narrowered columns on background image?

narrowered columns on background image?

[Rudolf Bahr]

[-- Attachment #1: Type: text/plain, Size: 1700 bytes --]


Hi All,

in the following two code examples I tried to place text in columns on a background image.
The first example, partly achieved by plain TeX commands is ok, even narrowering works.
Have a look at the attached .pdf file.

The second example isn't ok. Neither narrowering nor putting the text into columns work.
Though the code of the first example is completely good enough for me, I'd like to learn where my 
mistakes in the 2. example are. Any ideas?

Greetings, Rudolf

You have to use boxedcolumns environment because the normal columns environment doesn’t work in a frame.

\setupexternalfigures[location={local,global,default}]

\starttext

\defineoverlay[muh][{\externalfigure[cow][width=\overlaywidth, height=\overlayheight]}]

\startframed[width=max,height=0.4\textheight,background=muh,align=right,foregroundcolor=darkred]%
  \startboxedcolumns[n=3]
  It was a dark and stormy night. The rain came down in tons. The old captain
  said: \quotation{Antonio, come and tell us a story!} And Antonio began as follows:
  \quotation{It was a dark and stormy night. The rain ...}
  \stopboxedcolumns
\stopframed

\stoptext

Yes, that's it, what I didn't know: boxedcolumns. Your example works very well, even with inserted
narrower environment:

\startframed[...]
  \startnarrower
    \startboxedcolumns[n=3]
    ...
    ...
    \stopboxedcolumns
  \stopnarrower
\stopframed

Many thanks, Wolfgang, for your patient explanation! You helped me so many times!

Rudolf

Why do you want to use the narrower environment in a frame, when you want to
change only the left and right margins you can use the loffset and roffset keys.

\starttext

\startframed[align=right,width=max]
  \input knuth
\stopframed

\startframed[align=right,width=max,loffset=2cm,roffset=4cm]
  \input knuth
\stopframed

\stoptext

Ofcourse, you are right, it's better, thank you!
