    where is it?

    I have made an offscreen dc. I used createcompatibledc and bitmap , and selectobject. But how can I get the position in memory of where each pixel color is located?

    Thanx in advance!

    The quick and easy (but slow) way to get colour information is to use GetPixel. The not so easy way is to use GetDIBits.

    Thanx. Thats copying back and forth. Ill do that if I can't find my answer. I remember there is a way to do direct read/write access. If I can just find it in memory I can use pointers to modify the pixels. I am still researching. Maby it is GetObjectA.
