- ZOOMACC
- -------
-
- This accessory opens a window on your screen which zooms the pixels around
- your mouse by 8 times. As long as the zoom window is topped, the zoom view
- will change as the mouse is moved. The zooming is as fast as I could make it,
- but improvements could probably be made. It's as fast as I need it, anyway.
-
- The program was written with Lattice C V5.06.02, and comes in two guises:
- one (the normal) is an accessory, the other can be run as either a GEM program
- or as an accessory if you feel that way inclined. It is written in C with some
- small assembler routines for speed.
-
- Limitations: only works on monochrome screens, but will probably work on large
- (A3) screens OK as the screen size is not hard-wired into the code, but is
- obtained from the Line A structure. If you try to run on a colour screen, the
- accessory will not install (an error message is given) and will lie dormant in
- memory. Sorry about this, but I don't have a colour monitor to debug the code
- on.
