To display other sizes

The display defaults to a size of $512\times 512$ pixels. The size of the display can be changed to match the image. Available sizes are:

    1  2  512  512           OA# imt1|imt512
    2  2  800  800           # imt2|imt800
    3  2 1024 1024           # imt3|imt1024
    4  1 1600 1600           # imt4|imt1600
    5  1 2048 2048           # imt5|imt2048
    6  1 4096 4096           # imt6|imt4096
    7  1 4096 1024           # imt7|imt4x1
    8  1 1024 4096           # imt8|imt1x4
    9  2 1142  880           # imt9|imtfs   full screen (1152x900 minus frame)

To change the size:

  tv> set stdimage=''imt3''   # sets the size of the screen buffer to 1024x1024
  tv> xdisplay ``xdata$rp110590.qp[bl=15]''         # reduces the 15,360 square
                                                  # image to a 1024x1024 array.
                                    # The central 512x512 section is displayed.

The full image is loaded into the buffer and a part of the image displayed depending on the physical size of the windows. The par and center menu option can be used to center on different sections of the image in the buffer or the SAOimage window can be physically resized to display the full $1024\times 1024$.
