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)
