Description

This class represents a resource of type RT_BITMAP.

A bitmap resource contents is very similar to a BMP file. However some differences exists, so RawData is not appropriate if you need to read and write BMP data. Instead, BitmapData property gives access to a BMP file-like stream.

This class doesn't allow its type to be changed to anything else than RT_BITMAP. Attempts to do so result in a EResourceDescChangeNotAllowedException.
