    How to change the Display mode of a Bitmap ?

    hi,
    Suppose I have a CFbsBitmap of higher display mode (EGray256). Now if I want to lower the display mode of the bitmap to EGray16 then what what I need to do? I want to do it without taking any difficulty. If I have don't have to change the bitmap pixel value manually(on that purpose), then it is better.

    Thank you

    You have to create a new bitmap for this purpose and copy the old one to it. But you do not have to do that manually, BitBlt and similar methods can help (getting a graphics context for a bitmap is discussed in topics related to double buffering and "off-screen" bitmaps, even the SDK Help contains a short example).
