Hi all,
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).
As an example, the following code:
grayplot()
h=gcf();
xs2svg(h,'grayplot.svg');
results in a 3.7MB svg file with 93784 elements that cannot be edited
with Inkscape.
The issue is that xs2svg renders each patch of the grayplot using two
svg filled triangles.
In "he who must not be named"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.
This way, the svg file is really light, can be tweaked with any svg
compliant software (inkscape) and the result is really good.
In practice, to get publication-quality grayplots, I tend to do the
following:
-hide the grayplot, keep all the rest, export to svg,
-hide everything but the grayplot, export to png,
-use inkscape to include the png of the grayplot and hand-place it in
the svg.
Could xs2svg be modified to implement this approach automatically (maybe
using an optional parameter)?
Could this be the basis for a SEP?
Thanks for you feedback,
Antoine
