Yes, with lmtx it works but there is no image in the resulting file.

That's because it's LMTX only (the "lmt" prefix of "lmt_svg" should

You find documentation about that in LMTX docs, luametafun.pdf, chapter

Use double quotes:
export OSFONTDIR="/usr/share/fonts/;$HOME/.fonts"

P.S. You may be interested to read bash scripting guide, but in short the
semicolon is used in shell (bash, zsh) to separate two or more commands in a
row, so your line was interpreted by a shell (I assume that it is bash) like
1 command: export OSFONTDIR=/usr/share/fonts
2 command: $HOME/.fonts
so indeed the $HOME/.fonts is a directory.

It relates to a recent thread in the mailing list about color management.
It's an attempt to use inkscape-made SVG graphics inside a CMYK 
workflow, without using color management.


Naturally it would work under some constraints, but there's a lot of 
graphics you can do with Inkscape that falls inside these:
- the number of colors in the input SVG should be limited, so that every 
color gets converted

- no embedded bitmaps, only vector graphics
- perhaps some other constraints on gradients, transparency, etc.

A good alternative would be a remapper based on a custom lua function 
like this:


function rgb2cmyk( r, g, b )
   ...
   return c, m, y, k
end

It's an attempt to use inkscape-made SVG graphics inside a CMYK 
workflow, without using color management.


Naturally it would work under some constraints, but there's a lot of 
graphics you can do with Inkscape that falls inside these:
- the number of colors in the input SVG should be limited, so that every 
color gets converted

- no embedded bitmaps, only vector graphics
- perhaps some other constraints on gradients, transparency, etc.

A good alternative would be a remapper based on a custom lua function 
like this:


function rgb2cmyk( r, g, b )
  ...
  return c, m, y, k
end

Re: [NTG-context] body text invades space for notes

[Philipp A.]

For me it’s even worse (in mkiv), a paragraph of body text completely
overlaps my footnote.

Where are the bottom notes placed? In the footer? Or how does it work? How
to debug it?
