*** 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:
https://bitbucket.org/effbot/pil-2009-raclette/commits/all
(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 have been replaced 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 premultiplied 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 strength (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.
