SVG not rendering correctly with LMTX and conversion=mp
The following MWE fails to render the text in the attached SVG properly: \starttext \externalfigure[test.svg][conversion=mp] \stoptext The axis labels, tick labels, and title are all incorrect. This file was generated with Matplotlib.
Check that your Inkscape is working properly. That proble NOT appear on my machine... Best, L. Montgomery El lun., 18 de octubre de 2021 10:15, Jason Ross via ntg-context < ntg-context@ntg.nl> escribió:

(Sorry Luis, I forgot to cc mailing list) Per https://wiki.contextgarden.net/Command/externalfigure, in LMTX the conversion is done natively when "conversion=mp" is set. Inkscape is not used for the conversion.
In my tests, this conversion works internally with linux.
On windows it fails and stops at
l.63 \ registerctxluafile {data-bin} {}
% before data-tex
?

If you open test.svg with Inkscape, ungroup and then save, you get a SVG that is typeset right with LMTX. Looking at the differences between the two SVGs, I can see that Inkscape changes all the transform="translate(...)scale(...)" attributes into transform="matrix(...)". Now focus on the "y = sin(x)" text. In the attachment I modified the transform attributes of that text, from "translate(...)scale(...)" to "matrix(...)", taking the values from the version obtained from Inkscape. Use that SVG with your MWE and you'll see "y = sin(x)" appearing in the right place in the PDF. I would say the "translate(...)scale(...)" specification is not supported in LMTX (yet). Massi

Coming soon... (see attachment) The problem was the order in which transformations are applied when multiple transformations are specified in the transform attribute, like in "translate(...)scale(...)...". testsvg.tex and test.svg are the MWE and the SVG file provided by Jason Ross in the first post of this thread.

I would say the "translate(...)scale(...)" specification is not supported in LMTX (yet). does the spec say anywhere what teh order is?
<!-- g transform="translate (14.118498 132.66443) rotate (-90) scale (0.1 -0.1)" --> this looks better but <g transform="scale (0.1 -0.1) rotate (-90) translate (14.118498 132.66443) "> how about 10 scales and 15 rotations and 3 transforms in any order?

The axis labels, tick labels, and title are all incorrect. This file was generated with Matplotlib. we actually can avoid that by using label remapping (i fixed a scanning buglet in the first example:)
\startTEXpage \startMPcode lmt_remaptext [ label = "here 1", where = "l", text = "\bfa let's try this one out" ] ; lmt_remaptext [ label = "here 2", where = "r", text = "let's try this one out too" ] ; lmt_remaptext [ label = "here 3", where = "l", text = "$e = mc^2$" ] ; lmt_remaptext [ label = "here 5", where = "m", text = "this a bit longer label" ] ; lmt_remaptext [ label = "here 4", where = "m", text = "!", dx = -1pt, dy = -30pt ] ; draw lmt_svg [ filename = "labels-003.svg", ] ; \stopMPcode \stopTEXpage one can also have the labels externally \startluacode table.save ( "labels-001.lua", { { label = "here 1", where = "l", text = "let's try this one out" }, { label = "here 2", where = "r", text = "let's try this one out too" }, { label = "here 3", where = "l", text = "$e = mc^2$" }, { label = "here 5", where = "m", text = "this a bit longer label" }, { label = "here 4", where = "m", text = "!" }, } ) \stopluacode \startMPpage draw lmt_svg [ filename = "labels-003.svg", labelfile = "labels-001.lua", ] ; \stopMPpage the idea is then that in an svg editor one uses symbolic names and when including those get property typeset (should work in in next upload; is independent of reported issue) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
