Its focus is on performance so if the image data that is presented to the ImagePresenter is in a format that is non-optimal for drawing the data will generally be converted to a format that is optimal, at the expense of a greater usage of memory (see setImageData methods). This process is controlled by the optimised redrawing flag, which if true (the default), may convert the image to a better format for drawing performance.<P><HR><P><!-- ======== INNER CLASS SUMMARY
