Syntax
Delphi:
property CompositingMode : TGPCompositingMode read GetCompositingMode write SetCompositingModeProp;
C++ Builder:
__property TGPCompositingMode CompositingMode = { read=GetCompositingMode, write=SetCompositingModeProp };
Summary
Sets or gets the compositing mode of the TGPGraphics object.
Description
Use this property to set or get the compositing mode of the
TGPGraphics object.
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.
