Description
Sets the compositing mode of this
Graphics
object.
Syntax
GpStatus WINGDIPAPI GdipSetCompositingMode(
GpGraphics
*graphics,
CompositingMode
compositingMode
);
PowerBASIC Syntax
DECLARE FUNCTION GdipSetCompositingMode ( _
BYVAL graphics
AS DWORD, _
BYVAL
compositingMode AS LONG _
) AS LONG
Parameters
graphics
[in] Pointer to the
Graphics
object.
compositingMode
[in] Element of the
CompositingMode
enumeration that specifies the compositing mode.
Remarks
Suppose you create a
SolidBrush
object based on a color that has an alpha component of 192, which is
about 75 percent of 255. If your Graphics object
has its compositing mode set to CompositingModeSourceOver,
then areas filled with the solid brush are a blend that is 75 percent
brush color and 25 percent background color. If your Graphics
object has its compositing mode set to CompositingModeSourceCopy,
then the background color is not blended with the brush color. However,
the color rendered by the brush has an intensity that is 75 percent of
what it would be if the alpha component were 255.
You cannot use CompositingModeSourceCopy
along with TextRenderingHintClearTypeGridFit.
