MaskBlt behaves like BitBlt when no mask bitmap is specified. It does a SRCOPY operation when also no Rop is specified. See BitBlt for general information about raster operations.
Rop contains both a foreground and a background raster operation (see MakeROP4). When a (monochrome) mask bitmap is present, its bits select either the foreground (1) or background (0) raster operation.

Copies part of a source DC into a destination DC, using the specified raster operation. |
|
|
Copies a rectangular region to a device context, shrinking or stretching it as needed. |
