-pngquant is a simple tool with one purpose:  convert 32-bit RGBA PNGs into
-8-bit RGBA-palette PNGs (or fewer than 8 bits, if you want), via quantization
-and either ordered or diffusion (Floyd-Steinberg) dithering.  The fact that
-you can also use it on RGB or even palette images (e.g., to further color-
-reduce them to 16 colors or whatever) is just a nice little bonus.

+The pngquant utility converts 32-bit RGBA PNGs to 8-bit RGBA-palette PNGs (or
+fewer than 8 bits, if you want), via quantization and ordered or diffusion
+(Floyd-Steinberg) dithering.  You can also use it on RGB or even palette images
+(for example, to further color-reduce them to 16 colors).  It does:
  - nice reduction of all PNG image types to 256-color (or smaller) palette
  - automatic optimization of tRNS chunks
  - batch conversion of multiple files (e.g., "pngquant 256 *.png")
  - Unix-style command-line filtering (e.g., "... | pngquant 16 | ...")
- 
-...on at least Unix and Win32.  It should be pretty easy to port to almost
-any other platform with a command-line interface and unstructured (stream-
-oriented) files, including VMS but probably not VM or MVS.
- 
 It does still lack a few features:
- 
  - no ancillary chunk preservation (except gAMA)
  - no preservation of significant-bits info after rescaling (sBIT chunk)
  - no mapfile support
  - no "native" handling of 16-bit-per-sample files or gray+alpha files
-    (i.e., all samples are truncated to 8 bits and all images are promoted
+    (all samples are truncated to 8 bits and all images are promoted
     to RGBA before quantization)

-These issues will be addressed in a post-1.0 release.

 By the way, be sure to check "before" and "after" file sizes, preferably with
 pngcrush (http://pmt.sourceforge.net/pngcrush/); dithered palette images may

 as grayscale and truecolor images.  Some images, such as Henri Sivonen's alpha
 button (http://www.pp.htv.fi/hsivone1/css-test/bitmapstyle.html), can be made
 smaller as full 32-bit RGBA images (4076 bytes in this case) than as either
 FS-dithered palette (4550 bytes) or ordered-dither palette (4482 bytes) images.
