hm, i wonder, since it's a bunch of conflicting specs; also, openaction
has not been around from the start of pdf (and got more robust later),
and access to the page object number in pdftex is pretty recent
Hello Hans,
thanks for all your explanations!
Perhaps LaTeX does not use openaction. I've made a test with
pdflatex-0.13d and pdflatex-1.30.4 with the following input:
\documentclass{article}
\pdfcompresslevel=0
\usepackage[pdfstartview=FitBH,pdfpagemode=FullScreen]{hyperref}
\begin{document}
\tableofcontents
\newpage
\section{bla}
\end{document}
The two results are in http://pmrb.free.fr/tmp/pdfstartview/
acroread-4.0.5 and acroread-7.0.1 open these files without problems.
The result of a grep -a FitBH test-0.13d.pdf test-1.30.4.pdf:
test-0.13d.pdf: /S /GoTo /D [9 0 R /FitBH ]
test-1.30.4.pdf: /S /GoTo /D [10 0 R /FitBH ]
If you could provide a command like
\doittheLaTeXway[pdfstartview=FitBH,pdfpagemode=FullScreen]
that would be really nice!

Hello Hans,
thank you for the upload! I've made a test with the following input:

It works quite well. But when changing the zoom-level and then clicking the
reference, the zoomlevel goes back to minwidth. But this is only a minor
issu...

I assume that is because the /FitBH should match what is implied by
the focus=minwidth, I just freewheeled a bit. The /D(estination) in
this is the top-level page object for page 1, so it actually does an
implied \goto{}[firstpage].
I don't know how to get the object number (I simply reverse-
engineered the hyperref output). It is not all that sneaky an
approach. I don't think it will work on pre 5.0 acroread, though.

approach. I don't think it will work on pre 5.0 acroread, though.
over time, the possibilities of pdf has improved as well as changed:
- first there were only page destinations
- then came names ones
- cross doc links were implemented differently
- then there was a behavioural change in optimizers/viewers
- views are not supported in certain named destinations
- etc
this all resulted in context supporting a mixture of destinations (page
and named) and either or not providing support for views, depending on
what method was chosen.
the solution that taco suggests is possible now that in pdftex we have
pdfpageref (ok, a bit of a lie: context could sorty out page object ref
numbers itself but i never used that here due to mem limitations which
now are gone)
however, one needs to keep in mind that if we support things like this
we also assume recent viewers (ok now, but some time ago both linux and
apple were behind with viewers)
i'll adapt the pdf driver a bit so that we can do what you want, under
the assumption that everyone runs the latest pdftex (i normally take a
one year period before i assume that) as well as that one has a version
5+ viewer.
\setupinteraction[state=start,focus=width,openaction=firstpage,page=yes]
\starttext
the page actions (like firstpage) will use the obj ref approach now instead of
the auto page destinations, and with page=yes one forces
all destinations to be page destinations (which is needed on order to
get the view working; keep in mind that one then looses cross document named
referencing, only cross doc page referencing remains (no real problem, unless
one refers from outside a pdf)
\stoptext
i'll upload a current with a slightly adapted driver (extra option which is now
default; taco: just run a diff on spec-fdf.tex and you'll see what happens)
\setupinteraction[state=start,focus=width,openaction=page(3),page=yes]
\starttext
test \page
test \page
test \page
test \page
test \page
\stoptext
works ok too

The same is true for more features. Only with acrobat 5 pdf became a bit more stable also keep in mind that context has chained annotation support as well as some other features that make it tricky to use certain tricks; in the deiver files you will find some workarounds, like adding quotes around destinations on order to make sure that acrobat 3 does not ignore them - it simply assumed some funny first char sort order in named destination, probably some optimization; or special treatment or spaces or ... other tricky areas are for instance widgets: context has always built the datastructures needed, and i'm sure not every tex package does that, thereby just depending on the recovery capabilities of acrobat (it indeed reconstructs fields arrays at startup) but context could not depend on that because it supports clones and copies of fields right from the start similar weirdness happens (happened) with javascripts: the spec supported a list of scripts, while viewers didn't; and then we don't even talk about initialization ... so, again, it's no problem to get something working for a certain version, but i always want to make sure that we are as backward compatible as possible or take special resources (related to plugins) keeps changing, never works 100% in the first release of a reader, so i more or less decided that, apart from some playing around, its best to wait till N.0.2 or higher -) Hans - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl - ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context

openaction is there for a while, the trick is (at least that is

like a hack;
(the best way to find solution is to see what acrobat itself does and
then look into the saved file -)
so, i can imagine latex to do an open action like that
however, in context openactions can be more complex, like:
openaction={page(10),FitWidth,startmovie(whatever)}
so, if one really wants a fith -infty than we need to make a special def
for that (but we have FitWidth)

I was merely looking for a way to open the document on 100% (on a
wide/high resolution screen there's usually no need for FitWidth
since you only see one third of a page, twice as big as the usual size
for comfortable reading).
I didn't write yet since it's not on the priority list and it doesn't
have any influence on quality, but it's very handy, esp. on Windows
when you have to open the document each time you compile it and
consequently scale it properly again and again.
Scaling on a certain percentage takes some more effort that a usual
FitWidth, but should be doable.
Thanks,

Hello Hans,
focus=... does *not* set the right zoom-level at startup of acroread
and it *changes* the zoom-level when clicking on a reference.
So, my suggestion for our needs is startfocus=
one of the problems is (and this has changed in viewer over time, which is why
i never bothered too much about it) is that the opening options are controlled
differently from the annotation views
links:
\setupinteraction[state=start,focus=width]
opening:
\setupinteraction[state=start,focus=width,openaction=FitWidth]
or
% \setupinteractionscreen[option=max] % bookmark fit doublesided
or (fails):
% \setupinteraction[state=start,focus=width,openaction=page(1)]
FitWidth and FullScreen don't go well together (kind of contradict);
The open action can be chained as can other goto's:
openaction={page(2),FitWidth}]
it is possible to use FitH trickery with infinity offsets but it's not only
ugly but i also consider it subjected to changes in future viewer versions; in
the past i've done numerous tests with such features but nowdays i tend to be a
bit less eager to implement potentially messy features
FitWidth is mapped onto a named action which is rather robust
