Dos graphics package

Dos graphics package

[Henrik Karlsson]

I have been looking for a Ada package that could draw SVGA graphics on 
a PC. I have not found anything (looked on www.adahome.com, searched with 
altavista etc). But i ahve found a C libarary (Allegro) that seems preatty 
good. Does it exist an Ada binding (thick or thin) to Allegro?

I posted an Ada 83 package for VESA SVGA graphics on RR's BBS and on
Compuserve.  On CIS search for "TGAVESA", as I recall (it's posted under
the moderator's name).

If you are looking for just VGA for use with GNAT/DOS, EZ2LOAD comes with
such a package. I also wrote an experimental SVGA package for it, check
my homepage www.pi.net/~dijklibo.

As far as a binding to allegro is concerned, I did some work on this, but
getting this working is not very easy, as there is a lot of low level stuff
to take into account.

I have also been working on a VESA 2.0 (prot.mode) SVGA package, after
getting VESA to give me access to the full spec, however, I'm not sure
there is sufficient interest in DOS left to publish it.
