Sure, is needed. Checked it again.
I define \scalesetting as
\edef\scalesetting{scale=\xmlattdef{#1}{scale}{1000}}
But I am not sure why this needs the expansion..

The enclosing \rotate[rotation=\xmlattdef{#1}{rotation}{0}]{...} does 
not need the\expanded.



The exapnsion is need for this part only:

\scale[\scalesetting]

ConTeXt checks if the argument contains an assignment which isn't the 
case unless you expand \scalesetting and it sees the = in the argument.

Messed up the order things:

Was:
\scale[\scalesetting]{%
   \expanded{\useMPgraphic{\xmlatt{#1}{name}}{\xmlatt{#1}{parameters%

And of course had to be:
\expanded{\scale[\scalesetting]{%
   \useMPgraphic{\xmlatt{#1}{name}}{\xmlatt{#1}{parameters%

is the \expanded really needed?

Re: [NTG-context] How to box \useMPgraphic?

[Oliver Buerschaper]

 I'd like to insert a little MetaPost square into the running text and
 properly align it vertically. So I tried:

 ---

 \startuseMPgraphic{square}
 draw unitsquare scaled StrutHeight;
 \stopuseMPgraphic

 \starttext

 I want a square \raisebox{-\strutdepth}{\useMPgraphic{square}} in my
 running text.

 \stoptext

 ---

 Unfortunately, to no avail. TeX seems to be asking for some boxed
 content, so I tried to wrap the figure inclusion into a box:
 \hbox{\useMPgraphic{square}}. It doesn't solve the problem either.

 \inframed[frame=off]{\useMPgraphic{square}}

Thanks!

So is this the preferred command for all (horizontal) boxing related  
tasks in ConTeXt (over hbox)?

[NTG-context] Recomputing useMPgraphic in footers

[David Antos]

Hello,

I have

\defineoverlay[Wave][\useMPgraphic{Wave}]

\startuseMPgraphic{Wave}
...
\stopuseMPgraphic

\setupbackgrounds[footer][text][background={Wave}]

The problem is that the graphics is not re-computed on every page,
although I pretty convinced it should.

On the opposite, when I set
\setupbackgrounds[text][text][background={Wave}]
it works perfectly well. (The difference is in [footer] vs. [text].)

An ugly workaround is to call \setupbackgrounds on every page, but it's
not nice at all. What went wrong?

Thanks,
D.A.

as already mentioned (by taco): \setupbackgrounds[state=repeat]
only page and text area backgrounds are recalculated each page (otherwise the 
speed penalty is too big]

an option is to do something:
\setupbackgrounds[page][background=PageBackground]
\defineoverlay[PageBackground][\reuseMPgraphic{PageBackground}]
\startreusableMPgraphic{PageBackground}
  StartPage ;
fill Field[Text][Footer] withcolor red ;
  StopPage ;
\stopreusableMPgraphic
(see metafun manual for details on the page stuff)

(* Please excuse my poor english *)
Semicolon usage in btex ... etex seems weird to me. Can you help me ?
The following source don't produce the expected result :

dotlabel.top(btex 2;3 etex, (0,0)) ;
\stopuseMPgraphic

%-
But the following is ok :
%-- OK
\startuseMPgraphic{test}

dotlabel.top(btex 2,3 etex, (0,0)) ;
\stopuseMPgraphic
\starttext
\midaligned{\useMPgraphic{test}}

I have the same problem withbtex $2;3$ etex
Thank you for any help,

Hi there,

Weird, I thought this was fixed in 1999 somewhere?

Anyway, try adding 

\longMPlinestrue

in your preamble.
