new feature / manual

new feature / manual

[Hans Hagen]

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)

bin there, done that (with the file you posted yesterday:

#!/bin/sh
ruby /usr/local/teTeX/share/texmf.local/scripts/context/ruby/ 
texmfstart.rb texexec.pl $@

Is that the right method?

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...

i tried from without thunderbird, which launces firefox, which then hangs (a direct download works); 

concerning the code: interesting mix of scripting an texing-) but beware of redefining externalfigure; there is a hook 

\externalfigurepostprocessors

since conversion normally happens once, the delayed postprocessing is not a real problem; the advantage is that you then have access to all those \applied... variables

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?

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...

Greetings, Peter

this is what the rlx files use

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

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]

It contains only the value of the option= key from
\externalfigure, so it will be empty in this case.

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

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
