cmMergeCopy

Combines the image on the canvas and the source bitmap by using the Boolean AND operator.

cmMergePaint

Combines the inverted source bitmap with the image on the canvas by using the Boolean OR operator.

cmNotSrcCopy

Copies the inverted source bitmap to the canvas.

cmNotSrcErase

Combines the image on the canvas and the source bitmap by using the Boolean OR operator, and inverts the result.

cmPatCopy

Copies the source pattern to the canvas.

cmPatInvert

Combines the source pattern with the image on the canvas using the Boolean XOR operator

cmPatPaint
