Background placement

Background placement

[nico]

Hello,

The placement of backgrounded text is sometimes unexpected: it forces a  
page break even if there's much room in the page to put the whole thing.  
Searching in the mailing list I've found one thread about the subject  
(http://archive.contextgarden.net/message/20051205.090518.90cc69d4.en.html),  
but playing with \setupinterlinespace as suggested doesn't help.

The problem often occurs just after a heading starting at the top of a  
page (section, enumeration title). Here is an example showing the  
behaviour:

\setuplayout[middle]
\setupcolors[state=start]

% Background
\definecolor[ScreenGray][s=.95]
\setupbackground
   [background=screen,
    frame=on,
    strut=yes,
    width=broad,
    before=\blank,
    after=\blank,
    framecolor=ScreenGray,
    align=right]

% Verbatim environment for programlisting
\definetyping[programlisting]

\setuptyping[programlisting]
             [bodyfont=small,
              before={\startbackground},
              after={\stopbackground}]

\starttext

\input tufte

\input tufte

\input tufte
\input tufte
\input tufte

\section{joke}
Here is an example:

\startprogramlisting
Some code
\stopprogramlisting

And the text continues...

\stoptext

BG

I had a similar problem in the past, and Hans suggested to use 
starttextbackground instead of background. background is supposed to be 
deprecated.

Try the following code and see if you get what you want.

setuplayout[middle]
\setupcolors[state=start]

\definecolor[ScreenGray][s=0.95]

\definetextbackground[listing]
    [backgrond=screen,
     frame=on,
     strut=yes,
     width=broad,
     location=paragraph,
     framecolor=ScreenGray,
     align=right]

\definetyping[programlisting]

\setuptyping[programlisting]
    [bodyfont=small,
     before={\starttextbackground[listing]},
     after={\stoptextbackground}]

\starttext

\input tufte

\input tufte

\input tufte
\input tufte
\input tufte

\startprogramlisting
Some code
\stopprogramlisting

and the text continues ....


\stoptext

Deprecated? Really?

Yes, thanks, it works (this time I haven't the weird behaviour I had some  
time ago with textbackground... strange). But it's time consuming and  
looks then as an overkill solution. To build a 400p book (on a slow  
machine, it's true):

- It takes 396s with background,
- It takes 539s with textbackground, and I've 260 MP graph files generated!
