§ doTransition()

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
schedulerThe scheduler that triggered the transition.
oldRateThe old rate. Valid values are double values in the interval 0-100.
newRateThe new rate. Valid values are double values in the interval 0-100.

Implements IlvTransitionHandler.

§ startTransition()

virtual void IlvBitmapTransitionHandler::startTransition ( IlvTransitionScheduler scheduler)
virtual

Called by the scheduler when starting the transition.

The default implementation does nothing.

Parameters
schedulerThe scheduler that triggered the transition.

Reimplemented from IlvTransitionHandler.
