backgrounds: help needed

backgrounds: help needed

[Peter Münster]

Hello,

I need some text with background, that can break across lines. But the
background must not touch the background of the next line!

\setupcolors[state=start]
\starttext
inframed does not allow linebreaks:

\def\Bla{\inframed[background=color, backgroundcolor=gray, frame=off,
    offset=overlay, backgroundoffset=2pt, location=keep]{%
    FF FF XX XX XX XX XX XX SS CS CS}}
\dorecurse{20}{bla \Bla\ bla}

And textbackground does not allow to seperate the backgrounds of 2 lines:

\definetextbackground[TG][backgroundcolor=gray, frame=off,
  offset=overlay, backgroundoffset=2pt]
\def\Bla{\starttextbackground[TG]FF FF XX XX XX XX XX XX SS CS CS%
  \stoptextbackground}
\dorecurse{20}{bla \Bla\ bla}
\stoptext

Could anybody help please?

TIA for any hints!
Cheer, Peter

Re: backgrounds: help needed

[-- Attachment #1.1: Type: text/plain, Size: 1008 bytes --]

I, too, do not understand the
	\definetextbackground
	\starttextbackground
	\stoptextbackground
commands, even though I tried looking at "details.pdf" (and core-pgr.tex).

My particular problem is rather classic, that of illustrating examples, set off from the main text.
I first used

\defineframedtext [example] 
	[width=fit,background=screen,backgroundscreen=0.7]

\startexample
	...
\stopexample

and this is appropriate if the example is short enough to fit on one page.
However, a long example (many paragraphs) that spans more than one page
runs off the bottom.
Textbackground seems more appropriate, so I tried

\definetextbackground [example] 
	[location=paragraph,backgroundcolor=middlegray,frame=off]
\definestartstop [example] 
	[before={\starttextbackground[example]},after=\stoptextbackground]

but this does not work. I tried other variants (such as adding state=start, ...) with no success.

Does anyone have suggestions on where to look for further documentation or examples of use?
Thanks.

This works for me.

\setupcolors[state=start]

\definetextbackground
   [example]
   [location=paragraph,
    background=color,
    backgroundcolor=middlegray,
    frame=off]

\starttext

\input knuth

\startexample
\dorecurse{4}{\input knuth\par}
\stopexample

\input knuth

\stoptext

This wasn't in the original file and it's possible Cecil enables
color in his default module.

Re: backgrounds: help needed

[Alan BRASLAU]

[-- Attachment #1.1: Type: text/plain, Size: 509 bytes --]

I am still a bit confused about textbackgrounds.
So I created a wiki page http://wiki.contextgarden.net/TextBackground
(in order to try to confuse others!)

I have two questions:
1. The live conTeXt of the wiki does not show the background,
whereas the code works using the context minimals.
Why?

2. Setting background=screen as opposed to background=color,backgroundcolor=middlegray
doesn't work (live & minimals). Why?

Can anyone help here? Beyond details.pdf, I have not found many explanations.

Thanks

Not supported in textbackground, it works only for framed and  
framedtext.

This works for me.

\setupcolors[state=start]

\definetextbackground
   [example]
   [location=paragraph,
    background=color,
    backgroundcolor=middlegray,
    frame=off]

\starttext

\input knuth

\startexample
\dorecurse{4}{\input knuth\par}
\stopexample

\input knuth

\stoptext

Wolfgang



For me this works only with context 2008-10-31.

It doesn't work with the beta from 2008-01-18 (no background).

MkII or MkIV?

Can you try "texexec --make metafun --standalone".

MkII.
I just reinstalled the october version; everything ok.
btw: It seems that it still worked fine with a context-beta from 2008-12-01.

The example works correctly with
ConTeXt  ver: 2009.01.18 14:39 MKIV  fmt: 2009.1.25  int: english/english
as well as with MKII

Thanks for your answer.

I installed the 2009-01-18 yesterday at home on my mac. Everything works
fine!

Now I re-reinstalled the 2009-01-18 on the windows machine at work, and I
get the same result as before: no gray background.
I even did the "texexec --make metafun --standalone" from Wolfgang, but
still no background. 

I noticed that on the win system the <filename>-mpgraph.4000 etc. and
-mpgraph.keep files don't appear at all; they do appear of course with
2008-10-31. Appearently these are holding the code for the background.

Any ideas?

Thanks in advance
Thomas

Finally I've found the problem.

In the cont-sys files from 2009-01-18 the following two lines are enabled:

\runMPgraphicstrue
\runMPTEXgraphicstrue

(in 2008-10-31 they are still outcommented)


But to make this work on windows a few additional steps were necessary:

1. texexec --make --alone metafun (as Wolfgang already mentioned)

2. copy the new metafun.mem from \Documents and
Settings\username\.texlive2008\texmf-var\web2c\ to the 'normal' texmf
directory (\texlive\2008\texmf-var\web2c\metapost).

3. Enable write18 in the texmf.cnf

4. remake the formats
