startFxTime:ofImageParm:

Returns the start time of the clip assigned to the given image parameter.

Declaration

- (void)startFxTime:(FxTime*)startTime ofImageParm:(UInt32)parmId

Parameters

startTime

Receives the start time of the image parameter.

parmId

The ID of the image parameter.

Overview

This method is only meaningful if the image parameter has been assigned a value. To determine whether or not it has, you should first invoke durationFxTime:ofImageParm:. If the return value is kFxDuration_Undefined, then the image parameter has not yet been connected.
