ID2D1EffectImpl::SetGraph method

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.
