Detailed Description

Extension of CanvasImage to display a HxImageRep (C++ image).

There are several "images" involved in this class. First of all there is the C++ image (known by its SA name). Since the C++ image can be both 2D and 3D we also hava a "display image". The display image is determined by the viewing direction and the display plane. The sizes of the display image (\_dispImWidth and \_dispImHeight) determine the sizes (in ICS) of the CanvasHxImage. For display, CanvasHxImage makes use of a BufferedImage (\_bufIm). The sizes of this image are determined by the sizes of the display image and the resolution at with the CanvasHxImage is to be displayed. For example, \_bufImWidth = round(\_dispImWidth * resolution). The draw method of this class actually draws \_bufIm at the CCS coordinates. So, Graphics.drawImage does the actual zooming of the pixel data.
