Screen background in two columns
Good afternoon. I'm typesetting a document in two columns. I'd like to typeset examples in it just in the rest of the text but with a screen background. I tried this: \setupcolors[state=start] \setupscreens[screen=0.8] \setupbackground [background=screen, leftoffset=1em, rightoffset=1em, topoffset=1em, bottomoffset=1em] \setupframedtexts [frame=off, background=screen, width=fit] But both \startbackground and \startframedtext does not allow column/page break. I want the background to start e.g. on the bottom of the left column and to go to the top of the right one. How can I get what I want? (Well, maybe a hard task in the TeX. Some time ago I would suppose it to be unpossible---but then I've seen such a wizardry in the ConTeXt that made me to think that everything is possible---at least for Mr. Hagen.) :-) Many greetings to all of you. M.K.

I admit that this takes some wizardry to implement, especially if you take into account that backgrounds should work in tables, tabulate, floats, inside and outside text areas, obey indentation, left/rightskip, hanging, nested backgrounds, multiple layers, etc ; this (still somewhat experimental mechanism will be discussed in details.pdf). % output=pdftex \setuplayout [width=middle,height=middle, backspace=1cm,topspace=1cm, header=0pt,footer=0pt,grid=yes] \setuptolerance[verytolerant,stretch] \setupindenting[big] \starttext \definecolumnset[two][n=3] \definecolumnsetspan[test] \definetextbackground[test] [location=paragraph, % text background=color, backgroundcolor=red] \startcolumnset[two] \startcolumnsetspan[test] \input tufte \stopcolumnsetspan \starttextbackground[test] \dorecurse{10}{\input tufte \par} \stoptextbackground \stopcolumnset \stoptext ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

Hm. I thought it's a black magic. Maybe a young Christian boy should abstain of it. :-))))) But seriously, it doesn't work. I can't see any color. Yes, I've add \setupcolors[state=start] and tested it. Where's the bug? And one more question: Can the columns be ballanced? I know some time ago it wasn't possible? Is the ConTeXt wizardry so mighty? With many greetings Michal Kvasnicka

Good evening. Is somewhere any general manual for columnsets? Or some general demo in english interface? I really like the concept but I don't know how to use it. (Moreover, I've all examples Mr. Hagen sent me when my harddisk crashed.) Many thanks and greetings, M.K.

Here is some crude test file with layers and columnsets. Perhaps you find out what you're looking for. I don't really understand it any more... ;-) \definelayer[test] \setupcolors[state=start] %\setupbackgrounds[page][backgroundcolor=yellow,background={color,foregr ound,test}] %\setlayer[test][x=10cm,y=0cm]{\externalfigure[koe]} \setuplayer[test][position=yes] \tracecolumnsettrue \showgrid \starttext \definecolumnset[vier][n=4,distance=6mm] %\definecolumntextarea [two] [right][x=5,y=45,nx=2,ny=18,state=start] %\setupcolumntextareatext [two] [right][{\externalfigure[koe][width=\hsize]}] \startcolumnset[vier] \input tufte \placefigure[tblr]{}{} \input zapf \input tufte \placefigure[btrl:3]{}{\framed{test}} \input zapf \input tufte \input zapf \input tufte \placefigure[tblr]{}{} \input zapf \input tufte \input zapf \stopcolumnset \stoptext Grüßlis vom Hraban! -- www.fiee.net/texnique/ www.ramm.ch/context/
