ID2D1RenderInfo::SetInstructionCountHint method (d2d1effectauthor.h)
Provides an estimated hint of shader execution cost to D2D.
Syntax
void SetInstructionCountHint(
UINT32 instructionCount
);
Parameters
instructionCount
Type: UINT32
An approximate instruction count of the associated shader.
Return value
None
Remarks
The instruction count may be set according to the number of instructions in the shader. This information is used as a hint when rendering extremely large images. Calling this API is optional, but it may improve performance if you provide an accurate number.
Note Instructions that occur in a loop should be counted according to the number of loop iterations.
