I am using the PtInRegion function in a program and can't seem to get it to work with a complex region I created using the function CombineRgn. The complex region is made up of multiple retangles, that may not touch each other. My question is whether someone knows if the PtInRegion will work with a complex region such as multiple rectangles either not touching each other or touching each other. I have had success getting the PtInRegion function to work with one rectangle, however, not yet with multiple rectangles.
