How to get the figure size

How to get the figure size

[Gilbert van den Dobbelsteen]

Hi there,

This is probably very trivial but I need to do something like this:

  \presetexternalfigure[foo][somefig][height=100pt]
  \framed[width={\figurewidth[foo]}]{Some contents}

Are there any macro's like this? I need to have the height too.
I need it because I have a lot of figures with the same height, but with
different widths.

O yeah, and another problem: I use ActivateState perl, and some DJGPP perl
(you know, a port that runs under DOS/WIN/OS/2 *and* win95 and it has long
filename support)
and there are some differences:

- The DJGPP port is much faster (and I mean a lot faster here)

- The DJGPP port does globbbing correct, e.g.:
    texutil --figures --epspage *.eps
  works fine, while the ActiveState port doesn't (texutil says it doesn't
know any figures *.eps).

Perhaps I did something completely wrong (Ok, Wybo, I'll switch to Linux
some day). I have to stick to the ActiveState port because I use perl/Tk and
ODBC database connectivity, which doesn't run under the DJGPP port.

Likely cause: the DJGPP port is compiled with "gcc -03". Speed
optimizations on Windows compilers are usually off because the result
code is too buggy to be usable.  Also, the DJGPP port uses dpmi
memory. Silly, but that is sometimes faster dan "real" windows memory
(no page swapping inside the allocated block).  On the down side: the
rest of your machine will swap much harder. And another: no dll
code. loading dll's is *slow*. And yet another: Windows almost only
calls the scheduler/task switcher on Win32 syscalls, which of course
DJGPP almost never executes...

Install bash ;-) The problem is command.com, not perl. It so happens
that DJGPP has a built-in fix and the windows don't. Hans, I thought
we had fixed that with use File::DosGlob etc?

Definately helps.

Add: 

use File::DosGlob ; 

Change: 

sub CheckInputFiles
 { @UserSuppliedFiles = glob @_[0] }

But, does this work ok under Unix? Can you check that? Or should I test
for dos/unix? How etc. I looked into it some time ago but got verrrrrry
frustrated.

I'm not sure what you need it for, but the most general way of doing
this kind of things is using tex's box mechanism. Anyhow, this is one
way of doing things: 

(1) Put this somewhere, e.g. on cont-new.tex (I added it to core-fig, so
in th enext release it's there). 

\unprotect

\let\figureheight=\!!zeropoint
\let\figurewidth =\!!zeropoint

\def\getfiguredimensions%
  {\dodoubleempty\dogetfiguredimensions}

\def\dogetfiguredimensions[#1][#2]%
  {{\setbox0=\hbox{\externalfigure[#1][#2,\c!object=\v!nee]}}}

\protect

(2) Now you can ask for the dimensions

\getfiguredimensions[koe.pdf]

width: \figurewidth, height: \figureheight

(3) But, when you just placed the figure, you don't need to ask for it,
because the dimensions are already available in \figurewidth/height (so
you sort of guessed right about this low level secret macro).

The same for tex -).

Ha, I just installed active perl and never tested that -)

That's why I switched also: Tk (currently I run the perl/tk texedit
version, with tex and metapost support etc).

It will work OK for all files that do not have * or ? in their name...

I don't have any, do you? :-)

Nope, only MsWord users have those: "How are you?.doc" ;-)

Actually, I tried this with Word 97 SR-2, and this filename did not save,
i.e. it stayed in the Save As dialog box.

When I tried to rename a file within Word or Explorer I got:

	A filename cannot contain any of the following characters:
	\/:*?"<>|

We're seeing progress here!

Groetjes,

Berend.

Not really. It's been like this since the first incarnation of msdos.
A few changes have occurred though: long file names containing multiple
dots and spaces are now legal (but a bad idea in a TeX environment).

They have been legal in Unix systems for long. But it is still difficult to
work with such filenames though :-)

Change routine CheckInputFiles in texutil.pl to:

sub CheckInputFiles
  { my ($UserSuppliedPath) = @_ ;
    @UserSuppliedFiles = glob $UserSuppliedPath }

This is the correct implementation IMHO. Hopefully in IHHO (In Hans Honest
Opinion) soon as well :-)

Yes, but it went wrong somewhere else (forgotten where). But, if IYHO
you can garantee correct running under unix as well, It will be a
permanent change. Looks like the file::dosglob is not needed.

This is the only thing that works under Unix. I copied it straight from my
Unix system.
