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