<p>Hello again,</p>
<p>Just to add to my previous message: increasing nx or ny in my
script can crash scilab during the call to xend().<br>
On my small local machine, this occurs for:<br>
</p>
<blockquote>
<p>nx=4000;<br>
ny=3000;</p>
</blockquote>
<p>for which scilab takes ~7 seconds to create the png in "normal"
mode...</p>
<p>Can any of you confirm this bug?<br>
</p>

<p>Hello all,</p>
In these days of remote working, I need to use again scilab in
headless mode to generate graphics.<br>
<p>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.</p>
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.<br>
<p>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).<br>
<br>
I also have some plots that works without a problem in normal
mode, but fail in headless mode because of some memory
limitation:</p>
<blockquote>
<p>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.<br>
</p>
</blockquote>
<p>Is there a way to get around these problems?</p>
<p>Thanks for your help,<br>
</p>
