1 | \section{\class{wxMask}}\label{wxmask} |
| 2 | ||
| 3 | This class encapsulates a monochrome mask bitmap, where the masked area is black and | |
| 4 | the unmasked area is white. | |

| 10 | \wxheading{Remarks} | |
| 11 | ||
| 12 | A mask may be associated with a \helpref{wxBitmap}{wxbitmap}. It is used in \helpref{wxDC::Blit}{wxdcblit} when | |
| 13 | the source device context is a \helpref{wxMemoryDC}{wxmemorydc} with wxBitmap selected into it that | |
| 14 | contains a mask. | |
