SVG not rendering correctly with LMTX and conversion=mp

SVG not rendering correctly with LMTX and conversion=mp

[Jason Ross via ntg-context]

[-- Attachment #1: Type: text/plain, Size: 239 bytes --]

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...

(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.

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).

In my tests, this conversion works internally with linux.

On windows it fails and stops at

l.63 \ registerctxluafile {data-bin} {}
                                  % before data-tex
?

it is supported; i'll send you a snippet to test (as it was not really a 
minimal example)

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?

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)

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.
