sizes by converting images to a more efficient 8-bit PNG format with alpha
channel (often 60-80% smaller than 24/32-bit PNG files). Compressed images
are fully standards-compliant and are supported by all web browsers and
operating systems.
Features:
@enumerate
@item High-quality palette generation using a combination of vector
quantization algorithms.
@item Unique adaptive dithering algorithm that adds less noise to images

firmware and drivers, document management systems, and imaging software.
This package provides a static C library of (de)compression functions and some
simple command-line converters similar to those provided by netpbm.
Two JBIG1 variants are available. One (@file{jbig.c}) implements nearly all
options of the standard but has to keep the full uncompressed image in memory.
The other (@file{jbig85.c}) implements just the ITU-T T.85 profile, with
memory management optimized for embedded and fax applications. It buffers
only a few lines of the uncompressed image in memory and is able to stream
images of initially unknown height.")

(description "SNG (Scriptable Network Graphics) is a minilanguage designed
specifically to represent the entire contents of a PNG (Portable Network
Graphics) file in an editable form. Thus, SNGs representing elaborate
graphics images and ancillary chunk data can be readily generated or modified
using only text tools.
SNG is implemented by a compiler/decompiler called sng that
losslessly translates between SNG and PNG.")
