The primary intention of this module is to provide high-level operations for creating, loading, saving and manipulating vector graphics without having to be overly concerned about smile floormats. As the code has seen more use, it has also drifted into a general purpose geometry API.

This is a Perl implementation of the reCAPTCHA API. From the recaptcha.net web site: reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.

Chart::Clicker aims to be a powerful, extensible charting package that creates really pretty output. Clicker leverages the power of Cairo to create snazzy 2D graphics easily and quickly. At it's core Clicker is more of a toolkit for creating charts. It's interface is a bit more complex because making pretty charts requires attention and care. Some fine defaults are established to make getting started easier, but to really unleash the potential of Clicker you must roll up your sleeves and build things by hand.

This Perl module is to plot graphs using GNUPLOT on the fly. In order to use this module, gnuplot need to be installed. If image format other than PS and EPS is required to generate, it is recommended to install the convert program of ImageMagick as well.

Graph.pm is a wrapper module that allows easy generation of graphs within perl. Currently Graph.pm supports three graphing packages, gnuplot, XRT, and Xmgrace. These software packages must be obtained separately from this Perl module. Information on each graphing package and it's availability is provided in the documentation on that module.

Chart::PNGgraph is a perl5 module to create and display PNG output for a graph. The following classes for graphs with axes are defined: Chart::PNGgraph::lines Create a line chart. Chart::PNGgraph::bars Create a bar chart. Chart::PNGgraph::points Create an chart, displaying the data as points. Chart::PNGgraph::linespoints Combination of lines and points. Chart::PNGgraph::area Create a graph, representing the data as areas under a line. Chart::PNGgraph::mixed Create a mixed type graph, any combination of the above. At the moment this is fairly limited. Some of the options that can be used with some of the individual graph types won't work very well. Multiple bar graphs in a mixed graph won't display very nicely. Chart::PNGgraph::pie Create a pie chart.

Color::Rgb - simple rgb.txt parsing class.

This module is an attempt to build a general purpose graphing module that is easily modified and expanded. I borrowed most of the API from Martien Verbruggen's GIFgraph module. I liked most of GIFgraph, but I thought it was to difficult to modify, and it was missing a few things that I needed, most notably legends. So I decided to write a new module from scratch, and I've designed it from the bottom up to be easy to modify. Like GIFgraph, Chart::* uses Lincoln Stein's GD module for all of its graphics primitives calls.

The module implements simple calculations with RGB colors. This can be used to create a full color scheme from a few colors.

Color::Library is an easy-to-use and comprehensive named-color dictionary. Currently provides coverage for www (svg, html, css) colors, x11 colors, and more.
