replace chapter text by an image, possible ?

replace chapter text by an image, possible ?

[VnPenguin]

Hi all,
I would like to know if it's possible to replace the chapter text by an image ?
How to do that ? And in this case, how to insert a normal text into
TOC manually in order to have a normal TOC.

Thank you in advance,
Regards,

thanks for asking a simple question -)

\useexternalfigure[chapter-1][cow.pdf]
\useexternalfigure[chapter-2][hacker.jpg]

\setuphead
   [chapter]
   [command=\MyChapterCommand]

\def\MyChapterCommand#1#2%
   {\externalfigure[chapter-\currentheadnumber][height=5cm]}

\starttext

\chapter{One}
\chapter{Two}

\stoptext

this solution looks wiki-able to me, so ...

Hans

Your code works fine. However when I try to add TOC:

\chapter{One}
\section{One-1}

\chapter{Two}
\section{Two-1}

\setuplist [chapter][before=\blank, after=\blank,
style={\switchtobodyfont[20pt]\bf}]
\setuplist [section][margin=2em, width=3em]
\setuplist [chapter,section][interaction=all]
\setupcombinedlist
       [content]
       [alternative=c, aligntitle=no, width=2em]

\placelist[chapter,section]

In the TOC result, there are ONLY item for section. You see, this
question is not simple at all :)

Thank you,

I don't know the mechanisms behind the scenes, but I suppose that you 
override placing the chapter in TOC if you make your own 
"command=\MyChapterCommand".

(Line 2034 in core-sec.tex is \c!command=\@@placehead. Is this one 
perhaps responsible for the strange behavior?)

However this solves the problem:


\setuphead
    [chapter]
    [textcommand=\MyChapterTextCommand,
     numbercommand=\MyChapterNumberCommand]

\def\MyChapterNumberCommand#1{} % hide chapter number

\def\MyChapterTextCommand#1%
    {\externalfigure[chapter-\currentheadnumber][height=5cm]}
