Dear all,
I have near to zero knowledge about MPgraphics, so I always use SVG
files from various sources.
I do something like this:
\defineoverlay[pic][\externalfigure[form.svg][width=14em]]
\defineframed
[textcircledA]
[
frame=off,
strut=yes,
rulethickness=0.0pt,
background=pic,
location=top,]
\textcircledA{\externalfigure[icon.svg][width=280px]}
The form.svg appears as background of icon.svg.
Now I want to change the stroke color in the svg.
It is very simple:
<?xml version="1.0" encoding="UTF-8"?>
<!-- Created with Inkscape (http://www.inkscape.org/) -->
<svg width="20.887mm" height="17.613mm" version="1.1" viewBox="0 0
20.887 17.613" xmlns="http://www.w3.org/2000/svg";>
<g transform="translate(152.66 -101.94)">
<path d="m-150.94 114.93c-0.5424-1.3121-0.58209-2.9382 0.18256-5.2163
2.3566-7.0175 11.139-8.7098 15.878-3.0594 7.6978 8.7032-11.506
16.052-16.06 8.2756" fill="none" stroke="#99bcdb" stroke-linecap="round"
stroke-width="2"/>
</g>
</svg>
I can simply open it in inkscape set the color an save it under a
meaningful filename, but I would like to set the color in the context file.
I tried to define the overlay pic with \includesvgbuffer but I can't get
it to work.
\startbuffer[svg]
<svg width="20.887mm" height="17.613mm" version="1.1" viewBox="0 0
20.887 17.613" xmlns="http://www.w3.org/2000/svg";>
<g transform="translate(152.66 -101.94)">
<path d="m-150.94 114.93c-0.5424-1.3121-0.58209-2.9382 0.18256-5.2163
2.3566-7.0175 11.139-8.7098 15.878-3.0594 7.6978 8.7032-11.506
16.052-16.06 8.2756" fill="none" stroke="MyColor" stroke-linecap="round"
stroke-width="2"/>
</g>
</svg>
\stopbuffer
\defineoverlay[pic][\includesvgbuffer[svg][offset=1bp]]
Nothing happens, no form appears in the overlay.
I saw an example with \startstopuseMPgraphic in the Wiki.
\startuseMPgraphic{MPtextcircle}
path p;
p := fullcircle xscaled OverlayWidth
yscaled OverlayWidth;
setbounds currentpicture to p ;
% p:= p shifted (0,StrutDepth/2.7);
draw p withpen pencircle scaled 25pt
withcolor OverlayLineColor;
\stopuseMPgraphic
\defineoverlay[OLtextcircle][\useMPgraphic{MPtextcircle}]
This works for me.
Is it possible to use a svgbuffer in a overlay definition?
Or do I have to convert the SVG code to MP?
Is there a converter?
TIA
juh
