Overview: Refer to Drawing Simple Objects.
Remarks
(Persistent property, available at design time) Determines how each pixel of a drawing object is combined with the existing pixel on the target surface (the screen or bitmap, as specified by the DrawPersistence property).
For normal drawing, use DRAWMODE_COPY_PEN. The DrawPenColor property specifies the pen color. For rubberband-style interactive display, use DRAWMODE_INVERT (as shown in the code example).
Value Description of the Resulting Pixel
DRAWMODE_BLACKNESS Pixel is always black.
DRAWMODE_COPY_PEN Pixel is the pen color.
DRAWMODE_MASK_NOT_PEN Pixel is a combination of the colors common to both the target and the inverse of the pen.
DRAWMODE_MASK_PEN Pixel is a combination of the colors common to both the pen and the target.
DRAWMODE_MASK_PEN_NOT Pixel is a combination of the colors common to both the pen and the inverse of the target.
DRAWMODE_MERGE_NOT_PEN Pixel is a combination of the target color and the inverse of the pen color.
DRAWMODE_MERGE_PEN Pixel is a combination of the pen color and the target color.
DRAWMODE_MERGE_PEN_NOT Pixel is a combination of the pen color and the inverse of the target color.
DRAWMODE_NOP Pixel remains unchanged.
DRAWMODE_INVERT Pixel is the inverse of the target color.
DRAWMODE_NOT_COPY_PEN Pixel is the inverse of the pen color.
DRAWMODE_NOT_MASK_PEN Pixel is the inverse of the DRAWMODE_MASK_PEN color.
DRAWMODE_NOT_MERGE_PEN Pixel is the inverse of the DRAWMODE_MERGE_PEN color.
DRAWMODE_NOT_XOR_PEN Pixel is the inverse of the DRAWMODE_XOR_PEN color.
DRAWMODE_WHITENESS Pixel is always white.
DRAWMODE_XOR_PEN Pixel is a combination of the colors in the pen and in the target, but not in both.
