Image::PNG::Libpng is a "module" for the Perl computer programming language, a library of computer code to install on a computer. This document contains four sections: 1. About - what the module does 2. Documentation - how to learn more about the module 3. Installation - how to install this module on a computer 4. Help - what to do if you get stuck ----------------------------------------------------------------------------- 1. ABOUT Image::PNG::Libpng - Perl interface to libpng This is a low-level library for accessing the contents of PNG graphics. PNG means Portable Network Graphics and it is a common standard for graphics. Image::PNG::Libpng enables Perl to use the "libpng" library for reading and writing files in the PNG format. Image::PNG::Libpng does not contain "libpng". "libpng" must be installed on the computer prior to installing Image::PNG::Libpng. Image::PNG::Libpng consists of Perl subroutines which mirror the C functions in libpng, plus helper subroutines to make it easier to read and write PNG data in Perl. For those familiar with libpng, to know what the differences between this module and libpng are, please go to the section "Differences from libpng". For those not familiar with libpng, the module basically mirrors the C interface of libpng. An extension of this module, "Image::PNG", is intended to give a more intuitive interface to the library. ----------------------------------------------------------------------------- 2. DOCUMENTATION You can read the documentation for the module online at the following websites: * http://search.cpan.org/perldoc?Image::PNG::Libpng * http://metacpan.org/release/Image-PNG-Libpng (These links go to the latest version of the module.) After installing the module, you can read the documentation on your computer using perldoc Image::PNG::Libpng ----------------------------------------------------------------------------- 3. INSTALLATION This module requires Perl version 5.8.1 or later. To install the module from CPAN, use cpan Image::PNG::Libpng If you have the App::cpanminus installer, you may prefer cpanm Image::PNG::Libpng To install the module from the source file, Image-PNG-Libpng-0.35.tar.gz, follow this sequence of commands: tar xfz Image-PNG-Libpng-0.35.tar.gz cd Image-PNG-Libpng-0.35 perl Makefile.PL make make install If you want to test the module before installing it, use "make test" after "make" and before "make install". ----------------------------------------------------------------------------- 4.
