GIF

GIF (Graphics Interchange Format) is a lossless image format that is almost universally supported. GIF images are larger in file size than SVG, Flash, or PNG, and thus take longer to send over the Internet. GIF images print only at a low resolution of 72 DPI.

In order to provide interactivity such as drill down and pop up text with GIF images, an image map must be generated. Thus, user interactivity is very limited. The availability of PopUp text will depend on how the browser displays alt text in an image map. Some browsers show it, but wait a few seconds before doing so. Others are not capable of showing PopUp text with GIF images at all.

PopChart uses the RLE algorithm for creating GIF images, avoiding any licensing issues regarding the LZW algoritm.

In PopChart Server Pro and PopChart Server Enterprise, GIF images are anti-aliased.
