Member Function Documentation

virtual void IlvBitmapTransitionHandler::doTransition	(	IlvTransitionScheduler &	scheduler,
		IlDouble	oldRate,
		IlDouble	newRate
	)			[virtual]

Called by the scheduler to do the transition.

Override this method to implement your own transition.

Parameters:

	scheduler	The scheduler that triggered the transition.
	oldRate	The old rate. Valid values are double values in the interval 0-100.
	newRate	The new rate. Valid values are double values in the interval 0-100.

Implements IlvTransitionHandler.

virtual void IlvBitmapTransitionHandler::startTransition

(

IlvTransitionScheduler &

scheduler

)

[virtual]

Called by the scheduler when starting the transition.

The default implementation does nothing.

Parameters:

scheduler

The scheduler that triggered the transition.

Reimplemented from IlvTransitionHandler.
