Use the composite effect to combine 2 or more images. This effect has 13 different composite modes. T
The composite effect accepts 2 or more inputs. When you specify 2 images, destination is the first input (index 0) and the source is the second input (index 1). If you specify more than 2 inputs the images are composited starting with the first input and the second and so on.
This effect implements all of the modes using the blending unit of the graphics processing unit (GPU).
The CLSID for this effect is CLSID_D2D1Composite.
The image here shows 2 rounded rectangles of the same size that overlap. The blue rectangle is the source and the red rectangle is the destination. The images were composited with the Source Over mode.
Here's another example using the default mode.

The table here shows the modes of this effect. The equations listed in the table use these elements:
Enumeration | Equation | Output Bitmap Size |
---|---|---|
D2D1_COMPOSITE_MODE_SOURCE_OVER | O = S + (1 SA) * D | Union of source and destination bitmaps |
D2D1_COMPOSITE_MODE_DESTINATION_OVER | O = (1 DA) * S + D | Union of source and destination bitmaps |
D2D1_COMPOSITE_MODE_SOURCE_IN | O = DA * S | Intersection of source and destination bitmaps |
D2D1_COMPOSITE_MODE_DESTINATION_IN | O = SA * D | Intersection of source and destination bitmaps |
D2D1_COMPOSITE_MODE_SOURCE_OUT | O = (1 - DA) * S | Region of the source bitmap |
D2D1_COMPOSITE_MODE_DESTINATION_OUT | O = (1 - SA) * D | Region of the destination bitmap |
D2D1_COMPOSITE_MODE_SOURCE_ATOP | O = DA * S + (1 - SA) * D | Region of the destination bitmap |
D2D1_COMPOSITE_MODE_DESTINATION_ATOP | O = (1 - DA) * S + SA * D | Region of the source bitmap |
D2D1_COMPOSITE_MODE_XOR | O = (1 - DA) * S + (1 - SA) * D | Union of source and destination bitmaps |
D2D1_COMPOSITE_MODE_PLUS | O = S + D | Union of source and destination bitmaps |
D2D1_COMPOSITE_MODE_SOURCE_COPY | O = S | Region of the source bitmap |
D2D1_COMPOSITE_MODE_BOUNDED_SOURCE_COPY | O = S (only where source exists) | Union of source and destination bitmaps. Destination is not overwritten where the source doesn't exist. |
D2D1_COMPOSITE_MODE_MASK_INVERT | O = (1 D) * S + (1 SA) * D | Union of source and destination bitmaps.The alpha values are unchanged. |
The figure here shows an example of each of the modes with images that have an opacity of 1.0 or 0.5.
