The ICM_DRAW_STOP message is sent to a rendering driver to stop its internal clock for the timing of drawing frames.
Parameters
dwParam1
Not used.
dwParam2
Not used.
Return Value
None.
Comments
This message is used only by hardware that does its own asynchronous decompression, timing, and drawing.
The ICM_DRAW_STOP and ICM_DRAW_START messages do not nest. If your driver receives ICM_DRAW_START before rendering is stopped with ICM_DRAW_STOP, it should restart rendering with new parameters.
