Ah, depth. You can set the depth and an offset :
\setupbackgrounds[page][offset=3pt] or
\setupbackgrounds[page][depth=4pt]

Ha, if you new all the secret options ... Another nice one is 

\definereference[cool][JS(forgetall),CloseDocument]

.... \goto{Like It Or Not}[cool] ....

once documented, you can also do one-step symbol switching and some
more.

reverse them: 

  \naar{Echte poster}[#1::]

or (\naar{Echte poster}[file(#1)] or [page(file::1)] or whatever looks
best)

Hi all,

Based on Hans's "ConTeXt, an excursion", I've written (rearranged and 
rewritten) a chapter of a book that will be be published soon.
You can get a preview from http://frambach.eco.rug.nl/context.pdf
Any comments on errors or omissions are welcome! Never mind the
details of the layout, first we have to get the content right.

Yep, well, I am using 

\startbackground Some stuff \stopbackground

The backgound crosses the page-size:

+-----------------+  --> text boundary
|                 |
|   +---------+   |  --> Backgound edges
|   |Some text|   |
|   |Some text|   |
|---+_________+---+

The background box is a bit deeper then the page-boundary (Sorry, I 
mean the \zethoogte).

If you need more info, I can send you the resulting .pdf file which 
shows these difficulties (I will not post it on the list). I can also 
send you the style file I use, but it is **very* similar to s-pre-01

This is *very* cool (I don't need it right now, but I'll keep it in 
mind.

The \leavevmode was necessary to make consecutive empty lines show 
up too (normally they are handled like multiple \par, e.g. they are 
changed into a single \par.

Dat komt later. Die #1 wordt later:

  \naar[#1::]{Echter poster}

  where #1.pdf --> poster file of the destination

Because the people who wrote the input file needed some basic formatting 
control (simply some newlines will suffice for them).

\startbackground and verbatims

[Gilbert van den Dobbelsteen]

Hi there,

I am having some difficulties with colored backgrounds and verbatim 
like stuff.

I am sorry, the interface is dutch, so all goreign people will probably 
have some trouble reading the source. 

The trouble is the backgrounds, they seem to go beyond the page 
definition. Is there something I can do about that? Perhaps 
with \startregelcorectie or something like that?

I noticed that behaviour before, but on a A4 page it is usually not a 
problem. But this is a interactive layou, where there is not much space 
available on a page. And since the page has colors too, it is pretty 
obvious that backgrounds go beyond the boundaries.

So please, offend me, I am probably doing everything wrong here.

I also have another problem, with huge butons: I need to create a 
button which is large and contains multiple lines of text (The 
\startposter should do that). I am not very interested in high-lighting 
each word, just highlighting the entire block of text will suffice. Can 
any picture be the background of any macro where achtergrond=xxx is 
available?

%!&cont-nl

% From TeX by Topic:
{\catcode`\^^M=13 %
 \gdef\olines{\catcode`\^^M=13 \def^^M{\par\leavevmode}}%
}

\def\startposter#1{\startachtergrond\bgroup\olines}
\def\stopposter{\egroup\stopachtergrond\blanko[2*groot}

\starttekst

\startposter{external}
Hi there, this is some poster-text
\stopposter

...etcetera (more start/stop poster stuff)

\stoptekst

There are two kinds of backgrounds. When you want a background to a page
are specific area of the page, use \setupbackgrounds. This has nothing
to do with the running text. You can put a background behind text, using
\startbackground etc. This will cross the page boder ok, takes care of
some offsets etc.

How do you mean beyond?

You can set up a screen size.

Probably.

Yes. Even multiples and mixed with color: 

\defineoverlay[one][this is one]
\defineoverlay[two][this is the second one]
\defineoverlay[three][this is the last one] 

\setupcolors[state=start]

\framed[background={color,one,two,three},backgroundcolor=red]{Hi there}

\obeylines will do.

wat doet die #1 daar? 

> \def\stopposter{\egroup\stopachtergrond\blanko[2*groot}

\def\startposter{\startachtergrond\startregels}
\def\stopposter {\stopregels\stopachtergrond}

Why the obeylines?
