[PYTHON IMAGE-SIG] PIL Feature Summary
Thu, 30 May 1996 00:46:13 +0200
(hello? is there anybody out there?)
I've just uploaded a "feature summary" to the web site, but since it
isn't that much text, I post it here as well.
The 0.1b2 release has been delayed until next week in order to improve
the support for 8-bit displays under Windows. This includes adaptive
palette generation, fast inverse palette mapping, and floyd-steinberg
error diffusion (in other words, decent "RGB" to "P" conversion). And
I couldn't resist adding a few more file formats in the process...
If you wish to try it out, the PYD sneak release works fine on 15- and
Comments are welcomed. Would be fun with at least some traffic on
this list, wouldn't it?

Here's a summary of the current features in the Python Imaging Library
(0.1b1). Things that have been added in the forthcoming 0.1b2 relese
are also described.
* Unix: known to run on Linux, Digital Unix (OSF/1), SGI, Solaris, and
SunOS 4. Requires an ANSI C compiler to build (gcc works fine).
* Windows: runs on 95 and NT. A prebuilt PYD for Mark Hammond's PythonWin
is available (0.1b2).
* Bilevel, greyscale, palette, true colour (RGB), colour separation
* Copy, cut, paste operations.
* Flip, transpose, resize, rotate, and arbitrary affine transforms.
* Transparency operations.
* Channel and point operations.
* Colour transforms, including matrix operations and quantization to
predefined palettes (0.1b2).
* Image enhancement, including convolution filters.
* Full (Open/Load/Save): BMP, JPEG, PPM, TIFF.
* Read only (Open/Load): CUR (0.1b2), DCX, EPS (with ghostscript), GBR,
GD, GIF, ICO (0.1b2), PhotoCD (0.1b2), PCX, TGA, SGI, Sun Raster, XBM.
* Identify only (Open): EPS, FLC, FLI, MPEG, MSP, PNG.
Uses the IJG JPEG library to load and save JPEG files. All other
formats are supported by the standard distribution.
* Tk PhotoImage support for Tkinter.
* Windows NT: GUI independent DIB support (0.1b2). This has been tested
with PythonWin only.
* Identify, convert, print images.
* View images (Tkinter).
* Documentation (PostScript only).
* Postscript printing.
* Graphics support (points, lines, rectangles, text).
* X BDF font support (0.1b2)
* Interface to Jack Jansen's IMG library.
