Chapter 1. Creating Graphics with Perl
Almost every modern application goes beyond plain text. Graphics appear in the form of logos, icons, charts, animations, or even as a “Save as PDF” option. These graphics can be images (static pictures), animations (moving pictures, possibly interactive), and documents (formatted pages of text and images).
You have several choices of representation for each type of graphic. For example, images are often kept as JPEG or GIF files. But the JPEG format and the GIF format are quite different, and impose different restrictions on the types of images you can store.
