Bbox2Bvr Class

public class Bbox2Bvr extends Behavior {
    //Methods 
    public Point2Bvr getMax();
    public Point2Bvr getMin();

    public static Bbox2Bvr newUninitBvr();
}

Creates an object that represents a two-dimensional bounding box behavior. The behavior specifies the lower-left and upper-right corners of a box that encloses the non-transparent portions of an image behavior. Although a bounding box may not always be the smallest bounding box achievable for the image, it is useful for determining the extent or size of the visible portions of the image.

Applications never create bounding box behaviors explicitly. Instead, you create these behaviors by calling the boundingBox method in the ImageBvr class.

For more information about behaviors, see the Behavior class.

Methods

getMax

public Point2Bvr getMax();

Creates a two-dimensional point behavior that specifies the upper-right corner of the bounding box.

Return Value:

Returns the Point2Bvr object.

getMin

public getMin();

Creates a two-dimensional point behavior that specifies the lower-left corner of the bounding box.

Return Value:

Returns the Point2Bvr object.

newUninitBvr

public static Bbox2Bvr newUninitBvr();

This method allows you to refer to a two-dimensional bounding box behavior before that behavior has been defined. With this method you can create the behavior and use it in the definition of other behaviors, but not actually define its contents until some later point. (This is accomplished with the init method, which is available on all behaviors.) The system generates a run-time error if you initialize a non-uninitialized behavior, initialize an uninitialized behavior that has already been initialized, or run an initialized behavior that has not yet been initialized.

Return Value:

Returns the Bbox2Bvr object.
