<p>Hi all,</p>
<p>xs2svg is not working well with big grayplots: the resulting svg
file is too big and contains too many elements to be usable.
Worse, for really big grayplots, the export fails (not enought
memory).<br>
</p>
<p>As an example, the following code:<br>
grayplot()<br>
h=gcf();<br>
xs2svg(h,'grayplot.svg');<br>
results in a 3.7MB svg file with 93784 elements that cannot be
edited with Inkscape.<br>
</p>
<p>The issue is that xs2svg renders each patch of the grayplot using
two svg filled triangles.<br>
In <span class="quote">"he who must not be named"</span>¹, the
svg export is using a more pragmatic approach: everything is
rendered as svg path/text/whatever, except from the intensity maps
(grayplots, surf, ...) that are rendered as bmp and included in
the svg file.<br>
This way, the svg file is really light, can be tweaked with any
svg compliant software (inkscape) and the result is really good.<br>
In practice, to get publication-quality grayplots, I tend to do
the following:<br>
-hide the grayplot, keep all the rest, export to svg,<br>
-hide everything but the grayplot, export to png,<br>
-use inkscape to include the png of the grayplot and hand-place it
in the svg.</p>
<p>Could xs2svg be modified to implement this approach automatically
(maybe using an optional parameter)?<br>
Could this be the basis for a SEP?</p>
<p>Thanks for you feedback,<br>
</p>
