[Scilab-users] Bitmap export

[Calixte Denizet]

Hi Stefan,

Few comments:
i) driver(...);xinit(...);...xend(); implies a vectorial export: all the 
scene is completly drawn vectorialy (so the graphic card driver is not 
implied in the draw)
ii) xs2png(0,...): a memory dump is done and the bitmap is converted 
into PNG. The GC driver is called to retrieve the data and it seems that 
this kind of bug is typical to Ubuntu with free driver... the only 
workaround I know (for the moment ;)) is to switch to the proprietary 
driver.
