Description

cmMergeCopy is a TCopyMode value used in the TCanvas CopyMode property.  

The CopyMode property is used by the CopyRect routine when copying an image from another canvas onto the current canvas.  

cmMergeCopy results in the pixels in the source and destination rectangles being logically ANDed. For example, a green pixel in the source will merge with a blue destination pixel to result in a cyan pixel.
