Title: A description on how to use and modify libpng (version 1.2.X)
Author: Glenn Randers-Pehrson
Abstract: This file describes how to use and modify the PNG reference library
(known as libpng) for your own use. There are five sections to this
file: introduction, structures, reading, writing, and modification and
configuration notes for various special platforms. In addition to this
file, example.c is a good starting point for using the library, as
it is heavily commented and should include everything most people
will need. We assume that libpng is already installed; see the
INSTALL file for instructions on how to install libpng.
.
Libpng was written as a companion to the PNG specification, as a way
of reducing the amount of time and effort it takes to support the PNG
file format in application programs. The PNG specification is available
as RFC 2083 <http://www.ietf.org/rfc/rfc2083.txt> and as a
W3C Recommendation <http://www.w3.org/TR/REC-png-multi.html>. Some
additional chunks are described in the special-purpose public chunks
documents at <ftp://ftp.uu.net/graphics/png/documents/>. Other information
about PNG, and the latest version of libpng, can be found at the PNG home
page, <http://www.libpng.org/pub/png/>.
