strange behaviour with \scale

strange behaviour with \scale

[Peter Münster]

Hello,

could anybody explain, why the "DRAFT" is bigger on the last two pages
please?

\defineoverlay[Draft][{\scale[factor=max]{\rotate[rotation=60]{~DRAFT~}}}]
\setupbackgrounds[page][background=Draft]
\starttext
\starttables[|l|]
\dorecurse{200}{\NC hallo \NC\AR}
\stoptables
\stoptext

Cheers and TIA, Peter

I played with

\defineoverlay[Draft][{\scale[factor=max]
{\rotate[rotation=60]{\framed[strut=no,offset=0pt]{\strut~DRAFT~\strut}}}}]
\setupbackgrounds[page][background=Draft]
\showstruts
\starttext
\dorecurse{400}{hallo \crlf}
\starttables[|l|]
\dorecurse{200}{\NC hallo \NC\AR}
\stoptables
\showlayout
\stoptext

>From the page where \starttables start till the prelast page where the
"tables" stop, '~' is "squeezed" somehow. There's also no \strut
present in that lines if you take a closer look. I don't have a clue,
but you have good imagination!

If you need a solution: use {\ Draft\ }
If you need the reason: wait for the expert(s)

Thanks a lot! I didn't think about this kind of space at all...

I don't need it, but it would certainly be interesting ;)

 From looking at it quickly, it seems sometimes the output routine
is called when the ~ command has the 'normal' definition, and
sometimes when it has TaBlE's definition. These do not produce
identical results (~ in TaBlE has the width of a 'zero' digit).

I'm not sure why this happens, though.

the meaning of ~ chances inside a table and the last pages are flushed when the 
table is already typeset; a solution is:

\let\normalactivetilde~
\let\normalactivebar  |

\appendtoks\let~\normalactivetilde\to\everypagebody
\appendtoks\let|\normalactivebar  \to\everypagebody

another solution is to set the meaning of ~ at the table cell level; you may add 
that to the wiki as a feature reaquest -)
