Detailed Description

Transition Handler class.

Library: views

This class handles transitions between two IlvRGBBitmapData objects. The intermediate bitmaps are computed using the IlvBitmapTransition class.

Constructor & Destructor Documentation

IlvBitmapTransitionHandler::IlvBitmapTransitionHandler	(	IlvBitmapTransition &	transition,
		IlvRGBBitmapData &	image1,
		IlvRGBBitmapData &	image2,
		IlvPort &	dst
	)

Constructor.

Initializes a new instance of the IlvBitmapTransitionHandler class.

Parameters

transition	The object that will compute the intermediate bitmaps.
image1	The source image.
image2	The destination image.
dst	The port where will be copied the intermediate images.

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.

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.
