[GRASS5] Re: embedding GRASS display into my app

[Stefan Paulick]

Hello David, 

I'm working on a simmilar problem. I try to do content control and 
visualisation from at second PC running Windows2000. This application is 
programmed with Agilent VEE, a programming environment mainly used for 
instrument control but also able to handle most of the other pc stuff. It 
does handle C routines written as a dll very good, but unfortunately it is 
not available for linux. 

Looks to me that grass is grown around the user's keyboard (sorry for that 
if I'm wrong!) so there would be the need for writing a interface both to 
send and collect the grass in/output. I will do that around TCP/IP so I can 
use this functionallity both local and remote on the w2k pc. 

The hint earlier using png output should be perfect for the first shot. 

I never thougth about learning tcltk, because it looks to me that I have to 
built everyting from the scratch which is eating too much time & I'm not 
very fond of learning it, too (Generation M$, grown up with Turbo-Pascal 3 
;_)) ). 

I'm not shure now if my approach is useful, so any comment on this would be 
cordially welcome. 


Mit freundlichen Grüßen / With kindest regards
