13503VIRT.EXE DISPLAY UTILITY
13503VIRT.EXE demonstrates the virtual panning capabilities of the S1D13503. Two images larger than the display
resolution are loaded in display memory. 13503VIRT.EXE will then display, in a split screen, a portion of each complete
image while providing panning capabilities using the arrow keys for navigation.
Program Requirements
Installation
Copy the file 13503virt.exe to a directory that is in the DOS path on your hard drive.
Usage
13503VIRT is invoked from the DOS command line as follows:
13503virt g=n [/a] [/k] [/?]
Where:
g
is the number of gray shades/colors: 2, 4, 16 or 256.
/a
automatically pan and scroll the image - useful for demonstrations.
/k
exit the program and keep the image on the display - useful in batch file execution
for demonstrations.
/?
produces a usage message.
The program draws a test pattern of two images on the display. The user can navigate throughout either image using the
numeric keypad. Use the arrow keys to pan and scroll the screen, Home to go to the top left, PG UP to go to the top right,
End to go to the bottom left, Pg Dn to go to the bottom right, and 5 to go to the center of the image. Pressing Ctrl while
using an arrow key steps the scroll or pan in smaller increments. Press the Num Lock key to allow navigation in the second
image.
Holding down the Shift key while pressing either the up or down arrow will move the split up or down.
Pressing the ESC key terminates the program.
