Detailed Description

Class to draw fonts onto an image.

Note: This class requires a font path to be set for the factory: "ossimFontFactoryRegistry". You should set at a minimum the keyword "font.dir1" in your ossim_prefernces file. Example from a RedHat 9.0 system: font.dir1: /usr/share/fonts/default/Type1
