Howdy. This is a program that generates the Mandelbrot set, very quickly.
It works in High and Low resolutions only. The program originally appeared
in the German ST-Magasin, and was sent to me by Claus Priisholm in Denmark
(riddler@iesd.ac.dk). I've taken the liberty of using a resource editor to
translate the menu options to English. The original resource file is also
included in the ARC file.
Since there are no other docs, here's a brief rundown on what the options
do, or as far I was able to determine from playing around...
File
Quit - Obvious.
New - Reset the coordinates to original values
Load - Load an image, DEGAS or Apfelman format
Save - Save image, same choices, I think
Execute - No automatic redraws, you must select this
after changing an option
Parameter
Coordinates - Select the region of the M-set to view
Zoom Box - Use the crosshair to select a region to zoom
Options
Scale - Image size factor, 1-9
Color Bias - Dunno, really. The higher the number,
the fewer colors you get.
Iterations - Controls precision of computations.
Larger numbers give more detail, but
take a lot longer to draw.
Extra
Menu Bar - Turn off menu bar. Enable with a mouse click.
Hardcopy - Print the screen
R,G,B - Mask out a color
Film - Invoke APM_FILM.PRG. You can generate a sequence of
Apfelman format image files, and use them to produce
a sequence of DEGAS image files for blasting or other
viewing purposes. I don't remember what the prompts
mean, oh well.
It's a pretty cute program, though I don't think it really beats out
Fractint. Anyway, enjoy...
