See CRAN or files section for the latest release. Plese use install.packages("GDD") to install it.

The main purpose of this package is to replace png/jpeg and similar native devices in R which either rely on X11 or use GhostScript are thus are very slow and not suitable in server applications. GDD also supports advanced features such as anti-aliasing of both lines and text. For full-featured operation it requires gd-2.0.29 or higher with freetype support. Since GDD 0.1-4 gdlib-conf is used to detect GD for more reliable flag detection. See the README file inside the package for details on requirements and font handling.

Note: In most cases GDD can be superseded by the Cairo package which uses cairo graphics library and supports semi-transparent drawing.
