Detailed Description

TMCOffscreen is a platform specific block of pixels (bitmap) that can be sent quickly to the screen. The block is generally padded for alignment, so you must use GetBaseAddress() + rowIndex * GetRowBytes() to find the begining of a row.

The PixelBucket() method returns a TMCPixelBucket that references the memory of the offscreen, and that you can either manipulate directly, or pass to other functions.

TMCOffscreen owns its memory and will delete it. But since TMCOffscreen is not a counted object, you'll need to explicitely delete the offscreen. So it is a good idea to use a smart poimter: TMCSmartPtr <tmcoffscreen> offscreen;
