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?

Hello all,
In these days of remote working, I need to use again scilab in
headless mode to generate graphics.
In other words, I connect in command line only to a remote server
where scilab is installed and I want it to generate graphics using a
combination of driver, xinit and xend.
There seems to be some issues with driver/xinit/xend: huge memory
overhead and long computation time that makes it impossible to
generate some plots in headless mode.
For example, a simple Sgrayplot that takes ~1 second to plot and save
to a png in normal mode takes more than 200 seconds and huge amount of
ram in headless mode (see attached test script).
I also have some plots that works without a problem in normal mode,
but fail in headless mode because of some memory limitation:
xend: An error occurred: Unable to create export file, not enough
memory. Decreasing the number of elements or the size of the
figure should fix this error.
Is there a way to get around these problems?
Thanks for your help,
Antoine
