Produces a Image out of a series of renderers, provides viewport pane notification when content changes.

This method is guaranteed not to block.

Usually the image will merge the images for each layer.

Note: The declaration of getContext is declared in IRender so the return type cannot be declared in this interface

This method is guaranteed not to block.

Usually the image will merge the images for each layer. However in some cases, such as for a WMS, the image will have to be recreated. This should be a quick operation.

Note: This command differs from render. render() forces a full rerendering of the data whereas refreshImage does not require that the renderer access the data again.
throws:
