Alignment problem with labels and textext

Alignment problem with labels and textext

[Lutz Haseloff]

[-- Attachment #1.1: Type: text/plain, Size: 985 bytes --]

Hi Hans, hi all,

with the most recent ConTeXt
(This is LuaTeX, Version beta-0.75.0-2013021110 (rev 4576)
ConTeXt  ver: 2013.02.05 22:32 MKIV  fmt: 2013.2.11  int: english/english)
there is an alignment problem with labels using textext.
Labels without textext work ok.

Small example showing the problem:

---------------------------------
\starttext
\startMPpage
pickup pencircle scaled 1mm ;
path p ; p := fullcircle scaled 3cm ;
draw p withcolor .625yellow ;
label.rt (textext("right") , point 0 of p) ;
label.top (textext("top") , point 2 of p) ;
label.lft (textext("left") , point 4 of p) ;
label.bot (textext("bottom") , point 6 of p) ;
\stopMPpage
\startMPpage
pickup pencircle scaled 1mm ;
path p ; p := fullcircle scaled 3cm ;
draw p withcolor .625yellow ;
label.rt ("right" , point 0 of p) ;
label.top ("top" , point 2 of p) ;
label.lft ("left" , point 4 of p) ;
label.bot ("bottom" , point 6 of p) ;
\stopMPpage
\stoptext
---------------------------------

Greetings

Lutz

Looks OK with

Hi Lutz,

With
This is LuaTeX, Version beta-0.74.0-2012122517 (rev 4541) 
ConTeXt  ver: 2013.02.05 22:32 MKIV  fmt: 2013.2.9  int: english/english

Things look fine. Actually, without textext the left and right seem to be aligned 
on the baseline. Where with textext it is aligned in the middle of the text, which
I find to be the correct way. 

regards
	Keith

Re: Alignment problem with labels and textext

Hi Keith,

following testfile perhaps describes my problem better:

\starttext
\startMPpage
drawdot (origin);
label.rt (textext("right") , origin) ;
label.top (textext("top") , origin) ;
label.lft (textext("left") , origin) ;
label.bot (textext("bottom") , origin) ;
\stopMPpage
\stoptext

If i run it by texexec(mkii), all is ok, with context(mkiv) the labels
overlap.

I try to add the problematic mkiv pdf.

Greetings Lutz

I do not know what you expect exactly.
Each textext() label has a bounding box.
This bounding box is then aligned in the case of rt, top, lft, bot
with its appropriate edge centered at the origin.
The lft and rt text thus will not have their baselines aligned, unless you add a \strut.

(This is an issue with the chemical macros.)

Try label.rt (texttext("\strut right"), origin) ;

By the way, you can use:
	draw textext.rt ("\strut right") ;
	draw textext.top("\strut top") ;
	draw textext.lft("\strut left") ;
	draw textext.bot("\strut bottom") ;
which gives a tighter fit than label().



Alan

Hi Lutz,

Just updated, to make sure I have the latest.

I see the problems. 
	top & bottom labels are not centered correctly
	bottom label not low enough
	left and right labels are not aligned at the same height

Sorry, no ansers.

regards
	Keith.

It seems to me, that the label.xx mechanism is completely broken.
the results of label, label.rt and label.lft are exactly the same if i set
labeloffset := 0bp ;
(default is 3bp)

It seems, that my ConTeXt installation was broken in this point.
A complete new installation of the standalone heped.
Sorry for the noise.
