Hi,
I uploaded a new lmtx. This time some work has been done at the metafun end.
At the tex end we're working on some overload protection mechanism which
involves tagging many macro so that will take a while (most tagging is
done but checking left over cases take time).
So, I wondered if we
back in the day, I would never try to use fonts
for "drawing". Especially, math fonts, where every designer has a different
idea of what the shape should look like.

Maybe it is safer for me to call it something like « dotshapelabel » ?
In general, I agree. Redefining internal macros has the advantage that your
code doesn't have to change. See, for example:

Hi Aditya,
Thank you very much !
That's great indeed, you gave me an elegant solution.
One more question, in order for me to understand a little more: when defining a
new dotlabel as you do, might it not conflict with the internal definitions of
dotlabel in Metafun in some other place?
Maybe

The shortened operation is the solution ! See MetaFun manual section 1.18
\starttext
\startMPpage
z1 = (1cm,3cm) ;
z2 = (5cm, 9cm) ;
draw (z1--z2) shortened -1
both the end points of this segment
(that is in this example, a point before z1 and a point after z2 on the
straight line) .
Indeed it is possible to write the equation of the line and then compute by
hand the coordinates of the new end points, but I think there is a simpler way
in Metafun to do
Thanks Taco!
I understand much better now. I think it's best to leave the units out
until the drawing stage as you suggest.
Thanks again

As I only use one transparency method anyway I could also fix this by passing a
numeric instead of a pair and use the standard withtransparency (I don’t like
overriding a standard MetaFun method, one never knows what might break in

Hi,
Using multiple (text ) arguments in macros doesn’t work, you would
need to convert all but the last argument into (expr ) somehow.
That means that you probably cannot do a call like the one below at all.

Hi Aditya,
Following your explanations in
