[Scilab-users] Exporting graphics as non pink jpg with xinit/xend

[Jens Simon Strom]

Thanks Rafael,
That /is/ a working solution!  However it introduces further complexity 
and computation time rises from n to n*n/2. In my project I have 
hundreds of files to produce an animation,  and the one command 
'plot(x,y(j,:));' in the minimal snippet represents about successive 10 
plots in my project. I consider to go back to the flawless pdf export 
and to look for a conversion tool pdf2jpg supporting batch conversions.
Regards
Jens
