Re: [NTG-context] Label in externalfigures

13 Feb 2020


      I’ve tested this but it appears outside, not as an layer over the picture.

\startMPcode 
draw lmt_svg [
	filename = "steguppgift.svg",
	height = 5cm,
	width = 10cm,
	] ;
label(\sometxt{5,0m},(63.936298,129.563995));
label(\sometxt{37°},(95.652702,27.367201));	
\stopMPcode

Thanks

The expected output should be like this, see example in the link below

So that I have a picture so I can change the label text inside according to different needs e.g change from 37° to 41° without reediting it in Inkscape.
A similar properties like latex export picture.pdf_tex which is a function in Inkscape
I investigate the details manual tip you provided, thanks a lot.
you might want to peek into the luametafun manual as svg is discussed there, including label stuff
what you can also try (with lmtx) is this (no real interface yet):
\starttext
\hbox\bgroup
 \ctxlua{metapost.startsvghashing()}%
 \includesvgfile[labels-004.svg]%
 \ctxlua{metapost.stopsvghashing()}%
\egroup
\stoptext
which should turn your labels into tex, so you can typeset them as tex (so $\\sin(x)$ comes out as math) it's no big deal to add a remap option there but then i'd rather go for symbolic names
