- /* pngtest.c - a simple test program to test libpng
- *
- * libpng 1.2.8 - December 3, 2004
- * For conditions of distribution and use, see copyright notice in png.h
- * Copyright (c) 1998-2004 Glenn Randers-Pehrson
- * (Version 0.96 Copyright (c) 1996, 1997 Andreas Dilger)
- * (Version 0.88 Copyright (c) 1995, 1996 Guy Eric Schalnat, Group 42, Inc.)
- *
- * This program reads in a PNG image, writes it out again, and then
- * compares the two files. If the files are identical, this shows that
- * the basic chunk handling, filtering, and (de)compression code is working
- * properly. It does not currently test all of the transforms, although
- * it probably should.
- *
- * The program will report "FAIL" in certain legitimate cases:
- * 1) when the compression level or filter selection method is changed.
- * 2) when the maximum IDAT size (PNG_ZBUF_SIZE in pngconf.h) is not 8192.
- * 3) unknown unsafe-to-copy ancillary chunks or unknown critical chunks
- * exist in the input file.
- * 4) others not listed here...
- * In these cases, it is best to check with another tool such as "pngcheck"
- * to see what the differences between the two files are.
- *
- * If a filename is given on the command-line, then this file is used
- * for the input, rather than the default "pngtest.png". This allows
- * testing a wide variety of files easily. You can also test a number
- * of files at once by typing "pngtest -m file1.png file2.png ..."
