+ Introduction +

+ The egd module is an interface for 2d-image rendering and is used by + Percept to generate dynamic graphs to its web pages. All code is pure + erlang, no drivers needed. +

+

+ The library is intended for small to medium image sizes with low + complexity for optimal performance. The library handles horizontal + lines better then vertical lines. +

+

+ The foremost purpose for this module is to enable users to + generate images from erlang code and/or datasets and to + send these images to either files or web servers. +

+
