Detailed Description

Behavior to set the Y scaling factor of a graphic object.

Library: ilvproto

IlvZoomYAccessor controls the vertical scaling factor of a graphic object. Each time the attribute is changed, the object is scaled to the attribute value and the new scale setting is stored.

Constructor & Destructor Documentation

IlvZoomYAccessor()

IlvZoomYAccessor::IlvZoomYAccessor	(	const char *	name,
		const char *	nodename,
		const char *	centerY
	)

Creates a new zoom accessor.

This accessor includes an IlvValueAccessor of type float that holds the current scaling factor of the node. It is therefore implicitly typed to IlvFloatValueType.

Parameters

name	Name of the attribute.
nodename	Specifies the name of the node that contains the graphic object to be scaled.
centerY	Defines the scale center. centerY can contain a constant value, the name of another attribute, or an arithmetic expression that can contain attribute names and/or constants.
