In fact the restriction to 50 colors was a test to understand color
tables. Now I use 250 colors. Of course the rendering on my display is
much better, but I still have a problem of pixel size on postscript.
On display or on PNG I don't see any pixel, whereas I have big squares
on Postscript.
Cheers,
Clement
