[Image-SIG] PIL 0.3b2 is now available
Sun, 19 Jul 1998 16:57:40 +0100
The Python Imaging Library (PIL) adds image processing capabilities
to your Python interpreter. This library provides extensive file format
support, an efficient internal representation, and fairly powerful
image processing capabilities.
This is the second (and hopefully the last) beta release for PIL 0.3.
The source kit has been built and tested on Windows 95 and NT, as
well as on Linux (Redhat 4.2) and Digital Unix. It should build out of
the box on most mainstream Unix versions.

Here are the changes from the previous beta:
+ 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
+ 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
+ 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")
+ 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" (!)
