Properties

	Name	Description
	Bottom	A numeric value representing the Y coordinate of the bottom side of a bounding box, in canvas coordinates.
	Height	A numeric value representing the height of the bounding box, measured in canvas coordinates.
	Left	A numeric value representing the X coordinate of the left side of a bounding box, in canvas coordinates.
	Origin	A point representing the location of a bounding box, in canvas coordinates.
	Right	A numeric value representing the X coordinate of the right side of a bounding box, in canvas coordinates.
	Top	A numeric value representing the Y coordinate of the top side of a bounding box, in canvas coordinates.
	Width	A numeric value representing the width of the bounding box, in canvas coordinates.

Methods

	Name	Description
	ConvertToScreen	Convert a bounding box to screen coordinates for a given window.
	Destroy	Free memory resources allocated for a VObject object and its derived objects. (Inherited from VObject.)
	PointInside	Test whether a given point is within the bounds of a bounding box.
	Union_	Return a new bounding box that represents the minimum area required to contain both this bounding box and the bounding box specified by oBoundingBox.

Fields

	Name	Description
	oCargo	Cargo slot. (Inherited from VObject.)

Remarks

Typically, the rectangle is the smallest one that encloses both the overall size and position of another object (for example, a drawing or an area of a window that needs repainting).

Tip
A bounding box has no graphical representation—it is just four numbers encapsulated in a class.

Examples

The following returns the smallest rectangle that encloses an EllipseObject object, in canvas coordinates:
