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.
