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

Setting up a specific directory is not a solution if different authors (with different directory structure) work on the same document. > >2) is the XML-file that describes the figure-lib really > > required to access the figures in the figure-lib: > > 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) 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. > PS.

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.

There's obviously overlap. Just a thought...
