| 10 | * This program reads in a PNG image, writes it out again, and then |
| 11 | * compares the two files. If the files are identical, this shows that |
| 12 | * the basic chunk handling, filtering, and (de)compression code is working |
| 13 | * properly. It does not currently test all of the transforms, although |
| 14 | * it probably should. |
| 15 | * |
Glenn Randers-Pehrson | 345bc27 | 1998-06-14 14:43:31 -0500 | [diff] [blame] | 16 | * The program will report "FAIL" in certain legitimate cases: |
Glenn Randers-Pehrson | b6ce43d | 1998-01-01 07:13:13 -0600 | [diff] [blame] | 17 | * 1) when the compression level or filter selection method is changed. |
Glenn Randers-Pehrson | 61c32d9 | 2000-02-04 23:40:16 -0600 | [diff] [blame] | 18 | * 2) when the maximum IDAT size (PNG_ZBUF_SIZE in pngconf.h) is not 8192. |
Glenn Randers-Pehrson | 5e5c1e1 | 2000-11-10 12:26:19 -0600 | [diff] [blame] | 19 | * 3) unknown unsafe-to-copy ancillary chunks or unknown critical chunks |
| 20 | * exist in the input file. |
Glenn Randers-Pehrson | b6ce43d | 1998-01-01 07:13:13 -0600 | [diff] [blame] | 21 | * 4) others not listed here... |
| 22 | * In these cases, it is best to check with another tool such as "pngcheck" |
Glenn Randers-Pehrson | 61c32d9 | 2000-02-04 23:40:16 -0600 | [diff] [blame] | 23 | * to see what the differences between the two files are. |
Glenn Randers-Pehrson | b6ce43d | 1998-01-01 07:13:13 -0600 | [diff] [blame] | 24 | * |
| 25 | * If a filename is given on the command-line, then this file is used |
| 26 | * for the input, rather than the default "pngtest.png". This allows |
Glenn Randers-Pehrson | f7d1a17 | 1998-06-06 15:31:35 -0500 | [diff] [blame] | 27 | * testing a wide variety of files easily. You can also test a number |
| 28 | * of files at once by typing "pngtest -m file1.png file2.png ..." |
