[Scilab-users] Bitmap export

[Stefan Du Rietz]

Hi Calixte,
thank you very much for your comprehensive reply! Now I understand why 
I must either install the proprietary driver (beware!) or use the 
vectorial export. I will probably choose the latter when I want to 
export a figure to be able to use it at my web site.

Best regards
Stefan
