The Xbase++ Graphics Engine (GRA) Foundation

This chapter describes the Xbase++ GraphicsEngine (GRA engine) which provides the programmer a convenient environment for graphic output. The GRA engine provides functional access to the graphic output system. It includes a total of 32 functions which can be used to easily create simple, up-to-date business graphics such as bar charts and pie diagrams. The GRA engine can also display bitmaps and metafiles and modify the appearance of dialog elements (Xbase-Parts).
