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

Hi,

Not sure exactly what you are after, but this could work (I saved your
svg as juh.svg)

/Mikael

\startuseMPgraphic{juh}{juhcolor}

picture juh ;

juh := lmt_svg [
  filename = "juh.svg",
  origin   = true ] ;

draw juh ysized OverlayHeight withcolor \MPvar{juhcolor} ;

\stopuseMPgraphic

\setupMPvariables[juh][juhcolor=darkred]

\defineoverlay[juh][\useMPgraphic{juh}]

\starttext

\framed[align=normal,width=7cm,background=juh]{\samplefile{ward}}

\setupMPvariables[juh][juhcolor=darkblue]

\framed[align=normal,width=7cm,background=juh]{\samplefile{ward}}

\stoptext
