All pixel formats supported by ImageGear Professional, except:
Call this function periodically to flush the DIB if the application accesses individual pixels or rasters of an image, or accesses pixel data directly by the image or raster pointer, and the DIB uses a memory mapped file for storing pixels. Usually, it is sufficient to flush the DIB after accessing of 100 - 200 Mb of pixel data.
If memory mapping is not used for the DIB, the function does nothing.
