* 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 program will report "FAIL" in certain legitimate cases:
* 1) when the compression level or filter selection method is changed.
- * 2) when the chunk size is not 8K.
- * 3) unknown ancillary chunks exist in the input file.
+ * 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 images are.
+ * 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
* of files at once by typing "pngtest -m file1.png file2.png ..."
