USING THE ZOOM UTILITY
The ZOOM utility consists of two RAM resident programs that allow
graphics program running on the Qtec VGA1024 board to perform
hardware zooming, panning and scrolling at the touch of a key.
The programs HOTKEY and HOTZOOM are included on your Utility
Diskette.
The ZOOM utility works by using the BIOS keyboard interrupt to
check for the ZOOM utility programs. Programs such as AutoCAD
permit the use of this keyboard interrupt. Some graphics programs
bypass the keyboard interrupt and may not allow ZOOM to function.
ZOOM is useful when working with interactive programs which allow
editing of the graphics display screen.
The following graphics modes are supported:
RESOLUTION
MODE
DISPLAY
640x200
E
16 colors
640x350 F Monochrome
640x350 10 16 colors
640x480 11 2 colors
640x480 12 16 colors
320x200 13 256 colors
800x600 29 16 colors
Once the programs are installed, you may bring up the ZOOM at any
time within a graphics application by pressing the pre-defined
hotkey. You may specify any key on the keyboard as the hot key.
Before you enter your graphics application, you must load the ZOOM
utility programs into memory. Note that you should only do this
once after booting your PC.
1. Insert the Qtec VGA1024 Utility Diskette into drive A.
2. Type: A:HOTKEY
A:HOTZOOM
3. Once you have entered a graphics application you may press the
F10 (function) key to invoke the ZOOM program.
NOTE: ZOOM uses the F10 key as the default hotkey to invoke the
program. Some software applications may already use this
key for other purposes. Configure your ZOOM hot key for
another key if F10 conflicts with your software.
