Member Function Documentation

void tuttle::plugin::timeShift::TimeShiftPlugin::getFramesNeeded	(	const OFX::FramesNeededArguments &	args,
		OFX::FramesNeededSetter &	frames
	)		`[virtual]`

the get frames needed action

If the effect wants change the frames needed on an input clip from the default values (which is the same as the frame to be renderred) it should do so by calling the OFX::FramesNeededSetter::setFramesNeeded function on the frames argument.

Reimplemented from OFX::ImageEffect.

Here is the call graph for this function:

bool tuttle::plugin::timeShift::TimeShiftPlugin::getTimeDomain ( OfxRangeD & range ) [virtual]

what is the time domain of this effect, valid only in the general context

get the time domain

return true if range was set, otherwise the default (the union of the time domain of all input clips) is used

Reimplemented from OFX::ImageEffect.

Here is the call graph for this function:

bool tuttle::plugin::timeShift::TimeShiftPlugin::isIdentity	(	const OFX::RenderArguments &	args,
		OFX::Clip *&	identityClip,
		double &	identityTime
	)		`[virtual]`

client is identity function, returns the clip and time for the identity function

If the effect would do no processing for the given param set and render arguments, then this function should return true and set the identityClip pointer to point to the clip that is the identity and identityTime to be the time at which to access the clip for the identity operation.

Reimplemented from OFX::ImageEffect.
