Hi, Jocelyn,

Scilab is awfully slow for displaying images. I'm thinking about
rewriting some of scilab's graphical functions to speed this process
up, but it will take me a lot of time.

In the meanwhile, You can try this in scilab 2.7:

xset("pixmap",1);   // pixmap mode

imshow(some_image)

xset("wshow")       // shows the pixbuffer in the screen at once

xset("pixmap",0);   // returns to normal mode


My friend which has a windows box is using it, so I won't be able to test that
solution until thursday.

Until then, please tell me if it works for you.
The drawback of this solution is that it may be hard to use subplot,
I think.

You should also post your question to the scilab newsgroup:
comp.soft-sys.math.scilab

hope it helps,
Ricardo.
