ID2D1DrawInfo::SetVertexProcessing method

Applies to: desktop apps only

Sets a vertex buffer, a corresponding vertex shader, and options to control how the vertices are to be handled by the Direct2D context.

Syntax


HRESULT SetVertexProcessing(
  [in, optional]  ID2D1VertexBuffer *vertexBuffer,
  D2D1_VERTEX_OPTIONS vertexOptions,
  [in, optional]  const D2D1_BLEND_DESCRIPTION *blendDescription,
  [in, optional]  const D2D1_VERTEX_RANGE *vertexRange
);

Parameters

vertexBuffer [in, optional]

Type: ID2D1VertexBuffer*

The vertex buffer. If this is cleared, the default vertex shader and mapping to the transform rectangles are used.

vertexOptions

Type: D2D1_VERTEX_OPTIONS

Options that influence how the renderer will interact with the vertex shader.

blendDescription [in, optional]

Type: const D2D1_BLEND_DESCRIPTION*

How the vertices will be blended with the output texture.

vertexRange [in, optional]

Type: const D2D1_VERTEX_RANGE*

If specified, the set of vertices to use from the buffer.

Return value

Type: HRESULT

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

HRESULTDescription
S_OKNo error occurred.
E_INVALIDARGOne or more arguments are not valid.

 

Remarks

The vertex shaders associated with the vertex buffer through the vertex shader GUID must have been loaded through the ID2D1EffectContext::LoadVertexShader method before this call is made.

If this call fails, the corresponding ID2D1Effect instance is placed into an error state and fails to draw.
