[NTG-context] Re: Including SVG manipulating color or rewrite in MP

Thanks a lot. Works for me. Am 12. Dezember 2024 17:43:44 MEZ schrieb Mikael Sundqvist :

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

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?
