Sorry another Beamer question

[Taylor, Robert]

Hi all,

Thanks for the help about my previous question which came down to incompatibility issues between beamer and graphics (graphicx) which a one-line fix of code at the start of the document can solve (for anyone with the same problem the line to insert at the start of the latex file is   \makeatletter\let\ifGm@compatii\relax\makeatother
and thanks very much to Paul Thompson for passing this fix along to me)

Emboldened, I thought I'd try out a file with PDF graphs called in it.  Needless to say, it did not go well!  The following call within the latex file

\includegraphics[
natheight=10.6913in, natwidth=14.0472in, height=1.2035in, width=1.5733in]
{C:/Users/rtaylor/Dropbox/tex/graphics/1a__1.pdf}

Led to the following error

....  [17] [18] [19] [20] <use C:/Users/rtaylor/Dropbox/tex/graphics/1a__1.pdf>
! Undefined control sequence.
<argument> ...@base \Gin@ext  image\GPT@AttrShort
                                                  \ifx \GPT@print \ltx@empty...
l.758 \end{frame}
                 %
?

Hit return and it compiles but with the graph simply missing from the output.  The same latex file compiles fine (with the graphs included) on other well-known tex platforms such as scientific word and tex writer, so is this another conflict between beamer and graphics?

Many thanks.

Best wishes, Rob Taylor

Sorry, the problem yesterday was a conflict between geometry and beamer, not graphics and beamer ... so probably unrelated to today's problem ....

I think I solved this myself amazingly enough (!), by finding this on the web:

"With natwidth and natheight you are trying to specify a bounding box which is not supported by the pdftex driver:
the driver pdftex.def does not support the manual specification of the bounding box, because it is not needed. If the user wants to have a portion of the image, there are options viewport and trim to specify this wish in a cleaner way. Option bb is treated as viewport with a warning."

In case this helps anyone else.

Cheers, Rob

Now, there you go. You have figgered out how to hack. That's the issue - it's not how to do things when they work correctly (The LaTeX Companion covers much of this, but does not include my class in its coverage), but how to solve problems.

Please send a full example: beamer works fine in general with graphicx
(as you'd expect, I guess, for a class for making visual presentation
material!).

Sorry but this is a hack and not a solution. If you want to use it
fine, but you shouldn't spread it around. So correct way to solve
the problem is to make a minimal example and to show its log-file so
that one can analyze what is wrong with your system.

While viewport is the correct option, natwidth/natheight imho
shouldn't give an error but like bb issue only a warning.

I reported the problem to the LaTeX team and I think David will add
some code to avoid the error soon.

That was from 2010. And the context was:

=========================
Update beamer. Or put

\makeatletter\let\ifGm@compatii\relax\makeatother

before \documentclass.
=========================

So it should be clear that with a current beamer it should no longer
be necessary. Such measures are sometimes needed for a short time
until some update has reached the user. But after 6 years you should
move them to the bin.

Actually you should never rely on such old code without have checked
quite carefully if the context for which the code was written is
still valid.

That hack works unlike the files downloaded by the basic miktex installer which I also updated as you are meant to .... That suggests the hack is still needed for exactly the reason it was needed before.

Well as the code you are using is from me you should expect that I
know what it is about and that I have every right to claim that it
is not a good idea to use it today.

I do have a miktex updated today and this here works fine:

\documentclass{beamer}
\usetheme{CambridgeUS}

\begin{document}
\begin{frame}{abc}
blub
\end{frame}
\end{document}

As I already wrote: what you are doing in your own code is up to
you. But when you start to spread around wrong code and claim this
code is a solution you are misleading other people and I think this
is unfair to them.

There are a number of situations in which we need to fix our code:

1) I am preparing a presentation for Oct 31. There is a problem. I submit a bug report. It takes 10 days to fix the problem. I finish and present my report.

All is good. You have time. No hacks are needed.

2) I am preparing a presentation for Oct 31. There is a problem. I submit a bug report. It takes 10 days to fix the problem. I finish and present my report.

You don't have time to wait. You look for a hack, and hope to finish. In addition, how are you to look at interim results?

3) am preparing a presentation for Sept 22. There is a problem. The presentation worked until the last update of bemer.
 
You don't have time to wait. You look for a hack, and hope to finish.

>From your perspective, Ulrike, I think that you should ENCOURAGE hacks, not discourage them. LaTeX, under MikTeX, whatever, is an open-source tool. People should be able to fix minor issues. Like earlier today someone noted a file was missing. I googled, found the file, could have placed it correctly and gone on.

Don't dump on people for being resourceful. It's good to have permanent fixes. It's also good and important for things to work in the moment, until the permanent fix is made.

Please check the logfile exactly which files are being read. Maybe
latex reads some outdated version of a file which does not come from
the current MiKTeX.

Thanks for that reminder. This is again an important tip that inexperienced users do not know about. They think that MikTeX knows which file to pick.

 Of course, it usually does. But that can be bunged up in a number of ways, and looking for duplicate files is a key step in some difficult cases. I know that I have that problem, in that I tend to stash outdated versions of stuff on the local tree.

Then you haven't seen much of me ;-)

I sometimes have quite clear views and try to get them around.

And in this case I think it is very important not to confuse
work-arounds and hacks with real solutions.

I don't have any problems with peoples with some time pressure using
a hack -- I'm doing is sometimes too. But it is dangerous to think
of such a work-around as a solution as it means that you won't
tackle the real problem. The problem my code from 2010 tried to
solve should be gone long ago and if Robert (or someone else) still
have it something is wrong with their texsystem.

Robert sent me the log-file offline and what you (and me too -- I
know why I asked for the log-file ...) suspected is true:

He has some files from an outdated beamer version from 2007 in the
document folder.
