Dear Henri Menke,

I always use “btex etex” for labeling math.
But “…..” is simpler and it works fine.

Thank you.

Best regards,

Dalyoung

Sometimes, one might want to use btex ... etex to produce a picture object, for example:

label.lft(btex $\delta$ etex rotated 90, frame) ;



A few notes:

1) Hans has recently rewritten btex ... etex so there may be a bug

2) I recently rewrote label to accept a closed path or a picture in addition to a location (a pair), in which case it places the label relative to the bounding box (by default, at the center). I illustrate this above above.

Why not just

label.bot("$\delta$", (3cm,0));

labeling in meta post

[Jeong Dal]

Hi,

What is the difference between {\delta} and \delta?
Former is OK, but the second is not compiled.

Here is a MWE.


\startbuffer[delta]
label.bot(btex ${\delta}$ etex, (1cm,0));	%
%label.bot(btex $\delta$ etex, (3cm,0));
label.bot(btex $\frac{2-\delta}{2}$ etex, (5cm,0));	%
\stopbuffer
\starttext
\processMPbuffer[delta]
\stoptext

Best regards,

Dalyoung
