That's the very first thing we change after installing scilab on all the computers in our group, so I agree we need to change it. Is there a way to make people aware of this settings and tell them that it's related to plotting? Like displaying a tip saying that they can crank it up when they need to display/export large plots and that it will add up to the memory used by scilab?

Hello again,

Just to add to my previous message: increasing nx or ny in my script can crash scilab during the call to xend().
On my small local machine, this occurs for:

    nx=4000;
    ny=3000;

for which scilab takes ~7 seconds to create the png in "normal" mode...

Can any of you confirm this bug?


The crash is due to a too small Java Heap of memory.
When increasing it through the user's Preferences from 256 MB to 1 GB, the PNG export works as fast as expected.

By the way, everyone, what do you think about increasing the default Scilab java Heap from 256 MB to 512 MB? This default 256 MB was set a long time ago, when on computers the average RAM what much smaller than today...

Samuel
