I want to use an Atari 520 as a video character (and graphics) generator. I'm envisioning a (small?) word-processing system that would support multiple fonts and point sizes, centering, and justification, combined with animation capabilities (primarily to implement scroll, crawl, blink, and other special effects). Has anybody tried this sort of thing before? Any sources of/references to - bitmap or shape font libraries - fast scan conversion algorithms - spline algorithms - animation languages - people interested in collaborating would be very much appreciated. -- Brian Katzung katzung@i88.isc.com

i have just posted some stuff which may help u. nroff v1.10p4 now generates
vt100-ish escape sequences (eg ESC [ 1 m) which another program i posted
(manpager) reads and uses to change fonts (mono only so far, monospaced
font only so far). check it out. included are a bunch of 8x16 fonts to
replace those in RAM (actually, all i do is change the line A pointer to
the font data). i posted src, so this may get u going. it should appear
soon (i sent it out a week ago). my plans with nroff are to eventually
support proportional fonts (for laser printers and the screen) so that
it will be more troff than nroff (for non-unix people, these are batch
oriented text formatting programs under unix).
note that i also posted a bunch of tools to batch edit the .FED fonts
i used, including a program to convert .FNT files (which come with MGR)
into .FED files (which is the format used by TOS).
you can also consider GDOS, though i have no experience with it.
