Mergecopy combines the pattern and the source bitmap using the boolean and operator Mergecopy使用and运算符组合模板与源位图的颜色。
Srcand combines pixels of the destination and source bitmaps using the boolean and operator Srcand使用and运算符组合源位图和目标位图的像素。
Srcinvert combines pixels of the destination and source bitmaps using the boolean xor operator Srcinvert使用xor运算符组合源位图和目标位图的像素。
Mergepaint combines the inverted source bitmap with the destination bitmap using the boolean or operator Mergepaint使用or运算符组合源位图的反色与目标矩形的颜色。
Srcerase inverts the destination bitmap and combines the result with the source bitmap using the boolean and operator Srcerase反转目标矩形的颜色,再使用and运算符将该结果与源位图组合。
If a pattern is to be merged with the result , it is not merged until the stretched source bitmap is copied to the destination 如果模板要与结果组合,则在扩展后的位图拷贝到目标矩形后才组合。
