Please note:
• Remember that the horizontal and vertical sizes can be adjusted
independently. For example, if you simply want to “stretch” an image
horizontally, enter the same values for x, y and height, and simply
change the width.
• In Appendix A, refer to the “Image Rectangles” section for addition
details on WSR and WDR commands.
