Color of Pixel
- Thread starter aztined
- Start date
GetPixel isn't enough in this situation, as
a) Images don't have a Device Context
b) Even if you put the Image into a Picturebox instead, GetPixel gets affected by VB's clipping (exactly as does VB's Point command, which is just a wrapper for GetPixel) - pixels that are hidden from display return CLR_INVALID
One solution to this is to pop the picture into a screen-compatible memory DC with no clip region, and call GetPixel against that. I produced a worked example of this in thread222-263560
