[pdftex] graphic{s,x} PNG + pdflatex bug

[Nico Schlömer]

Hi all,

I experienced a weird bug using \includegraphics of the graphicx
package with pdflatex 1.40.10.

I try to load the attached PNG file, and unlike with other PNG files,
pdflatex would just bail out with

==================== *snip* ====================
[...]
[Loading MPS to PDF converter (version 2006.09.02).]
)
! Dimension too large.
<argument> \wd \@tempboxa
l.7 \includegraphics{img1.png}
?
==================== *snap* ====================

David Carlisle, maintainer of graphicx, suggests that may be a bug in
pdflatex -- What do you reckon?

Cheers,
Nico

the error message is a bit odd, but "classic" tex  wouldn't be able to
read a png file to determine its size so you should have an error
about an unknown size. is this pdftex (and if so what version?)
perhaps it is passing some odd data back to the macro layer.

you may be best to ask on the pdftex list pdftex at tug.org where the
current maintainers of pdftex and the latex support files for pdf
(pdftex.def) can be found.
