PNG Source Code
For those of you who like to go the do-it-yourself route, here are the tools
to make your PNG code go (some of which may also be provided with ready-to-go
executables). Some of the code, particularly by members of the PNG Development
Group, is still kept up to date at the primary Simple Systems ftp site,
but for most things check the appropriate PNG Applications pages for current
links. (This page was previously called Code from the PNG Development
Group and later PNG Source Code and Libraries. Now it is simply
a list of applications, libraries and toolkits that include source code, with
more complete descriptions on the relevant PNG applications pages. The two
main PNG-related libraries, libpng and zlib, are linked directly
and are still maintained by members of the PNG Group, though.)
Latest releases:
libpng 1.6.19
[license]
zlib 1.2.7
[Y2K]
[license]
The following programming libraries, toolkits, DLLs and Java classes all
include source code and are listed on the toolkits
page. Operating-system support is listed in (parenthesized italics),
and toolkits that do not derive their PNG support from another listed library
(typically libpng)--although they may or may not require zlib--are so noted.
(See also Quat in the 3D section for another independent, zlib-based,
C implementation of a PNG codec.)
