Hello,
My goal is to use GDI+ for a circular gauge, such as an analog altimeter. In order to do this, I need to use the IMAGE_CREATE_DIBSECTION drawing flag. The problem when using this drawing flag is that the whole rectangular area dedicated to the gauge is drawn black, even if IMAGE_USE_TRANSPARENCY is also used. It means I can not integrate my altimeter in the 2D panel where a circular bezel is drawn...
Does anyone have any clue to solve this problem?
Thanks,
Eric
