GpiDrawBits copies bit map image data from storage into a bit map that has been selected into a device context associated with a presentation space. It can also copy bit-map image data to a device. An application can use this function to draw a bit map without first selecting the bit map into a presentation space.
This function is valid in all draw modes. Set the draw mode to DM_RETAIN or DM_DRAWANDRETAIN to create retained segments; otherwise, the default mode, DM_DRAW, is selected.
