Dear list,
I'm trying to make some fancy chapter headers. With MetaPost I drew a
wave, which I'd like to place in the margin. I've read details.pdf and
metafun.pdf, but I don't manage to get the positioning right. The wave
should begin where the bottomframe ends and move on to the page
border. Also, the graphic is placed in the page background layer, but
nevertheless the text after the the graphic is shifted down.
\startuniqueMPgraphic{wave}
numeric periods, width;
path wave;
periods := 3 + 1/4;
width := periods * 2*pi;
wave := origin for x=0 step 0.1 until width:
-- (x,x*sin(x))
endfor;
pickup pencircle scaled 1pt;
draw wave xscaled (OverlayWidth/width) yscaled (OverlayHeight/(2*width));
\stopuniqueMPgraphic
\definelayer[decorations][position=yes,option=test,location=r]
\setupbackgrounds[page][background=decorations]
\defineoverlay[wave][\uniqueMPgraphic{wave}]
\starttext
{\ss\bfc A chapter title}
\blank[small]
\framed[frame=off,bottomframe=on,width=broad,rulethickness=1pt]
{\ss\bfx \date \hfill Author Name}
\setlayer[decorations]{\framed[background=wave,frame=off,width=\cutspace,height=2\lineheight]{}}
\input knuth
\stoptext
What am I doing wrong? Is it a better idea to draw the bottomframe in
MetaPost too? How do I take care of positioning in that case? Absolute
positioning is not an option, because the length of the chapterheads
can be two lines. It should also work on other paper sizes (A5 in
particular).
Kind regards,
Tim Steenvoorden

I have no experience with layers in combination with 'position=yes'. Anyhow, IMO it's much easier to draw all in one graphic than try to attach the MP graphic with the frame(d) border. Also: I have no idea how to do it :-) I attached a working example, but it's more a starting point than a final solution.

You are right it is easier to draw both the wave and the line in Metapost. And the dx=-\cutspace is just what I needed for left pages!

Your problem is that you use {\ss\bfc …} etc. to place the title rather than contexts \title command where you can define your own command. With such a command you can put all text in a frame with your graphic a background. - http://wiki.contextgarden.net/Generate_Authorlist_from_Head_Content - http://wiki.contextgarden.net/Titles#A_complex_graphical_element_under_the_chapter_title Wolfgang ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 6+ messages in thread

I switched to a solution as on the wiki, using overlays and frames in place of layers. After setting the boudingboxes right it works!
