The ImageFile type exposes the following members.
Called when the RDK is cleaning up old render image files, a plug-in should delete any plug-in specific image files at this time.
Generally called when the "RenderOpenLastRender" command is run, this event is raised after the render window has been created and the saved scene has been loaded.
Render image file saved, happens when a rendering completes. If a plug-in needs to save additional file information it should write it to the same folder as the Rhino render image file. Rhino will take care of deleting old data.
