About:
libpng (PNG library) is a collection of routines used to create and manipulate PNG format graphics files. The PNG format was designed as a replacement for GIF and, to a lesser extent, TIFF, with many improvements and extensions.

Release focus: N/A

Changes:
This release primarily fixes or works around a number of obscure platform- or compiler-dependent problems. In addition, the distribution now includes MMX (x86) assembler routines from Intel that boost decoding performance by 20-30% (currently MSVC-only, with a gcc/gas port under development) and three complete demo apps in a new "contrib" subdirectory (rpng/rpng2/wpng, with more expected in future releases).

[»] Libpng and Gnome
by Codesurfer - Jul 4th 2000 00:51:14

After installing libpng 1.0.7 my gnome-help-browser segfaulted and the toolbars would not display any png icons. I recompiled imlib to fix the segfault problem and gdk-pixbuff to fix the display problem.
