| 9 | |
| 10 | Replaced and extended code that was removed from png_set_filler() in 1.0.1a. |
| 11 | Fixed a bug in png_do_filler() that made it fail to write filler bytes in |

| 13 | Changed "static pngcharp tIME_string" to "static char tIME_string[30]" |
| 14 | in pngtest.c (Duncan Simpson). |
| 15 | Fixed a bug in pngtest.c that caused pngtest to try to write a tIME chunk |
| 16 | even when no tIME chunk was present in the source file. |
| 17 | Fixed a problem in pngrutil.c: gray_to_rgb didn't always work with 16-bit. |
| 18 | Fixed a problem in png_read_push_finish_row(), which would not skip some |
| 19 | passes that it should skip, for images that are less than 3 pixels high. |
| 20 | Interchanged the order of calls to png_do_swap() and png_do_shift() |
| 21 | in pngwtran.c (John Cromer). |

| 34 | Removed trailing blanks from all files. |
| 35 | Removed misplaced #endif and #ifdef PNG_NO_EXTERN near the end of png.h |
| 36 | Added "if" tests to silence complaints about unused png_ptr in png.h and png.c |
| 37 | Changed "check_if_png" function in example.c to return true (nonzero) if PNG. |
| 38 | Changed libpng.txt to demonstrate png_sig_cmp() instead of png_check_sig() |
