Interface IScalable<T extends IGeometry>

Type Parameters:

T - the implementing type

All Known Implementing Classes:

public interface IScalable<T extends IGeometry>

The IScalable interface collects all scaling short-cut methods.

The scale(double), scale(double, double), scale(double, Point), scale(double, double, double), scale(double, double, Point) and scale(double, double, double, double) methods are directly applied to the calling object. They scale it by the given factor(s) around the given Point or an appropriate default.

On the other hand, the getScaled(double), getScaled(double, double), getScaled(double, Point), getScaled(double, double, double), getScaled(double, double, Point) and getScaled(double, double, double, double) methods are applied to a copy of the calling object.

If you do not specify the relative Point for the scaling, the implementation will appropriately choose one. In most cases, this will be the center of the scaled object.
