You could just use a framed.

indeed, the lmtx definiton sis similar:

[NTG-context] Auto width and height on table cells
Hello, I want some tables to occupy 100% of \textwidth and \textheight and for all columns to be the same width except one or two that I want to specify and for all rows to be the same height except for one or two, that I want to specify as well.. For the moment, I'm doing it "manually", calculating column width as (\textwidth - width of fixed columns) / # rest of columns and row height as (\textheight - height of fixed rows) / # rest of rows I'm getting the result that I want, but it's a bit tedious. Is it possible to have ConTeXt do all those calculations for me? I haven't been able to figure it out from the manuals and the wiki. Thank you in advance.

Re: [NTG-context] SVG text alignment issue
Here's the formal rule: https://www.w3.org/TR/SVG11/coords.html#TransformAttribute rotate( [ ]), which specifies a rotation by degrees about a given point. If optional parameters and are not supplied, the rotation is about the origin of the current user coordinate system. The operation corresponds to the matrix [cos(a) sin(a) -sin(a) cos(a) 0 0]. If optional parameters and are supplied, the rotation is about the point (cx, cy). The operation represents the equivalent of the following specification: translate(, ) rotate() translate(-, -). It looks like cx/cy, if not present, mean to rotate the text about its origin, which I would take to be width/2 and height/2. They define the rotation matrix as [cos(a) sin(a) -sin(a) cos(a) 0 0], where a is the angle: https://www.w3.org/TR/SVG11/coords.html#RotationDefined It appears as though LMTX is rotating around the baseline, rather than the central point of the text's bounding box. (I thought that (cap height + descender height) / 2 was the middle, but I suppose that wouldn't account for diacritics.) Thanks for looking into this!

Re: [NTG-context] SVG text alignment issue
Thanks for checking this. Unfortunately, introducing \hbox didn't work; the
text is still off-center with respect to the vertical line:
https://i.ibb.co/hYGfdgZ/text-align.png
For comparison, the SVG file loaded into Inkscape appears similar to:
https://i.ibb.co/KF3PBkw/inkscape-alignment.png
Note how the text is vertically centered above the vertical line.
To me, it looks like the text, after a rotational transform, is being
written to the baseline rather than (cap height + descender height) / 2,
which seems to be a MetaPost conversion issue? There's another, possibly
related issue, which I'll provide in a separate thread.

[NTG-context] indent in \setuptyping
Dear list,
I have the following sample:

\setuptyping
[align={right,broad},
strip=yes,
lines=yes,
blank=halfline]
\starttext
\startXML
content content content content

content content
\stopXML
\stoptext
Which is the option to have the first contents broken and indented
automatically by ConTeXt?
I have tried all possible options from
https://www.pragma-ade.com/general/qrcs/setup-en.pdf#page=266. I had no
luck.
I remember that this worked (but I couldn’t find the message from Hans
where he added the option [years ago...]).
Many thanks for your help,
Pablo

This has nothing to do with SVG. Looking at the definition of
\includesvgbuffer, here is a simpler example illustrating the issue:
\starttext
\startplacefigure[location=here, title={Test}]
\dontleavehmode\begingroup
\startMPcode
draw fullcircle scaled 2cm;
\stopMPcode\endgroup
\stopplacefigure
\stoptext
One way to "fix" the alignment is to wrap everything in an hbox:
\placefigure[]{}{\hbox{\includesvgbuffer[svg][conversion=mp]}}
Maybe there is a simple way to modify the definition of includesvgbuffer so
that an \hbox is not needed.
