573The possible values and their meaning in terms of source and
574destination pixel values are as follows:
575
576 ================ ==========================
577 wx.AND src AND dst
578 wx.AND_INVERT (NOT src) AND dst
579 wx.AND_REVERSE src AND (NOT dst)
580 wx.CLEAR 0
581 wx.COPY src
582 wx.EQUIV (NOT src) XOR dst
583 wx.INVERT NOT dst
584 wx.NAND (NOT src) OR (NOT dst)
585 wx.NOR (NOT src) AND (NOT dst)
586 wx.NO_OP dst
587 wx.OR src OR dst
588 wx.OR_INVERT (NOT src) OR dst
589 wx.OR_REVERSE src OR (NOT dst)
590 wx.SET 1
591 wx.SRC_INVERT NOT src
592 wx.XOR src XOR dst
593 ================ ==========================
594
595The default is wx.COPY, which simply draws with the current
596colour. The others combine the current colour and the background using
597a logical operation. wx.INVERT is commonly used for drawing rubber
598bands or moving outlines, since drawing twice reverts to the original
599colour.
