checking the internal 32-bit CRCs, a.k.a. checksums, and decompressing the image

data); it can optionally dump almost all of the chunk-level information in the image
 |

in human-readable form.  For example, it can be used to print the basic statistics
 | 
						||
about an image (dimensions, bit depth, etc.); to list the color and transparency info
 | 
						||
in its palette (assuming it has one); or to extract the embedded text annotations.

This is a command-line program with batch capabilities (e.g. @code{pngcheck

*.png}.)

     "JBIG2 is designed for lossy or lossless encoding of @code{bilevel} (1-bit

monochrome) images at moderately high resolution, and in particular scanned

paper documents.  In this domain it is very efficient, offering compression

ratios on the order of 100:1.

This is a decoder only implementation, and currently is in the alpha

stage, meaning it doesn't completely work yet.  However, it is

maintaining parity with available encoders, so it is useful for real

work.")

     "JBIG-KIT implements the JBIG1 data compression standard (ITU-T T.82 and
 | 
						||
ISO/IEC 11544:1993), designed for bi-level (one bit per pixel) images such as
 | 
						||
black-and-white scanned documents.  It is widely used in fax products, printer
 | 
						||
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.")
