Detailed Description

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

Library: ilvproto

IlvZoomXAccessor controls the horizontal 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

IlvZoomXAccessor::IlvZoomXAccessor	(	const char *	name,
		const char *	nodename,
		const char *	centerX
	)

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.
	centerX	Defines the scale center. centerX can contain a constant value, the name of another attribute, or an arithmetic expression that can contain attribute names and/or constants (see IlvUserAccessor::getValue).
