D1227: Print Rasterization Event
This message is emitted from Direct2D print. It indicates that one of the following operations caused a need for rasterization:
- Use of a D2D1_LAYER_OPTIONS1_INITIALIZE_FROM_BACKGROUND layer.
- Use of the primitive blend mode SOURCE COPY, or any blend mode other than SOURCE OVER.
- Use of certain composite modes such as BOUNDED_SOURCE_COPY, DESTINATION_OUT, SOURCE_ATOP, XOR, PLUS, or INVERT.
- Use of DrawGdiMetafile.
- Use of a 4x4 (or, perspective) transformation in a DrawBitmap call.
For optimal performance, these operations should be avoided if possible.
