Strange StartPage in Metapost

Strange StartPage in Metapost

[Patrick Gundlach]

Hi out there in the deep Cyberscpace ;-),

--------------------------------myfile.tex----------
\%output=pdf
showframe
\setupcolors[state=start]
\setuppapersize[S6][S6]

\startreusableMPgraphic{DemoFrame}
StartPage ; 
pickup pencircle scaled 2pt ; 
Field[Text][Text] := Field[Text][Text] enlarged .5cm ;
draw (llcorner Field[Text][Text] -- ulcorner Field[Text][Text]);
StopPage ;
\stopreusableMPgraphic

\defineoverlay[DemoFrame]{\reuseMPgraphic{DemoFrame}}
%\setupbackgrounds[page][background=DemoFrame]

\starttext
\dorecurse{10}{\input tufte \par}
\stoptext
------------------------------end----------

when I texexec this, I get strange results.
In my opinion, only the \input tufte should be typeset (and, of course the 
\showframe). But as you might see, the DemoFrame also gets typeset. But I 
did not connect  the overlay to the background. Only when I comment out the 
line with \defineoverlay, the mpgraphic is not drawn. So there are two 
problems here:

1) why is this graphic drawn (even though I have not put it in the 
background)?
2) why is this placed on an incorrect place? (It seems that the page starts 
at the upper left corner of the text field, so the vertical line is shifted 
to the right and down.)

Hello Patrick,

I ran your file on my pc and first of all the \%output=pdf line didn't seem
to work unless I changed it into
\setupoutput[pdftex]

Then, why is there ny \ before "showframe" in your file?

I can't "read" the MPost commands so I can't figure out what you expected to
see but I only get a thick vertical line on page 1 which is not there on
page 2. Uncommenting the
> %\setupbackgrounds[page][background=DemoFrame]
does nothing.

One question: I often see reference to "\input tufte" in mails and in some
context files, but I don't have a file by that name on my pc. Is it
something I should have of fill myself with random test lines?

Groet!  Frans

that was a copy and paste error ;-) 

it should say:

%output=pdf
\showframe

this line should be on the left edge of the text area.  And it should not 
appear with the above line commented.

in the new context versions there is a file called tufte.tex:

pg@levana:/opt/context$ find . -name tufte.tex
./2001.07.02/texmf/tex/context/sample/tufte.tex
./2001.07.11/texmf/tex/context/sample/tufte.tex

and also these files:
douglas.tex  knuth.tex  materie.tex  reich.tex  tufte.tex  zapf.tex

Ah, I'll do some copy-and-paste below, see if it works at your place.

That's weird. Maybe you could make that line using \hrule and place it as a
logo. But Hans will probably see what's wrong in your file.

> in the new context versions there is a file called tufte.tex:

I'll download that sometime and just take out the tufte and other test text
files. Right now, my ConTeXt runs fine so I hesitate to experiment too much
by updating it all.

While re-making my own letterhead to work with ConTeXt, I enjoy more freedom
and I changed the logo. I kerned my initials fg to look like a logo ligature
and I wrapped that with a MetaFun line that gets randomized. Lots of fun,
now every one of my letters has a wild new logo line around the fg initials!
Sometimes it's like a big sloppy garbage bag around the initials, then it's
a highly artistic type of flag or the outlines of a continent... fun!

you got me for a moment:

the last {} should be []

now, context silently recovers from a missing second arg and teh reusable 
graphic ends up on the page as expected [in the main text flow]

But why is the graphic not as large as the page part "text"
  Field[Text][Text]
?

Hallo Uwe,

you have seen the line with:

Field[Text][Text] := Field[Text][Text] enlarged .5cm ;

??? Remove it and try again. Still not the same size? Here, it is the same 
as the border shown in \showframe.

so, what it shows is a vertical line, which is what i expect

[beware for double sided texts, since there the backgrounds differ, there 
you can use [leftpage] and [right[age] backgrounds with their successive 
reusable graphics.

The original posting has a typo in this line that results in the use of 
"DemoFrame" instead of defining an overlay:
  \defineoverlay[DemoFrame]{\reuseMPgraphic{DemoFrame}}

And with this (wrong) line, the graphic doesn't has the height of the text 
field -- thus my question about the size.  But now I know that the line
  Field[Text][Text] := Field[Text][Text] enlarged .5cm ;
is wrong and doesn't do what I (and Patrick I suppose) thought it does ...
