Using Regions to Perform Hit Testing

The example in Brushes uses regions to simulate a "zoomed" view of an 8- by 8-pixel monochrome bitmap. By clicking on the pixels in this bitmap, the user creates a custom brush suitable for drawing operations. The example shows how to use the PtInRegion function to perform hit testing and the InvertRgn function to invert the colors in a region.
