IAMTimelineTrans::GetSwapInputs

The GetSwapInputs method retrieves a value that indicates whether the transition inputs are swapped.

By default, a transition goes from the composite of all lower-priority layers to the layer where the transition resides. You can reverse this progression, so the transition goes from the layer where it resides back to the composite of lower-priority layers.

Syntax

  HRESULT GetSwapInputs(
    BOOL *pVal
);

Parameters

pVal

Pointer to a variable that receives a Boolean value. If the value is FALSE, the transition goes from the composite of all lower-priority layers to the transition layer. If the value is TRUE, the transition goes in the opposite direction. The default value is FALSE.

Return Value

Returns S_OK if successful, or E_POINTER otherwise.
