* CachedBitmap | |
* | |
* Abstract: | |
* | |
* An object to store a bitmap prepared for rendering on a particular | |
* Graphics object. The memory storage for the CachedBitmap is opaque | |
* to the other Engine code, so the only operations supported are | |
* initializing the data (with a bitmap) and using the graphics to | |
* draw it on the screen with an integer offset. | |
* | |
* Look for the class definition in GdiplusHeaders.h | |
