Hi,
There is a new feature + manual, for those who love obscure mechanisms.
http://www.pragma-ade.com/general/manuals/xmanipulate.pdf
Even if you dislike manipulations ... the manual mixes iwona and the new condensed latin modern monospace font.
The preprocess feature is only supported by newtexexec. If you want to automatically run newtexexec instead of texexec, you need to set the environment variable TEXMFSTART_MODE to 'experimental' assuming that you use texmfstart as stub; for those who are not familiar with that:
windows: texexec.bat
@echo off texmfstart texexec.pl %*
unix: texexec (shell script)
#!/bin/sh texmfstart texexec.pl $@
(using texmfstart is a guarantee against changes in the policies of distributions with regards to scripts)
Anyhow, the new feature concerns
- preprocessing of files (e.g. recode for tex files or xslt-ing for xml files) - graphic manipulations (downsampling and beyond)

This doesn't seem to be working here (using OS X + zsh); I always get the "old" texexec.

then you should replace your stub file (something texexec in the bin path)

OK, works like a charm!!

Oh, I just wanted to submit a new module (http://pmrb.free.fr/work/OS/ConTeXt/t-degrade.tex) for down-sampling to the community, so this is no more necessary... Cheers, Peter

anyhow, it does not hurt to have multiple methods

Thank you! I tried to use these macros, but I cannot get \appliedfigureoptions expanded to get the height or width of the figure. The new t-degrade.tex is on the same place. Could you take a look at it please? Cheers, Peter

In fact, the question is just: how to use \appliedfigureoptions and \appliedfigurefilename? In the following test-file, \appliedfigureoptions shows nothing and \appliedfigurefilename gives an error: \starttext \externalfigure[/opt/teTeX/texmf-local/tex/context/sample/spider][width=1cm] \appliedfigureoptions %\appliedfigurefilename %% ERROR: Undefined control sequence. %% \appliedfigurefilename ->@@effilename \stoptext
Nevertheless I send here attached the new t-degrade.tex, in order to let you see how I want to use these two macros.
Another question: when there are two files ./fig.eps and ./degrade/fig.eps how can I tell ConTeXt to prefer loading the second figure when using \externalfigure[fig][options] ? It seems, that \setupexternalfigures[directory={degrade,.}] does not help...

you may try prefix=degrade/
this is what the rlx files use

\expanded{\getparameters[Deg][height=,\appliedfigureoptions]}
else the scanner sees no key=value

I've already tried this, but \appliedfigureoptions seems to be as empty as \relax... Cheers, Peter

Hi Peter,
It looks like this was never answered, and I think the answer is: they are only accessible from within the \externalfigurepostprocessors tokenlist, and are meaningliess/unspecified at the outside.
This works, for me:
\appendtoks \writestatus{figures}{file=\appliedfigurefilename} \to\externalfigurepostprocessors \starttext \externalfigure[/home/taco/maps33/minion/image-test][width=1cm] \stoptext
Does that answer your collector item?
Cheers, Taco

Yes and no, \appliedfigureoptions seems to be empty:
\appendtoks \writestatus{figures}{options=\appliedfigureoptions} \to\externalfigurepostprocessors \starttext \externalfigure[/home/taco/maps33/minion/image-test][width=1cm] \stoptext

Is there any possibility to get "width=1cm" ? Peter

Not using \appliedfigure.... , but if you are willing to mess with \unprotect:
\unprotect \appendtoks \writestatus{figures}{@@efwidth=@@efwidth} \writestatus{figures}{figurewidth=\figurewidth} \to\externalfigurepostprocessors \protect
Not sure if Hans is all that happy with that, though, because the use of low-level @@ef... stuff is precisely what the \applied .. macros were supposed to hide.

hm, @@ef is going to stay, but it is indeed ugly (maybe some day we have \figureparameter
btw, how about:
\usemodule[res-trace]
it will let context write a \jobname.rlg (resource log) with some info

Thanks you, \figurewidth and \figureheight should be enough for me, I think!
Just one last question before improving my t-degrade module: how can I tell ConTeXt to search for images at first in another directory than the current directory? When there are two files ./testimg.eps and ./img/testimg.eps the following test file includes always the first one:
\setupexternalfigures[directory={./img,.}] \starttext \externalfigure[testimg][width=3cm] \stoptext
