Libpng 1.0.2a - December 29, 1998
Libpng 1.0.2b - January 6, 1999

within a few weeks by a public version or by another test version.
Changes since the last public release:
libpng-1.0.2a:
version 1.0.2a [December 30, 1998]
Replaced and extended code that was removed from png_set_filler() in 1.0.1a.
Fixed a bug in png_do_filler() that made it fail to write filler bytes in
the left-most pixel of each row (Kevin Bracey).
Changed "static pngcharp tIME_string" to "static char tIME_string[30]"
in pngtest.c (Duncan Simpson).
Fixed a bug in pngtest.c that caused pngtest to try to write a tIME chunk
even when no tIME chunk was present in the source file.
Fixed a problem in pngrutil.c: gray_to_rgb didn't always work with 16-bit.
Fixed a problem in png_read_push_finish_row(), which would not skip some
passes that it should skip, for images that are less than 3 pixels high.
@ -31,6 +32,12 @@ libpng-1.0.2a:
Removed lines after Dynamic Dependencies" in makefile.aco .
Revised makefile.dec to make a shared library (Jeremie Petit).
Removed trailing blanks from all files.
version 1.0.2b [January 6, 1999]
Removed misplaced #endif and #ifdef PNG_NO_EXTERN near the end of png.h
Added "if" tests to silence complaints about unused png_ptr in png.h and png.c
Changed "check_if_png" function in example.c to return true (nonzero) if PNG.
Changed libpng.txt to demonstrate png_sig_cmp() instead of png_check_sig()
which is obsolete.
