ID2D1EffectImpl::SetGraph method (d2d1effectauthor.h)
The renderer calls this method to provide the effect implementation with a way to specify its transform graph and transform graph changes.
The renderer calls this method when:
- When the effect is first initialized.
- If the number of inputs to the effect changes.
Syntax
HRESULT SetGraph(
ID2D1TransformGraph *transformGraph
);
Parameters
transformGraph
Type: ID2D1TransformGraph*
The graph to which the effect describes its transform topology through the SetDescription call.
Return value
Type: HRESULT
An error that prevents the effect from being initialized if called as part of the CreateEffect call. If the effect fails a subsequent SetGraph call:
- The error will be returned from the property method that caused the number of inputs to the effect to change.
- The effect object will be placed into an error state, if subsequently used to render, the context will be placed into a temporary error state, that particular effect will fail to render and the failure will be returned on the next EndDraw or Flush call.
