Remarks

A virtual image for all practical purposes is a blank canvas that the application can use in conjunction with the PaintImage event to control rendering of an image. The scrollbars, zoom factor and other attributes of the view are maintained by ImagXpress. This could be used to break a large image into smaller images or tiles for reducing the memory footprint of the application. This is an advanced function and not recommended for use unless there is a extremely valid reason to use it.
