Detailed Description

Default WorldCanvas SizeControl handler.

Etymology

DefaultWCSizeControlHandler - Default WorldCanvas Size Control Handler.

Synopsis

This class implements default functionality for the size control handler that the WorldCanvas creates for itself when the WorldCanvas constructor is called.

Presently the default size control handler does nothing, relying on the WCResampleHandler to fit output images to the screen pixel array when images are supposed to be drawn.

Motivation

Wanted to have default functionality for this to make it easier on the user of this class and to avoid having to check all the time in the WorldCanvas to see if a size control handler has been registered.

Example

none available yet.

To Do

• provide example
• consider restricting interface to accepting and modifying a rectangle representing the largest available plotting size.
