XMagick

If you require a reliable library for integrating ImageMagick with any X application, XMagick is what you need. This C-based library bridges the gap by offering functions that convert the native X image format to the native ImageMagick format. ImageMagick is a comprehensive collection of libraries and tools that facilitate reading, writing, and manipulation of an image in the most popular formats such as JPEG, PNG, GIF, PDF, and Photo CD.

With ImageMagick's dynamic GIF creation, it's a perfect choice for web applications that necessitate the dynamic display of images. XMagick's latest release features John Cwikla's XCC technology that effectively deals with PseudoColor by replacing the color allocation code.
