Chapter 11. The Graphic Arts
The biggest innovation in the original NCSA Mosaic web browser — the one that that changed the Web from just a way to hyperlink physics papers into a multimedia content platform — was the img tag, supporting inline image display. Since then, the capability to manipulate graphics has remained an important part of working on the Web.
This chapter examines several ways to integrate dynamic graphics into your web system. You'll see how to acquire images from the user via file upload. You'll explore the various libraries available for manipulating images from within Ruby, and take a look at some packages for creating charts from those images.
