Figure referencing problems

Figure referencing problems

[Wolfgang Miurth]

Hi,

I have troubles with referencing images. 

At first \in does not show a figure number but \at shows the correct page of the figure.

In the archives I found a post from Wolfgang Schuster [1] with a sample that worked for him. I tried this, but there 
is no figure number visible in my document.

%==========================
\starttext

\startuseMPgraphic{circle}
draw fullcircle scaled 1cm;
\stopuseMPgraphic

\placefigure
  []
  [fig:ref]
  {Text}
  {\useMPgraphic{circle}}

\in{figure}[fig:ref]

\stoptext
%==========================

How can I fix that?

Further \about{figure}[fig:ref] brings an error "Use of \about doesn't match its definition.". I used the syntax from the manual
on page 205. How can I use the caption of a figure in an reference?

My last question is how I can remove the color of links to references in a document.

I am using MkIV 2009.08.30 12:25.

Thanks for your help

Wolfgang Murth

This works fine for me with

ConTeXt  ver: 2009.10.02 13:14 MKIV  fmt: 2009.10.4  int: english/english

and also with

ConTeXt  ver: 2009.09.28 09:02 MKIV  fmt: 2009.10.3  int: english/english

So you probably need to upgrade.

\about works with the above versions. The usage is \about[fig:ref] 
(without the curly brackets)

\setupinteraction[color=]

Hi,

Thanks for your help. Two of three problems are solved.

>So you probably need to upgrade.
Yes. That was solved the problem. 

>\about works with the above versions. The usage is \about[fig:ref] (without the curly brackets)
Yes, also this works. I used the syntax from the cont-eni.pdf on page 205
   \about{...}[ref]

>\setupinteraction[color=]
That does not work in the latest version. The style parameter is recognized, but ot the color parameter.
Following produces red links, even if green is selected.

%=========================
\setupinteraction
[state=start,
color=green,
style=]
\starttext

\startuseMPgraphic{circle}
draw fullcircle scaled 1cm;
\stopuseMPgraphic

\placefigure
  []
  [fig:ref]
  {Text}
  {\useMPgraphic{circle}}

\in{figure}[fig:ref]

\at{figure}[fig:ref]

\stoptext

%=========================

Best wishes 

Wolfgang Murth

This is a bug in mkiv. It works correctly in mkii.

Hi Wolfgang,

I've been fiddling with this a bit as well, and found that the color parameter
is only used for links to other pages. Links to the same page use the
contrastcolor parameter. I'm not completely sure that this is the actual
criterum, but at least contrastcolor is involved as well.

The following makes all links black again for me:

  \setupinteraction[state=start,color=,contrastcolor=]

Thank you. That was the trick.

For completeness, I've documented the setupinteraction command a bit better at
http://wiki.contextgarden.net/Interaction as well.

you also need to set the

contrastcolor=green % color of link on same page

since it's independent
