Textbackgrounds

Textbackgrounds

[Andreas Harder]

Hi all,

I've played with text backgrounds. Please have a look at the following example.

\definetextbackground
  [test]
  [location=paragraph,
   % frame=off,  % -> no round corners anymore
   corner=round, % -> corner=1|2|3… would be nice
   leftoffset=.5\bodyfontsize,
   rightoffset=.5\bodyfontsize,
   topoffset=.5\bodyfontsize,
   bottomoffset=.5\bodyfontsize]

\setuphead
  [subject]
  [after=,
   command=\MyHead]

\def\MyHead#1#2%
  {\framed
    [background=color,
     backgroundcolor=gray,
     frame=off,
     offset=.5\bodyfontsize,
     corner=3]{#1#2}}

\starttext
\subject{Test}
\starttest
  \input tufte
\stoptest
\stoptext

There is a nasty little space between the two backgrounds. How can I avoid it? Further the left borders of the frame are not aligned.

I appreciate your help.

	Andreas

Thank you Hans, that killed the space.

Something is now broken with textbackgrounds :

textbackground has been rewritten.
Perhaps I have missed something, but how can I highlight/grey-out
running paragraphs? The following minimal example worked before...

Alan


\definetextbackground [ongray]
	[location=paragraph,background=color,backgroundcolor=middlegray]

\starttext

\input ward

\startongray \input tufte \stopongray

\input knuth

\stoptext

no, for the moment this is a pretty low level command; however (look in 
core-pos) you can set some MP variables if needed

textbackgrounds

[Patrick Gundlach]

Dear ConTeXt users,

i have a question about textbackgrounds. Is there 

a) something like \setuptextbackground[all][frame=on,...]
   that sets frame=on for all the textbackgrounds out there? 

Or better:

b) is there any way to inherit parameters?
   \definetextbackground[A][frame=off]
    \definetextbackground[B][A] 

    so that B also has frame=off set?

Patrick
