sizes).
"image2py" (NEW) Convert a single image to a py
"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.
