This method allows a compute-shader–based transform to select the number of thread groups to execute based on the number of output pixels it needs to fill.
Type: const D2D1_RECT_L*
The output rectangle that will be filled by the compute transform.
Type: UINT32*
The number of threads in the x dimension.
Type: UINT32*
The number of threads in the y dimension.
Type: UINT32*
The number of threads in the z dimension.
Type: HRESULT
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
If this call fails, the corresponding ID2D1Effect instance is placed into an error state and fails to draw.
