c4d.bitmaps.GeClipMap

class c4d.bitmaps.GeClipMap
This class stores and manipulates a bitmap, providing more advanced drawing tools than BaseBitmap.
Just like for bitmaps x = y = 0 is the top left corner.
Be sure to call GeClipMap.Init(), GeClipMap.InitWith() or GeClipMap.InitWithBitmap() before you attempt to use a newly allocated clip map.

Note

Though clip maps support other bit depths than 32, the functionality is severely limited.
It is recommended that the clip map class is only used for 32 bit bitmaps.
Please note that the default bit depth for BaseBitmap is 24. You need to manually set it to 32 if you use Init to initialize the clip map.
