- GMOVIE is written in TURBOC 2.0. The original data was in the
- form of 30 frames each consisting of one bit per pixel. Each frame
- being 256 X 256 pixels. Since pixels aren't square on IBM
- displays, I drew 5 pixels for every 4 in the data file to create
- the illusion of a round Earth. Each frame was drawn a pixel at
- a time and taken from the screen using the GETIMAGE function, then
- written the the file GMOVIE.DAT. GMOVIE.EXE simply reads one image
- from GMOVIE.DAT and displays it using the PUTIMAGE function. To
- achieve smooth rotation of the Earth I draw the image to an EGA
- display other than the current visual display and when complete
- make that display the visual display.
