Using the display.getImage(true) will ensure that the image is completely rendered, but also has the added overhead of rerendering the entire display. For a complex display (many scalarmaps and views of data), this is time consuming (but it does work). Perhaps we need a captureImage(Display, String, boolean) to allow an easy interface to the display.getImage(boolean) method. To answer your second question, there is no easy way to determine when a frame is done. DisplayImpl.Syncher does this, but it has to rerender the entire display. Sure would be nice to have an easy way to determine when the "Please wait..." message disappears (i.e. the display is done transforming). Watching for FRAME_DONE events or TRANSFORM_DONE events does not ensure that the Display is "DONE". For any given display, you may get multiples of these events.
