ID2D1RenderInfo::SetInstructionCountHint method

Provides an estimated hint of shader execution cost to D2D.

Syntax

C++


void SetInstructionCountHint(
   UINT32 instructionCount
);

Parameters

instructionCount

Type: UINT32

An approximate instruction count of the associated shader.

Return value

This method does not return a value.

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.
