Ahoi,
i have some questions about figure libs:
1) i can only access figures from a figure-lib if the
file is in the same directory as the document that
should embed the figures.
For documents in different variants (screen, print)
i would prefer that i can have the figure lib in the
parent directory.
2) is the XML-file that describes the figure-lib really
required to access the figures in the figure-lib:
Suppose the following entry:
<figure>
<file>Figures.1</file>
<label>fig-one</label>
<copyright>Jens-Uwe Morawski</copyright>
<comment>first firgure</comment>
</figure>
that can be accessed with \externalfigure[fig-one]
The page of this figure can be found via:
a) looking for the object that declares the destination
"about: fig-one":
6 0 obj <<
/Type /Annot
/Subtype /Link /Border [0 0 0] /A <</S /GoTo /D (about: fig-one)>>
/Rect [0 0 333.797 108.797]
>> endobj
b) looking for the /Page object that uses this object in /Annots:
8 0 obj <<
/Type /Page
/Contents 9 0 R
/Resources 7 0 R
/MediaBox [0 0 333.797 108.797]
/TrimBox [0.0 0.0 333.79617 108.7967]/CropBox [0.0 0.0 333.79617 108.7967]
/Parent 12 0 R
/Annots [ 6 0 R ]
c) find out at which position this page is declared in the
/Pages dictionary:
12 0 obj <<
/Type /Pages
/Count 5
/Kids [8 0 R 17 0 R 29 0 R 56 0 R 68 0 R]
>> endobj
Maybe this could be done once for all "about:" destinations
for every \usefigurebase[...]. Thus only the figure-lib-pdf
is required.
Btw, while looking in the PDF-file i found:
86 0 obj <<
/Type /Catalog
/Pages 12 0 R
/Names 85 0 R
/OpenAction <</S /GoTo /D (page:2)>>/PageMode /UseNone\relax
/PTEX.Fullbanner (This is pdfTeX, Version 3.14159-1.00b-pretest-20020211)
>> endobj
The \relax after the page-mode looks very TeXish. Is this correct?
Thanks,
Jens

\setupexternalfigures[directory={...,...,...}]

yes, since it determines the page to pick up; of course you can also direct
the page directly using
\externalfigure[somefile.pdf][page=3]
>/Subtype /Link /Border [0 0 0] /A <</S /GoTo /D (about: fig-one)>>
it could be done if pdftex supported access to named pages; parsing the
file using tex macros is not doable (well, partially, but a pain for 500
meg files)
>The \relax after the page-mode looks very TeXish. Is this correct?
no, in spec-fdf, add a space after #6 in:
\xdef\currentPDFviewerprefs
{\ifcase#6 \or\or\or /View...
PS. The fig lib mechanism will be replaced (extended) by a more versatile
resource library system (working on that now)

Hmm, since ConTeXt is so good in finding components and
environments i thought that finding figures should not
that problem. Setting up a specific directory is not
a solution if different authors (with different directory
structure) work on the same document.

I thought that the parsing could be done with TeXUtil (Perl). Is there
no Perl-Module (maybe a wrapper for pdflib by Thomas Merz) that allows
efficient parsing? But, I see that this way still consumes too much
time (for a 500M file). Thus, having the xml-file in place sounds
like the better solution.

Can you give some examples what enhanced functionality is available
then, please.
Many thanks,
Jens

I wonder if it would make sense to have interaction between the figure
library and Taco's forthcoming new bib module. There's obviously
overlap.
Just a thought...
Bruce

hm, actually it's practice here, in order to prevent duplicates, how is
your directory structure for this doc?

next versions of context will also provide you a mechanism for generating
the library

- labeling, language or application dependent
- alternatives, like graphics, placeholders, applets, videos, depending on
the kind of doc instance
- more associated data
- clipping, manipulation, etc
- slide show features

.
|-- Basics.tex
|-- Bib.tex
|-- Fill.tex
|-- Intro.tex
|-- Pre-Cont.tex
|-- Setup.tex
|-- Text.tex
|-- env-bib.tex
|-- env-chart.tex

`-- screen
|-- env-ovl.tex
|-- env-s.tex
|-- piechartmp-s.pdf
|-- piechartmp-s.tex
`-- titel-s.tex
the figure lib is the file piechartmp-figures.pdf||xml in the
"figures" directory. The real documents are the piechartmp-a||s.tex
in their own directories. The .tex-files in the base-directory are
the components and document-wide environments.
As you can see, currently there is a sym-link in the base-dir
piechartmp-figures.xml -> figures/piechartmp-figures.xml
This is because if i use \setupexternalfigures to point to the
"figures" dir, then the piechartmp-figures.xml in the same
dir is not found.
In contrast, if i copy both figure-lib files (pdf and xml)
in the base-dir, then the pdf-file is not found automatically.
Do you have an idea for a better structure? thanks.
Jens
