ID2D1DrawInfo::SetPixelShader method (d2d1effectauthor.h)

Set the shader instructions for this transform.

Syntax

HRESULT SetPixelShader(
  [in] REFGUID            shaderId,
       D2D1_PIXEL_OPTIONS pixelOptions
);

Parameters

[in] shaderId

Type: REFGUID

The resource id for the shader.

pixelOptions

Type: D2D1_PIXEL_OPTIONS

Additional information provided to the renderer to indicate the operations the pixel shader does.

Return value

Type: HRESULT

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Remarks

If this call fails, the corresponding ID2D1Effect instance is placed into an error state and will fail to Draw, it will place the context into an error state which can be retrieved through the ID2D1DeviceContext::EndDraw call.

Specifying pixelOptions other than D2D1_PIXEL_OPTIONS_NONE can enable the renderer to perform certain optimizations such as combining various parts of the effect graph together. If this information does not accurately describe the shader, indeterminate rendering artifacts can result.
