Summary

Provides methods for creating and manipulating raster bitmap images.

Description

The TGPBitmap class inherits from the TGPImage class. The TGPImage class provides methods for loading and saving vector images (metafiles) and raster images (bitmaps). The TGPBitmap class expands on the capabilities of the TGPImage class by providing additional methods for creating and manipulating raster images.
