|
||||
+ 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.
