Hi,

I'd like to make the CD-ROM catalogue (PDF) of an architectural exhibition in ConTeXt.

In short the general idea is:

- First you have a page with a map showing the locations of the different buildings. - Then you should point on location you are interested in and jump to the page where this particular building is described in detail. - Then again you should be able to jump back to the point (centered?) on the map where you have started.

My main question now is:

Is it possible in ConTeXt to locate/define on the map (one image) certain points/areas that will contain the links to respective the detail page?

Ha, when i tried to locate that old code, i ran into a bug (\dosingleempty is less tolerant than 5 years ago), so first a patch:

\unprotect

\def\dodostartfigure[#1][#2][#3]#4\stopfigure {\doifelse\v!test\@@exoptie {\teststartfigure[#1][#2][#3]#4\teststopfigure \let\@@exhokjes\v!aan} {\let\@@exhokjes\v!uit}% \setvalue{\??ef\??ef#1}% {\def\next{\placestartfigure[#1][#2][#3]#4\placestopfigure}% \dosingleempty\next}% \doifundefined{#1}{\setvalue{#1}{\getexternalfigure{#1}}}}

\protect

Now you can do things like:

\setupinteraction [state=start]

% \setupexternalfigures % [option=test]

\startfigure[TheProces][work016a][factor=200] \referring (10.7,9.4) (4.3,2.3) [r:psfile] \referring (16.5,16.5) (4.3,2.3) [r:pdffile] \marking (10.7,9.4) (4.3,2.3) [m:psfile] \marking (16.5,16.5) (4.3,2.3) [m:pdffile] \stopfigure

\starttext

\title{Files}

\placefigure {Whatever files we use.} {\TheProces}

\title[r:psfile]{PostScrip Files}

We're talking about PostScript files, see \in[m:psfile]!

\title[r:pdffile]{PDF Files}

We're talking about PDF files, see \in[m:pdffile]!

\stoptext

Uncommenting the test will provide you a suitable test bed.

(Sorry for the bit oldfashioned code; it originates from the pre pdf time)
