/* pngtest.c - a simple test program to test libpng
|
||
|
*
|
||
|
* libpng 1.2.5 - October 3, 2002
|
||
|
* For conditions of distribution and use, see copyright notice in png.h
|
||
|
* Copyright (c) 1998-2002 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 ..."
