inclusion of jpg error, undefined in ÿØÿà

Question

I want to include a jpg image in a journal paper, and I get the error below when I do LaTeX=>PS=>PDF:

ps2pdf> Error: /undefined in ÿØÿà
ps2pdf> Operand stack:
ps2pdf> Execution stack:
ps2pdf>    %interp_ exit    .runexec2   --nostringval  ...
.
.
.
ps2pdf> MiKTeX GPL Ghostscript 9.19: Unrecoverable error, exit code 1

I can get LaTeX=>PDF but I need the PS file as well. When I remove the jpg image it is compiled without errors and warnings. I know that I can convert my jpg images to eps and get it to work, however, I am obliged by the journal to use jpg images for the biography section. I use TexnicCenter with MikTex. The document class that I am using is IEEEtran and I have the following in it (of course, shortened and modified!), the jpg image comes at the end of the document in the biography section.

Answer 1

The compilation “latex → dvips → ps2pdf” only accepts EPS files.

The code advertised in many examples for the IEEEtran class and that you're using is bad and outdated, but this is another matter.

What you can do is converting your JPEG file into EPS (several programs are available) and keep both versions together. So you will have both whome.jpg and whome.eps and you can compile the file using both methods.

\documentclass{IEEEtran}

\usepackage{graphicx} % don't specify a driver

\ifCLASSINFOpdf
  \DeclareGraphicsExtensions{.pdf,.jpeg,.jpg,.png}
\else
  \DeclareGraphicsExtensions{.eps,.ps}
\fi

\usepackage{amsmath} % don't use the cmex10 option

Notes.

I only left amsmath just to show that the cmex10 option should not be used with it. It's provided only for allowing very old TeX distributions to use the package; you're not using emTeX, are you?

The preference for dvips extensions should be looking first for EPS and then for PS; TIFF inclusion support has long been dropped, so there's no point in adding .tiff.
