files with appropriate resolution settings. The
|
|
encoder uses the "dpi" option.
|
|
|
|
+ Disable interlacing for small (or narrow) GIF images, to
|
|
work around what appears to be a hard-to-find bug in PIL's
|
|
GIF encoder.
|
|
|
|
+ Fixed writing of mode "P" PDF images. Made mode "1" PDF
|
|
images smaller.
|
|
|
|
+ Made the XBM reader a bit more robust; the file may now start
|
|
with a few whitespace characters.
|
|
|
|
+ Added support for enhanced metafiles to the WMF driver. The
|
|
separate PILWMF kit lets you render both placeable WMF files
|
|
and EMF files as raster images. See
|
|
|
|
http://effbot.org/downloads#pilwmf
|
|
|
|
(1.1.5a1 released)
|
|
|
|
+ Replaced broken WMF driver with a WMF stub plugin (see below).
|
|
|
|
+ Fixed writing of mode "1", "L", and "CMYK" PDF images (based on
|
|
input from Nicholas Riley and others).
|
|
|
|
+ Fixed adaptive palette conversion for zero-width or zero-height
|
|
images (from Chris Cogdon)
|
|
|
|
+ Fixed reading of PNG images from QuickTime 6 (from Paul Pharr)
|
|
|
|
+ Added support for StubImageFile plugins, including stub plugins
|
|
for BUFR, FITS, GRIB, and HDF5 files. A stub plugin can identify
|
|
a given file format, but relies on application code to open and
|
|
save files in that format.
|
|
|
|
+ Added optional "encoding" argument to the ImageFont.truetype
|
|
factory. This argument can be used to specify non-Unicode character
|
|
maps for fonts that support that. For example, to draw text using
|
|
the Microsoft Symbol font, use:
|
|
|
|
font = ImageFont.truetype("symbol.ttf", 16, encoding="symb")
|
|
draw.text((0, 0), unichr(0xF000 + 0xAA))
|
|
|
|
(note that the symbol font uses characters in the 0xF000-0xF0FF
|
|
range)
|
|
|
|
Common encodings are "unic" (Unicode), "symb" (Microsoft Symbol),
|
|
"ADOB" (Adobe Standard), "ADBE" (Adobe Expert), and "armn" (Apple
|
|
Roman). See the FreeType documentation for more information.
|
|
|
|
+ Made "putalpha" a bit more robust; you can now attach an alpha
|
|
layer to a plain "L" or "RGB" image, and you can also specify
|
|
constant alphas instead of alpha layers (using integers or colour
|
|
names).
|
|
|
|
+ Added experimental "LA" mode support.
|
|
|
|
An "LA" image is an "L" image with an attached transparency layer.
|
|
Note that support for "LA" is not complete; some operations may
|
|
fail or produce unexpected results.
|
|
|
|
+ Added "RankFilter", "MinFilter", "MedianFilter", and "MaxFilter"
|
|
classes to the ImageFilter module.
|
|
|
|
+ Improved support for applications using multiple threads; PIL
|
|
now releases the global interpreter lock for many CPU-intensive
|
|
operations (based on work by Kevin Cazabon).
|
|
|
|
+ Ignore Unicode characters in the PCF loader (from Andres Polit)
|
|
|
|
+ Fixed typo in OleFileIO.loadfat, which could affect loading of
|
|
FlashPix and Image Composer images (Daniel Haertle)
|
|
|
|
+ Fixed building on platforms that have Freetype but don't have
|
|
Tcl/Tk (Jack Jansen, Luciano Nocera, Piet van Oostrum and others)
|
|
|
|
+ Added EXIF GPSInfo read support for JPEG files. To extract
|
|
GPSInfo information, open the file, extract the exif dictionary,
|
|
and check for the key 0x8825 (GPSInfo). If present, it contains
|
|
a dictionary mapping GPS keys to GPS values. For a list of keys,
|
|
see the EXIF specification.
|
|
|
|
The "ExifTags" module contains a GPSTAGS dictionary mapping GPS
|
|
tags to tag names.
|
|
|
|
+ Added DPI read support to the PCX and DCX codecs (info["dpi"]).
|
|
|
|
+ The "show" methods now uses a built-in image viewer on Windows.
|
|
This viewer creates an instance of the ImageWindow class (see
|
|
below) and keeps it running in a separate thread. NOTE: This
|
|
was disabled in 1.1.5a4.
|
|
|
|
+ Added experimental "Window" and "ImageWindow" classes to the
|
|
ImageWin module. These classes allow you to create a WCK-style
|
|
toplevel window, and use it to display raster data.
|
|
|
|
+ Fixed some Python 1.5.2 issues (to build under 1.5.2, use the
|
|
Makefile.pre.in/Setup.in approach)
|
|
|
|
+ Added support for the TIFF FillOrder tag. PIL can read mode "1",
|
|
"L", "P" and "RGB" images with non-standard FillOrder (based on
|
|
input from Jeff Breidenbach).
|
|
|
|
(1.1.4 final released)
|
|
|
|
+ Fixed ImageTk build problem on Unix.
|
|
|
|
(1.1.4b2 released)
|
|
|
|
+ Improved building on Mac OS X (from Jack Jansen).
|
|
|
|
+ Improved building on Windows with MinGW (from Klamer Shutte).
|
|
|
|
+ If no font is specified, ImageDraw now uses the embedded default
|
|
font. Use the "load" or "truetype" methods to load a real font.
|
|
|
|
+ Added embedded default font to the ImageFont module (currently
|
|
an 8-pixel Courier font, taken from the X window distribution).
|
|
|
|
(1.1.4b1 released)
|
|
|
|
+ Added experimental EXIF support for JPEG files. To extract EXIF
|
|
information from a JPEG file, open the file as usual, and call the
|
|
"_getexif" method. If successful, this method returns a dictionary
|
|
mapping EXIF TIFF tags to values. If the file does not contain EXIF
|
|
data, the "_getexif" method returns None.
|
|
|
|
The "ExifTags" module contains a dictionary mapping tags to tag
|
|
names.
|
|
|
|
This interface will most likely change in future versions.
|
|
|
|
+ Fixed a bug when using the "transparency" option with the GIF
|
|
writer.
|
|
|
|
+ Added limited support for "bitfield compression" in BMP files
|
|
and DIB buffers, for 15-bit, 16-bit, and 32-bit images. This
|
|
also fixes a problem with ImageGrab module when copying screen-
|
|
dumps from the clipboard on 15/16/32-bit displays.
|
|
|
|
+ Added experimental WAL (Quake 2 textures) loader. To use this
|
|
loader, import WalImageFile and call the "open" method in that
|
|
module.
|
|
|
|
(1.1.4a4 released)
|
|
|
|
+ Added updated SANE driver (Andrew Kuchling, Abel Deuring)
|
|
|
|
+ Use Python's "mmap" module on non-Windows platforms to read some
|
|
uncompressed formats using memory mapping. Also added a "frombuffer"
|
|
function that allows you to access the contents of an existing string
|
|
or buffer object as if it were an image object.
|
|
|
|
+ Fixed a memory leak that could appear when processing mode "P"
|
|
images (from Pier Paolo Glave)
|
|
|
|
+ Ignore Unicode characters in the BDF loader (from Graham Dumpleton)
|
|
|
|
(1.1.4a3 released; windows only)
|
|
|
|
+ Added experimental RGBA-on-RGB drawing support. To use RGBA
|
|
colours on an RGB image, pass "RGBA" as the second string to
|
|
the ImageDraw.Draw constructor.
|
|
|
|
+ Added support for non-ASCII strings (Latin-1) and Unicode
|
|
to the truetype font renderer.
|
|
|
|
+ The ImageWin "Dib" object can now be constructed directly from
|
|
an image object.
|
|
|
|
+ The ImageWin module now allows you use window handles as well
|
|
as device contexts. To use a window handle, wrap the handle in
|
|
an ImageWin.HWND object, and pass in this object instead of the
|
|
device context.
|
|
|
|
(1.1.4a2 released)
|
|
|
|
+ Improved support for 16-bit unsigned integer images (mode "I;16").
|
|
This includes TIFF reader support, and support for "getextrema"
|
|
and "point" (from Klamer Shutte).
|
|
|
|
+ Made the BdfFontFile reader a bit more robust (from Kevin Cazabon
|
|
and Dmitry Vasiliev)
|
|
|
|
+ Changed TIFF writer to always write Compression tag, even when
|
|
using the default compression (from Greg Couch).
|
|
|
|
+ Added "show" support for Mac OS X (from Dan Wolfe).
|
|
|
|
+ Added clipboard support to the "ImageGrab" module (Windows only).
|
|
The "grabclipboard" function returns an Image object, a list of
|
|
filenames (not in 1.1.4), or None if neither was found.
|
|
|
|
(1.1.4a1 released)
|
|
|
|
+ Improved support for drawing RGB data in palette images. You can
|
|
now use RGB tuples or colour names (see below) when drawing in a
|
|
mode "P" image. The drawing layer automatically assigns color
|
|
indexes, as long as you don't use more than 256 unique colours.
|
|
|
|
+ Moved self test from MiniTest/test.py to ./selftest.py.
|
|
|
|
+ Added support for CSS3-style color strings to most places that
|
|
accept colour codes/tuples. This includes the "ImageDraw" module,
|
|
the Image "new" function, and the Image "paste" method.
|
|
|
|
Colour strings can use one of the following formats: "#f00",
|
|
"#ff0000", "rgb(255,0,0)", "rgb(100%,0%,0%)", "hsl(0, 100%, 50%)",
|
|
or "red" (most X11-style colour names are supported). See the
|
|
documentation for the "ImageColor" module for more information.
|
|
|
|
+ Fixed DCX decoder (based on input from Larry Bates)
|
|
|
|
+ Added "IptcImagePlugin.getiptcinfo" helper to extract IPTC/NAA
|
|
newsphoto properties from JPEG, TIFF, or IPTC files.
|
|
|
|
+ Support for TrueType/OpenType fonts has been added to
|
|
the standard distribution. You need the freetype 2.0
|
|
library.
|
|
|
|
+ Made the PCX reader a bit more robust when reading 2-bit
|
|
and 4-bit PCX images with odd image sizes.
|
|
|
|
+ Added "Kernel" class to the ImageFilter module. This class
|
|
allows you to filter images with user-defined 3x3 and 5x5
|
|
convolution kernels.
|
|
|
|
+ Added "putdata" support for mode "I", "F" and "RGB".
|
|
|
|
+ The GIF writer now supports the transparency option (from
|
|
Denis Benoit).
|
|
|
|
+ A HTML version of the module documentation is now shipped
|
|
with the source code distribution. You'll find the files in
|
|
the Doc subdirectory.
|
|
|
|
+ Added support for Palm pixmaps (from Bill Janssen). This
|
|
change was listed for 1.1.3, but the "PalmImagePlugin" driver
|
|
didn't make it into the distribution.
|
|
|
|
+ Improved decoder error messages.
|
|
|
|
(1.1.3 final released)
|
|
|
|
+ Made setup.py look for old versions of zlib. For some back-
|
|
ground, see: http://www.gzip.org/zlib/advisory-2002-03-11.txt
|
|
|
|
(1.1.3c2 released)
|
|
|
|
+ Added setup.py file (tested on Unix and Windows). You still
|
|
need to build libImaging/imaging.lib in the traditional way,
|
|
but the setup.py script takes care of the rest.
|
|
|
|
The old Setup.in/Makefile.pre.in build method is still
|
|
supported.
|
|
|
|
+ Fixed segmentation violation in ANTIALIAS filter (an internal
|
|
buffer wasn't properly allocated).
|
|
|
|
(1.1.3c1 released)
|
|
|
|
+ Added ANTIALIAS downsampling filter for high-quality "resize"
|
|
and "thumbnail" operations. Also added filter option to the
|
|
"thumbnail" operation; the default value is NEAREST, but this
|
|
will most likely change in future versions.
|
|
|
|
+ Fixed plugin loader to be more robust if the __file__
|
|
variable isn't set.
|
|
|
|
+ Added seek/tell support (for layers) to the PhotoShop
|
|
loader. Layer 0 is the main image.
|
|
|
|
+ Added new (but experimental) "ImageOps" module, which provides
|
|
shortcuts for commonly used operations on entire images.
|
|
|
|
+ Don't mess up when loading PNG images if the decoder leaves
|
|
data in the output buffer. This could cause internal errors
|
|
on some PNG images, with some versions of ZLIB. (Bug report
|
|
and patch provided by Bernhard Herzog.)
|
|
|
|
+ Don't mess up on Unicode filenames.
|
|
|
|
+ Don't mess up when drawing on big endian platforms.
|
|
|
|
+ Made the TIFF loader a bit more robust; it can now read some
|
|
more slightly broken TIFF files (based on input from Ted Wright,
|
|
Bob Klimek, and D. Alan Stewart)
|
|
|
|
+ Added OS/2 EMX build files (from Andrew MacIntyre)
|
|
|
|
+ Change "ImageFont" to reject image files if they don't have the
|
|
right mode. Older versions could leak memory for "P" images.
|
|
(Bug reported by Markus Gritsch).
|
|
|
|
+ Renamed some internal functions to avoid potential build
|
|
problem on Mac OS X.
|
|
|
|
+ Added DL_EXPORT where relevant (for Cygwin, based on input
|
|
from Robert Yodlowski)
|
|
|
|
+ (re)moved bogus __init__ call in BdfFontFile (bug spotted
|
|
by Fred Clare)
|
|
|
|
+ Added "ImageGrab" support (Windows only)
|
|
|
|
+ Added support for XBM hotspots (based on code contributed by
|
|
Bernhard Herzog).
|
|
|
|
+ Added write support for more TIFF tags, namely the Artist,
|
|
Copyright, DateTime, ResolutionUnit, Software, XResolution and
|
|
YResolution tags (from Greg Couch)
|
|
|
|
+ Added TransposedFont wrapper to ImageFont module
|
|
|
|
+ Added "optimize" flag to GIF encoder. If optimize is present
|
|
and non-zero, PIL will work harder to create a small file.
|
|
|
|
+ Raise "EOFError" (not IndexError) when reading beyond the
|
|
end of a TIFF sequence.
|
|
|
|
+ Support rewind ("seek(0)") for GIF and TIFF sequences.
|
|
|
|
+ Load grayscale GIF images as mode "L"
|
|
|
|
+ Added DPI read/write support to the JPEG codec. The decoder
|
|
sets the info["dpi"] attribute for JPEG files with JFIF dpi
|
|
settings. The encoder uses the "dpi" option:
|
|
|
|
im = Image.open("file.jpg")
|
|
dpi = im.info["dpi"] # raises KeyError if DPI not known
|
|
im.save("out.jpg", dpi=dpi)
|
|
|
|
Note that PIL doesn't always preserve the "info" attribute
|
|
for normal image operations.
|
|
|
|
(1.1.2c1 and 1.1.2 final released)
|
|
|
|
+ Adapted to Python 2.1. Among other things, all uses of the
|
|
"regex" module has been repleased with "re".
|
|
|
|
+ Fixed attribute error when reading large PNG files (this bug
|
|
was introduced in maintenance code released after the 1.1.1
|
|
release)
|
|
|
|
+ Ignore non-string objects in sys.path
|
|
|
|
+ Fixed Image.transform(EXTENT) for negative xoffsets
|
|
|
|
+ Fixed loading of image plugins if PIL is installed as a package.
|
|
(The plugin loader now always looks in the directory where the
|
|
Image.py module itself is found, even if that directory isn't on
|
|
the standard search path)
|
|
|
|
+ The Png plugin has been added to the list of preloaded standard
|
|
formats
|
|
|
|
+ Fixed bitmap/text drawing in fill mode.
|
|
|
|
+ Fixed "getextrema" to work also for multiband images.
|
|
|
|
+ Added transparency support for L and P images to the PNG codec.
|
|
|
|
+ Improved support for read-only images. The "load" method now
|
|
sets the "readonly" attribute for memory-mapped images. Operations
|
|
that modifies an image in place (such as "paste" and drawing operations)
|
|
creates an in-memory copy of the image, if necessary. (before this
|
|
change, any attempt to modify a memory-mapped image resulted in a
|
|
core dump...)
|
|
|
|
+ Added special cases for lists everywhere PIL expects a sequence.
|
|
This should speed up things like "putdata" and drawing operations.
|
|
|
|
+ The Image.offset method is deprecated. Use the ImageChops.offset
|
|
function instead.
|
|
|
|
+ Changed ImageChops operators to copy palette and info dictionary
|
|
from the first image argument.
|
|
|
|
(1.1.1 released)
|
|
|
|
+ Additional fixes for Python 1.6/2.0, including TIFF "save" bug.
|
|
|
|
+ Changed "init" to properly load plugins when PIL is used as a
|
|
package.
|
|
|
|
+ Fixed broken "show" method (on Unix)
|
|
|
|
*** Changes from release 1.0 to 1.1 ***
|
|
|
|
+ Adapted to Python 1.6 ("append" and other method changes)
|
|
|
|
+ Fixed Image.paste when pasting with solid colour and matte
|
|
layers ("L" or "RGBA" masks) (bug reported by Robert Kern)
|
|
|
|
+ To make it easier to distribute prebuilt versions of PIL,
|
|
the tkinit binding stuff has been moved to a separate
|
|
extension module, named "_imagingtk".
|
|
|
|
*** Changes from release 0.3b2 to 1.0 final ***
|
|
|
|
+ If there's no 16-bit integer (like on a Cray T3E), set
|
|
INT16 to the smallest integer available. Most of the
|
|
library works just fine anyway (from Bill Crutchfield)
|
|
|
|
+ Tweaks to make drawing work on big-endian platforms.
|
|
|
|
(1.0c2 released)
|
|
|
|
+ If PIL is built with the WITH_TKINTER flag, ImageTk can
|
|
automatically hook into a standard Tkinter build. You
|
|
no longer need to build your own Tkinter to use the
|
|
ImageTk module.
|
|
|
|
The old way still works, though. For more information,
|
|
see Tk/install.txt.
|
|
|
|
+ Some tweaks to ImageTk to support multiple Tk interpreters
|
|
(from Greg Couch).
|
|
|
|
+ ImageFont "load_path" now scans directory mentioned in .pth
|
|
files (from Richard Jones).
|
|
|
|
(1.0c1 released)
|
|
|
|
+ The TIFF plugin has been rewritten. The new plugin fully
|
|
supports all major PIL image modes (including F and I).
|
|
|
|
+ The ImageFile module now includes a Parser class, which can
|
|
be used to incrementally decode an image file (while down-
|
|
loading it from the net, for example). See the handbook for
|
|
details.
|
|
|
|
+ "show" now converts non-standard modes to "L" or "RGB" (as
|
|
appropriate), rather than writing weird things to disk for
|
|
"xv" to choke upon. (bug reported by Les Schaffer).
|
|
|
|
(1.0b2 released)
|
|
|
|
+ Major speedups for rotate, transform(EXTENT), and transform(AFFINE)
|
|
when using nearest neighbour resampling.
|
|
|
|
+ Modified ImageDraw to be compatible with the Arrow graphics
|
|
interface. See the handbook for details.
|
|
|
|
+ PIL now automatically loads file codecs when used as a package
|
|
(from The Dragon De Monsyne). Also included an __init__.py file
|
|
in the standard distribution.
|
|
|
|
+ The GIF encoder has been modified to produce much smaller files.
|
|
|
|
PIL now uses a run-length encoding method to encode GIF files.
|
|
On a random selection of GIF images grabbed from the web, this
|
|
version makes the images about twice as large as the original
|
|
LZW files, where the earlier version made them over 5 times
|
|
larger. YMMV, of course.
|
|
|
|
+ Added PCX write support (works with "1", "P", "L", and "RGB")
|
|
|
|
+ Added "bitmap" and "textsize" methods to ImageDraw.
|
|
|
|
+ Improved font rendering code. Fixed a bug or two, and moved
|
|
most of the time critical stuff to C.
|
|
|
|
+ Removed "bdf2pil.py". Use "pilfont.py" instead!
|
|
|
|
+ Improved 16-bit support (still experimental, though).
|
|
|
|
The following methods now support "I;16" and "I;16B" images:
|
|
"getpixel", "copy", "convert" (to and from mode "I"), "resize",
|
|
"rotate", and "transform" with nearest neighbour filters, and
|
|
"save" using the IM format. The "new" and "open" functions
|
|
also work as expected. On Windows, 16-bit files are memory
|
|
mapped.
|
|
|
|
NOTE: ALL other operations are still UNDEFINED on 16-bit images.
|
|
|
|
+ The "paste" method now supports constant sources.
|
|
|
|
Just pass a colour value (a number or a tuple, depending on
|
|
the target image mode) instead of the source image.
|
|
|
|
This was in fact implemented in an inefficient way in
|
|
earlier versions (the "paste" method generated a temporary
|
|
source image if you passed it a colour instead of an image).
|
|
In this version, this is handled on the C level instead.
|
|
|
|
+ Added experimental "RGBa" mode support.
|
|
|
|
An "RGBa" image is an RGBA image where the colour components
|
|
have have been premultipled with the alpha value. PIL allows
|
|
you to convert an RGBA image to an RGBa image, and to paste
|
|
RGBa images on top of RGB images. Since this saves a bunch
|
|
of multiplications and shifts, it is typically about twice
|
|
as fast an ordinary RGBA paste.
|
|
|
|
+ Eliminated extra conversion step when pasting "RGBA" or "RGBa"
|
|
images on top of "RGB" images.
|
|
|
|
+ Fixed Image.BICUBIC resampling for "RGB" images.
|
|
|
|
+ Fixed PCX image file handler to properly read 8-bit PCX
|
|
files (bug introduced in 1.0b1, reported by Bernhard
|
|
Herzog)
|
|
|
|
+ Fixed PSDraw "image" method to restore the coordinate
|
|
system.
|
|
|
|
+ Fixed "blend" problem when applied to images that was
|
|
not already loaded (reported by Edward C. Jones)
|
|
|
|
+ Fixed -f option to "pilconvert.py" (from Anthony Baxter)
|
|
|
|
(1.0b1 released)
|
|
|
|
+ Added Toby J. Sargeant's quantization package. To enable
|
|
quantization, use the "palette" option to "convert":
|
|
|
|
imOut = im.convert("P", palette=Image.ADAPTIVE)
|
|
|
|
This can be used with "L", "P", and "RGB" images. In this
|
|
version, dithering cannot be used with adaptive palettes.
|
|
|
|
Note: ADAPTIVE currently maps to median cut quantization
|
|
with 256 colours. The quantization package also contains
|
|
a maximum coverage quantizer, which will be supported by
|
|
future versions of PIL.
|
|
|
|
+ Added Eric S. Raymond's "pildriver" image calculator to the
|
|
distribution. See the docstring for more information.
|
|
|
|
+ The "offset" method no longer dumps core if given positive
|
|
offsets (from Charles Waldman).
|
|
|
|
+ Fixed a resource leak that could cause ImageWin to run out of
|
|
GDI resources (from Roger Burnham).
|
|
|
|
+ Added "arc", "chord", and "pieslice" methods to ImageDraw (inspired
|
|
by code contributed by Richard Jones).
|
|
|
|
+ Added experimental 16-bit support, via modes "I;16" (little endian
|
|
data) and "I;16B" (big endian). Only a few methods properly support
|
|
such images (see above).
|
|
|
|
+ Added XV thumbnail file handler (from Gene Cash).
|
|
|
|
+ Fixed BMP image file handler to handle palette images with small
|
|
palettes (from Rob Hooft).
|
|
|
|
+ Fixed Sun raster file handler for palette images (from Charles
|
|
Waldman).
|
|
|
|
+ Improved various internal error messages.
|
|
|
|
+ Fixed Path constructor to handle arbitrary sequence objects. This
|
|
also affects the ImageDraw class (from Richard Jones).
|
|
|
|
+ Fixed a bug in JpegDecode that caused PIL to report "decoder error
|
|
-2" for some progressive JPEG files (reported by Magnus Källström,
|
|
who also provided samples).
|
|
|
|
+ Fixed a bug in JpegImagePlugin that caused PIL to hang when loading
|
|
JPEG files using 16-bit quantization tables.
|
|
|
|
+ The Image "transform" method now supports Image.QUAD transforms.
|
|
The data argument is an 8-tuple giving the upper left, lower
|
|
left, lower right, and upper right corner of the source quadri-
|
|
lateral. Also added Image.MESH transform which takes a list
|
|
of quadrilaterals.
|
|
|
|
+ The Image "resize", "rotate", and "transform" methods now support
|
|
Image.BILINEAR (2x2) and Image.BICUBIC (4x4) resampling filters.
|
|
Filters can be used with all transform methods.
|
|
|
|
+ The ImageDraw "rectangle" method now includes both the right
|
|
and the bottom edges when drawing filled rectangles.
|
|
|
|
+ The TGA decoder now works properly for runlength encoded images
|
|
which have more than one byte per pixel.
|
|
|
|
+ "getbands" on an YCbCr image now returns ("Y", "Cb", "Cr")
|
|
|
|
+ Some file drivers didn't handle the optional "modify" argument
|
|
to the load method. This resulted in exceptions when you used
|
|
"paste" (and other methods that modify an image in place) on a
|
|
newly opened file.
|
|
|
|
*** Changes from release 0.2 (b5) to 0.3 (b2) ***
|
|
|
|
(0.3b2 released)
|
|
|
|
The test suite includes 825 individual tests.
|
|
|
|
+ An Image "getbands" method has been added. It returns a tuple
|
|
containing the individual band names for this image. To figure
|
|
out how many bands an image has, use "len(im.getbands())".
|
|
|
|
+ An Image "putpixel" method has been added.
|
|
|
|
+ The Image "point" method can now be used to convert "L" images
|
|
to any other format, via a lookup table. That table should
|
|
contain 256 values for each band in the output image.
|
|
|
|
+ Some file drivers (including FLI/FLC, GIF, and IM) accidently
|
|
overwrote the offset method with an internal attribute. All
|
|
drivers have been updated to use private attributes where
|
|
possible.
|
|
|
|
+ The Image "histogram" method now works for "I" and "F" images.
|
|
For these modes, PIL divides the range between the min and
|
|
max values used in the image into 256 bins. You can also
|
|
pass in your own min and max values via the "extrema" option:
|
|
|
|
h = im.histogram(extrema=(0, 255))
|
|
|
|
+ An Image "getextrema" method has been added. It returns the
|
|
min and max values used in the image. In this release, this
|
|
works for single band images only.
|
|
|
|
+ Changed the PNG driver to load and save mode "I" images as
|
|
16-bit images. When saving, values outside the range 0..65535
|
|
are clipped.
|
|
|
|
+ Fixed ImageFont.py to work with the new "pilfont" compiler.
|
|
|
|
+ Added JPEG "save" and "draft" support for mode "YCbCr" images.
|
|
Note that if you save an "YCbCr" image as a JPEG file and read
|
|
it back, it is read as an RGB file. To get around this, you
|
|
can use the "draft" method:
|
|
|
|
im = Image.open("color.jpg")
|
|
im.draft("YCbCr", im.size)
|
|
|
|
+ Read "RGBA" TGA images. Also fixed the orientation bug; all
|
|
images should now come out the right way.
|
|
|
|
+ Changed mode name (and internal representation) from "YCrCb"
|
|
to "YCbCr" (!)
|
|
*** WARNING: MAY BREAK EXISTING CODE ***
|
|
|
|
(0.3b1 released)
|
|
|
|
The test suite includes 750 individual tests.
|
|
|
|
+ The "pilfont" package is now included in the standard PIL
|
|
distribution. The pilfont utility can be used to convert
|
|
X BDF and PCF raster font files to a format understood by
|
|
the ImageFont module.
|
|
|
|
+ GIF files are now interlaced by default. To write a
|
|
non-interlaced file, pass interlace=0 to the "save"
|
|
method.
|
|
|
|
+ The default string format has changed for the "fromstring"
|
|
and "tostring" methods.
|
|
*** WARNING: MAY BREAK EXISTING CODE ***
|
|
|
|
NOTE: If no extra arguments are given, the first line in
|
|
the string buffer is the top line of the image, instead of
|
|
the bottom line. For RGB images, the string now contains
|
|
3 bytes per pixel instead of 4. These changes were made
|
|
to make the methods compatible with the "fromstring"
|
|
factory function.
|
|
|
|
To get the old behaviour, use the following syntax:
|
|
|
|
data = im.tostring("raw", "RGBX", 0, -1)
|
|
im.fromstring(data, "raw", "RGBX", 0, -1)
|
|
|
|
+ "new" no longer gives a MemoryError if the width or height
|
|
is zero (this only happened on platforms where malloc(0)
|
|
or calloc(0) returns NULL).
|
|
|
|
+ "new" now adds a default palette object to "P" images.
|
|
|
|
+ You can now convert directly between all modes supported by
|
|
PIL. When converting colour images to "P", PIL defaults to
|
|
a "web" palette and dithering. When converting greyscale
|
|
images to "1", PIL uses a thresholding and dithering.
|
|
|
|
+ Added a "dither" option to "convert". By default, "convert"
|
|
uses floyd-steinberg error diffusion for "P" and "1" targets,
|
|
so this option is only used to *disable* dithering. Allowed
|
|
values are NONE (no dithering) or FLOYDSTEINBERG (default).
|
|
|
|
imOut = im.convert("P", dither=Image.NONE)
|
|
|
|
+ Added a full set of "I" decoders. You can use "fromstring"
|
|
(and file decoders) to read any standard integer type as an
|
|
"I" image.
|
|
|
|
+ Added some support for "YCbCr" images (creation, conversion
|
|
from/to "L" and "RGB", IM YCC load/save)
|
|
|
|
+ "getpixel" now works properly with fractional coordinates.
|
|
|
|
+ ImageDraw "setink" now works with "I", "F", "RGB", "RGBA",
|
|
"RGBX", "CMYK", and "YCbCr" images.
|
|
|
|
+ ImImagePlugin no longer attaches palettes to "RGB" images.
|
|
|
|
+ Various minor fixes.
|
|
|
|
(0.3a4 released)
|
|
|
|
+ Added experimental IPTC/NAA support.
|
|
|
|
+ Eliminated AttributeError exceptions after "crop" (from
|
|
Skip Montanaro)
|
|
|
|
+ Reads some uncompressed formats via memory mapping (this
|
|
is currently supported on Win32 only)
|
|
|
|
+ Fixed some last minute glitches in the last alpha release
|
|
(Types instead of types in Image.py, version numbers, etc.)
|
|
|
|
+ Eliminated some more bogus compiler warnings.
|
|
|
|
+ Various fixes to make PIL compile and run smoother on Macs
|
|
(from Jack Jansen).
|
|
|
|
+ Fixed "fromstring" and "tostring" for mode "I" images.
|
|
|
|
(0.3a3 released)
|
|
|
|
The test suite includes 530 individual tests.
|
|
|
|
+ Eliminated unexpected side-effect in "paste" with matte. "paste"
|
|
now works properly also if compiled with "gcc".
|
|
|
|
+ Adapted to Python 1.5 (build issues only)
|
|
|
|
+ Fixed the ImageDraw "point" method to draw also the last
|
|
point (!).
|
|
|
|
+ Added "I" and "RGBX" support to Image.new.
|
|
|
|
+ The plugin path is now properly prepended to the module search
|
|
path when a plugin module is imported.
|
|
|
|
+ Added "draw" method to the ImageWin.Dib class. This is used by
|
|
Topaz to print images on Windows printers.
|
|
|
|
+ "convert" now supports conversions from "P" to "1" and "F".
|
|
|
|
+ "paste" can now take a colour instead of an image as the first argument.
|
|
The colour must match the colour argument given to the new function, and
|
|
match the mode of the target image.
|
|
|
|
+ Fixed "paste" to allow a mask also for mode "F" images.
|
|
|
|
+ The BMP driver now saves mode "1" images. When loading images, the mode
|
|
is set to "L" for 8-bit files with greyscale palettes, and to "P" for
|
|
other 8-bit files.
|
|
|
|
+ The IM driver now reads and saves "1" images (file modes "0 1" or "L 1").
|
|
|
|
+ The JPEG and GIF drivers now saves "1" images. For JPEG, the image
|
|
is saved as 8-bit greyscale (it will load as mode "L"). For GIF, the
|
|
image will be loaded as a "P" image.
|
|
|
|
+ Fixed a potential buffer overrun in the GIF encoder.
|
|
|
|
(0.3a2 released)
|
|
|
|
The test suite includes 400 individual tests.
|
|
|
|
+ Improvements to the test suite revealed a number of minor bugs, which
|
|
are all fixed. Note that crop/paste, 32-bit ImageDraw, and ImageFont
|
|
are still weak spots in this release.
|
|
|
|
+ Added "putpalette" method to the Image class. You can use this
|
|
to add or modify the palette for "P" and "L" images. If a palette
|
|
is added to an "L" image, it is automatically converted to a "P"
|
|
image.
|
|
|
|
+ Fixed ImageDraw to properly handle 32-bit image memories
|
|
("RGB", "RGBA", "CMYK", "F")
|
|
|
|
+ Fixed "fromstring" and "tostring" not to mess up the mode attribute
|
|
in default mode.
|
|
|
|
+ Changed ImPlatform.h to work on CRAY's (don't have one at home, so I
|
|
haven't tried it). The previous version assumed that either "short"
|
|
or "int" were 16-bit wide. PIL still won't compile on platforms where
|
|
neither "short", "int" nor "long" are 32-bit wide.
|
|
|
|
+ Added file= and data= keyword arguments to PhotoImage and BitmapImage.
|
|
This allows you to use them as drop-in replacements for the corre-
|
|
sponding Tkinter classes.
|
|
|
|
+ Removed bogus references to the crack coder (ImagingCrack).
|
|
|
|
(0.3a1 released)
|
|
|
|
+ Make sure image is loaded in "tostring".
|
|
|
|
+ Added floating point packer (native 32-bit floats only).
|
|
|
|
*** Changes from release 0.1b1 to 0.2 (b5) ***
|
|
|
|
+ Modified "fromstring" and "tostring" methods to use file codecs.
|
|
Also added "fromstring" factory method to create an image directly
|
|
from data in a string.
|
|
|
|
+ Added support for 32-bit floating point images (mode "F"). You
|
|
can convert between "L" and "F" images, and apply a subset of the
|
|
available image processing methods on the "F" image. You can also
|
|
read virtually any data format into a floating point image memory;
|
|
see the section on "Decoding Floating Point Data" in the handbook
|
|
for more information.
|
|
|
|
(0.2b5 released; on windows only)
|
|
|
|
+ Fixed the tobitmap() method to work properly for small bitmaps.
|
|
|
|
+ Added RMS and standard deviation to the ImageStat.Stat class. Also
|
|
modified the constructor to take an optional feature mask, and also
|
|
to accept either an image or a list containing the histogram data.
|
|
|
|
+ The BitmapImage code in ImageTk can now use a special bitmap
|
|
decoder, which has to be patched into Tk. See the "Tk/pilbitmap.txt"
|
|
file for details. If not installed, bitmaps are transferred to Tk as
|
|
XBM strings.
|
|
|
|
+ The PhotoImage code in ImageTk now uses a Tcl command ("PyImagingPaste")
|
|
instead of a special image type. This gives somewhat better performance,
|
|
and also allows PIL to support transparency.
|
|
*** WARNING: TKAPPINIT MUST BE MODIFIED ***
|
|
|
|
+ ImageTk now honours the alpha layer in RGBA images. Only fully
|
|
transparent pixels are made transparent (that is, the alpha layer
|
|
is treated as a mask). To treat the alpha laters as a matte, you
|
|
must paste the image on the background before handing it over to
|
|
ImageTk.
|
|
|
|
+ Added McIdas reader (supports 8-bit images only).
|
|
|
|
+ PIL now preloads drivers for BMP, GIF, JPEG, PPM, and TIFF. As
|
|
long as you only load and save these formats, you don't have to
|
|
wait for a full scan for drivers. To force scanning, call the
|
|
Image.init() function.
|
|
|
|
+ The "seek" and "tell" methods are now always available, also for
|
|
single-frame images.
|
|
|
|
+ Added optional mask argument to histogram method. The mask may
|
|
be an "1" or "L" image with the same size as the original image.
|
|
Only pixels where the mask is non-zero are included in the
|
|
histogram.
|
|
|
|
+ The "paste" method now allows you to specify only the lower left
|
|
corner (a 2-tuple), instead of the full region (a 4-tuple).
|
|
|
|
+ Reverted to old plugin scanning model; now scans all directory
|
|
names in the path when looking for plugins.
|
|
|
|
+ Added PIXAR raster support. Only uncompressed ("dumped") RGB
|
|
images can currently be read (based on information provided
|
|
by Greg Coats).
|
|
|
|
+ Added FlashPix (FPX) read support. Reads all pixel formats, but
|
|
only the highest resolution is read, and the viewing transform is
|
|
currently ignored.
|
|
|
|
+ Made PNG encoding somewhat more efficient in "optimize" mode; a
|
|
bug in 0.2b4 didn't enable all predictor filters when optimized
|
|
storage were requested.
|
|
|
|
+ Added Microsoft Image Composer (MIC) read support. When opened,
|
|
the first sprite in the file is loaded. You can use the seek method
|
|
to load additional sprites from the file.
|
|
|
|
+ Properly reads "P" and "CMYK" PSD images.
|
|
|
|
+ "pilconvert" no longer optimizes by default; use the -o option to
|
|
make the file as small as possible (at the expense of speed); use
|
|
the -q option to set the quality when compressing to JPEG.
|
|
|
|
+ Fixed "crop" not to drop the palette for "P" images.
|
|
|
|
+ Added and verified FLC support.
|
|
|
|
+ Paste with "L" or "RGBA" alpha is now several times faster on most
|
|
platforms.
|
|
|
|
+ Changed Image.new() to initialize the image to black, as described
|
|
in the handbook. To get an uninitialized image, use None as the
|
|
colour.
|
|
|
|
+ Fixed the PDF encoder to produce a valid header; Acrobat no longer
|
|
complains when you load PDF images created by PIL.
|
|
|
|
+ PIL only scans fully-qualified directory names in the path when
|
|
looking for plugins.
|
|
*** WARNING: MAY BREAK EXISTING CODE ***
|
|
|
|
+ Faster implementation of "save" used when filename is given,
|
|
or when file object has "fileno" and "flush" methods.
|
|
|
|
+ Don't crash in "crop" if region extends outside the source image.
|
|
|
|
+ Eliminated a massive memory leak in the "save" function.
|
|
|
|
+ The GIF decoder doesn't crash if the code size is set to an illegal
|
|
value. This could happen since another bug didn't handle local
|
|
palettes properly if they didn't have the same size as the
|
|
global palette (not very common).
|
|
|
|
+ Added predictor support (TIFF 6.0 section 14) to the TIFF decoder.
|
|
|
|
+ Fixed palette and padding problems in BMP driver. Now properly
|
|
writes "1", "L", "P" and "RGB" images.
|
|
|
|
+ Fixed getpixel()/getdata() to return correct pixel values.
|
|
|
|
+ Added PSD (PhotoShop) read support. Reads both uncompressed
|
|
and compressed images of most types.
|
|
|
|
+ Added GIF write support (writes "uncompressed" GIF files only,
|
|
due to unresolvable licensing issues). The "gifmaker.py" script
|
|
can be used to create GIF animations.
|
|
|
|
+ Reads 8-bit "L" and "P" TGA images. Also reads 16-bit "RGB"
|
|
images.
|
|
|
|
+ Added FLI read support. This driver has only been tested
|
|
on a few FLI samples.
|
|
|
|
+ Reads 2-bit and 4-bit PCX images.
|
|
|
|
+ Added MSP read and write support. Both version 1 and 2 can be
|
|
read, but only version 1 (uncompressed) files are written.
|
|
|
|
+ Fixed a bug in the FLI/FLC identification code that caused the
|
|
driver to raise an exception when parsing valid FLI/FLC files.
|
|
|
|
+ Improved performance when loading file format plugins, and when
|
|
opening files.
|
|
|
|
+ Added GIF animation support, via the "seek" and "tell" methods.
|
|
You can use "player.py" to play an animated GIF file.
|
|
|
|
+ Removed MNG support, since the spec is changing faster than I
|
|
can change the code. I've added support for the experimental
|
|
ARG format instead. Contact me for more information on this
|
|
format.
|
|
|
|
+ Added keyword options to the "save" method. The following options
|
|
are currently supported:
|
|
|
|
format option description
|
|
--------------------------------------------------------
|
|
JPEG optimize minimize output file at the
|
|
expense of compression speed.
|
|
|
|
JPEG progressive enable progressive output. the
|
|
option value is ignored.
|
|
|
|
JPEG quality set compression quality (1-100).
|
|
the default value is 75.
|
|
|
|
JPEG smooth smooth dithered images. value
|
|
is strengh (1-100). default is
|
|
off (0).
|
|
|
|
PNG optimize minimize output file at the
|
|
expense of compression speed.
|
|
|
|
Expect more options in future releases. Also note that
|
|
file writers silently ignore unknown options.
|
|
|
|
+ Plugged memory leaks in the PNG and TIFF decoders.
|
|
|
|
+ Added PNG write support.
|
|
|
|
+ (internal) RGB unpackers and converters now set the pad byte
|
|
to 255 (full opacity).
|
|
|
|
+ Properly handles the "transparency" property for GIF, PNG
|
|
and XPM files.
|
|
|
|
+ Added a "putalpha" method, allowing you to attach a "1" or "L"
|
|
image as the alpha layer to an "RGBA" image.
|
|
|
|
+ Various improvements to the sample scripts:
|
|
|
|
"pilconvert" Carries out some extra tricks in order to make
|
|
the resulting file as small as possible.
|
|
|
|
"explode" (NEW) Split an image sequence into individual frames.
|
|
|
|
"gifmaker" (NEW) Convert a sequence file into a GIF animation.
|
|
Note that the GIF encoder create "uncompressed" GIF
|
|
files, so animations created by this script are
|
|
rather large (typically 2-5 times the compressed
|
|
sizes).
|
|
|
|
"image2py" (NEW) Convert a single image to a python module. See
|
|
comments in this script for details.
|
|
|
|
"player" If multiple images are given on the command line,
|
|
they are interpreted as frames in a sequence. The
|
|
script assumes that they all have the same size.
|
|
Also note that this script now can play FLI/FLC
|
|
and GIF animations.
|
|
|
|
This player can also execute embedded Python
|
|
animation applets (ARG format only).
|
|
|
|
"viewer" Transparent images ("P" with transparency property,
|
|
and "RGBA") are superimposed on the standard Tk back-
|
|
ground.
|
|
|
|
+ Fixed colour argument to "new". For multilayer images, pass a
|
|
tuple: (Red, Green, Blue), (Red, Green, Blue, Alpha), or (Cyan,
|
|
Magenta, Yellow, Black).
|
|
|
|
+ Added XPM (X pixmap) read support.
|
|
|
|
(0.2b3 released)
|
|
|
|
+ Added MNG (multi-image network graphics) read support. "Ming"
|
|
is a proposed animation standard, based on the PNG file format.
|
|
|
|
You can use the "player" sample script to display some flavours
|
|
of this format. The MNG standard is still under development,
|
|
as is this driver. More information, including sample files,
|
|
can be found at <ftp://swrinde.nde.swri.edu/pub/mng>
|
|
|
|
+ Added a "verify" method to images loaded from file. This method
|
|
scans the file for errors, without actually decoding the image
|
|
data, and raises a suitable exception if it finds any problems.
|
|
Currently implemented for PNG and MNG files only.
|
|
|
|
+ Added support for interlaced GIF images.
|
|
|
|
+ Added PNG read support -- if linked with the ZLIB compression library,
|
|
PIL reads all kinds of PNG images, except interlaced files.
|
|
|
|
+ Improved PNG identification support -- doesn't mess up on unknown
|
|
chunks, identifies all possible PNG modes, and verifies checksum
|
|
on PNG header chunks.
|
|
|
|
+ Added an experimental reader for placable Windows Meta Files (WMF).
|
|
This reader is still very incomplete, but it illustrates how PIL's
|
|
drawing capabilities can be used to render vector and metafile
|
|
formats.
|
|
|
|
+ Added restricted drivers for images from Image Tools (greyscale
|
|
only) and LabEye/IFUNC (common interchange modes only).
|
|
|
|
+ Some minor improvements to the sample scripts provided in the
|
|
"Scripts" directory.
|
|
|
|
+ The test images have been moved to the "Images" directory.
|
|
|
|
(0.2b2 released)
|
|
(0.2b1 released; Windows only)
|
|
|
|
+ Fixed filling of complex polygons. The ImageDraw "line" and
|
|
"polygon" methods also accept Path objects.
|
|
|
|
+ The ImageTk "PhotoImage" object can now be constructed directly
|
|
from an image. You can also pass the object itself to Tkinter,
|
|
instead of using the "image" attribute. Finally, using "paste"
|
|
on a displayed image automatically updates the display.
|
|
|
|
+ The ImageTk "BitmapImage" object allows you to create transparent
|
|
overlays from 1-bit images. You can pass the object itself to
|
|
Tkinter. The constructor takes the same arguments as the Tkinter
|
|
BitmapImage class; use the "foreground" option to set the colour
|
|
of the overlay.
|
|
|
|
+ Added a "putdata" method to the Image class. This can be used to
|
|
load a 1-layer image with data from a sequence object or a string.
|
|
An optional floating point scale and offset can be used to adjust
|
|
the data to fit into the 8-bit pixel range. Also see the "getdata"
|
|
method.
|
|
|
|
+ Added the EXTENT method to the Image "transform" method. This can
|
|
be used to quickly crop, stretch, shrink, or mirror a subregion
|
|
from another image.
|
|
|
|
+ Adapted to Python 1.4.
|
|
|
|
+ Added a project makefile for Visual C++ 4.x. This allows you to
|
|
easily build a dynamically linked version of PIL for Windows 95
|
|
and NT.
|
|
|
|
+ A Tk "booster" patch for Windows is available. It gives dramatic
|
|
performance improvements for some displays. Has been tested with
|
|
Tk 4.2 only, but is likely to work with Tk 4.1 as well. See the Tk
|
|
subdirectory for details.
|
|
|
|
+ You can now save 1-bit images in the XBM format. In addition, the
|
|
Image class now provides a "tobitmap" method which returns a string
|
|
containing an XBM representation of the image. Quite handy to use
|
|
with Tk.
|
|
|
|
+ More conversions, including "RGB" to "1" and more.
|
|
|
|
(0.2a1 released)
|
|
|
|
+ Where earlier versions accepted lists, this version accepts arbitrary
|
|
Python sequences (including strings, in some cases). A few resource
|
|
leaks were plugged in the process.
|
|
|
|
+ The Image "paste" method now allows the box to extend outside
|
|
the target image. The size of the box, the image to be pasted,
|
|
and the optional mask must still match.
|
|
|
|
+ The ImageDraw module now supports filled polygons, outlined and
|
|
filled ellipses, and text. Font support is rudimentary, though.
|
|
|
|
+ The Image "point" method now takes an optional mode argument,
|
|
allowing you to convert the image while translating it. Currently,
|
|
this can only be used to convert "L" or "P" images to "1" images
|
|
(creating thresholded images or "matte" masks).
|
|
|
|
+ An Image "getpixel" method has been added. For single band images,
|
|
it returns the pixel value at a given position as an integer.
|
|
For n-band images, it returns an n-tuple of integers.
|
|
|
|
+ An Image "getdata" method has been added. It returns a sequence
|
|
object representing the image as a 1-dimensional array. Only len()
|
|
and [] can be used with this sequence. This method returns a
|
|
reference to the existing image data, so changes in the image
|
|
will be immediately reflected in the sequence object.
|
|
|
|
+ Fixed alignment problems in the Windows BMP writer.
|
|
|
|
+ If converting an "RGB" image to "RGB" or "L", you can give a second
|
|
argument containing a colour conversion matrix.
|
|
|
|
+ An Image "getbbox" method has been added. It returns the bounding
|
|
box of data in an image, considering the value 0 as background.
|
|
|
|
+ An Image "offset" method has been added. It returns a new image
|
|
where the contents of the image have been offset the given distance
|
|
in X and/or Y direction. Data wraps between edges.
|
|
|
|
+ Saves PDF images. The driver creates a binary PDF 1.1 files, using
|
|
JPEG compression for "L", "RGB", and "CMYK" images, and hex encoding
|
|
(same as for PostScript) for other formats.
|
|
|
|
+ The "paste" method now accepts "1" masks. Zero means transparent,
|
|
any other pixel value means opaque. This is faster than using an
|
|
"L" transparency mask.
|
|
|
|
+ Properly writes EPS files (and properly prints images to postscript
|
|
printers as well).
|
|
|
|
+ Reads 4-bit BMP files, as well as 4 and 8-bit Windows ICO and CUR
|
|
files. Cursor animations are not supported.
|
|
|
|
+ Fixed alignment problems in the Sun raster loader.
|
|
|
|
+ Added "draft" and "thumbnail" methods. The draft method is used
|
|
to optimize loading of JPEG and PCD files, the thumbnail method is
|
|
used to create a thumbnail representation of an image.
|
|
|
|
+ Added Windows display support, via the ImageWin class (see the
|
|
handbook for details).
|
|
|
|
+ Added raster conversion for EPS files. This requires GNU or Aladdin
|
|
Ghostscript, and probably works on UNIX only.
|
|
|
|
+ Reads PhotoCD (PCD) images. The base resolution (768x512) can be
|
|
read from a PhotoCD file.
|
|
|
|
+ Eliminated some compiler warnings. Bindings now compile cleanly in C++
|
|
mode. Note that the Imaging library itself must be compiled in C mode.
|
|
|
|
+ Added "bdf2pil.py", which converts BDF fonts into images with associated
|
|
metrics. This is definitely work in progress. For info, see description
|
|
in script for details.
|
|
|
|
+ Fixed a bug in the "ImageEnhance.py" module.
|
|
|
|
+ Fixed a bug in the netpbm save hack in "GifImagePlugin.py"
|
|
|
|
+ Fixed 90 and 270 degree rotation of rectangular images.
|
|
|
|
+ Properly reads 8-bit TIFF palette-color images.
|
|
|
|
+ Reads plane separated RGB and CMYK TIFF images.
|
|
|
|
+ Added driver debug mode. This is enabled by setting Image.DEBUG
|
|
to a non-zero value. Try the -D option to "pilfile.py" and see what
|
|
happens.
|
|
|
|
+ Don't crash on "atend" constructs in PostScript files.
|
|
|
|
+ Only the Image module imports _imaging directly. Other modules
|
|
should refer to the binding module as "Image.core".
|
|
|
|
*** Changes from release 0.0 to 0.1 (b1) ***
|
|
|
|
+ A handbook is available (distributed separately).
|
|
|
|
+ The coordinate system is changed so that (0,0) is now located
|
|
in the upper left corner. This is in compliancy with ISO 12087
|
|
and 90% of all other image processing and graphics libraries.
|
|
|
|
+ Modes "1" (bilevel) and "P" (palette) have been introduced. Note
|
|
that bilevel images are stored with one byte per pixel.
|
|
|
|
+ The Image "crop" and "paste" methods now accepts None as the
|
|
box argument, to refer to the full image (self, that is).
|
|
|
|
+ The Image "crop" method now works properly.
|
|
|
|
+ The Image "point" method is now available. You can use either a
|
|
lookup table or a function taking one argument.
|
|
|
|
+ The Image join function has been renamed to "merge".
|
|
|
|
+ An Image "composite" function has been added. It is identical
|
|
to copy() followed by paste(mask).
|
|
|
|
+ An Image "eval" function has been added. It is currently identical
|
|
to point(function); that is, only a single image can be processed.
|
|
|
|
+ A set of channel operations has been added. See the "ImageChops"
|
|
module, test_chops.py, and the handbook for details.
|
|
|
|
+ Added the "pilconvert" utility, which converts image files. Note
|
|
that the number of output formats are still quite restricted.
|
|
|
|
+ Added the "pilfile" utility, which quickly identifies image files
|
|
(without loading them, in most cases).
|
|
|
|
+ Added the "pilprint" utility, which prints image files to Postscript
|
|
printers.
|
|
|
|
+ Added a rudimentary version of the "pilview" utility, which is
|
|
simple image viewer based on Tk. Only File/Exit and Image/Next
|
|
works properly.
|
|
|
|
+ An interface to Tk has been added. See "Lib/ImageTk.py" and README
|
|
for details.
|
|
|
|
+ An interface to Jack Jansen's Img library has been added (thanks to
|
|
Jack). This allows you to read images through the Img extensions file
|
|
format handlers. See the file "Lib/ImgExtImagePlugin.py" for details.
|
|
|
|
+ Postscript printing is provided through the PSDraw module. See the
|
|
handbook for details.
