I seem to be getting a strange error after updating MiKTeX 2.9. I am using pdfLaTeX and TeXmaker with the graphicx package to include .png images. When I try to compile, I get the error LaTeX Error: File 'title' not found. If I include the file extension, then the error becomes LaTeX Error: Cannot determine size of graphic in title.png (no BoundingBox). I wasn't getting these errors a few days ago when I started creating my presentation. It has also worked without problems in the past.

MWE:

\documentclass{beamer}
\usepackage{graphicx}
\graphicspath{{figures/}}
\begin{document}
    \title{title}
    \author{author}
    \date{date}
    \titlegraphic{\includegraphics[scale=0.5]{title}}
    \frame{\titlepage}
\end{document}

Also, from the logfile it seems that pdfLaTeX is not in PDF mode, and that all graphics are being treated as .eps: 

Package: ifpdf 2011/01/30 v2.3 Provides the ifpdf switch (HO)
Package ifpdf Info: pdfTeX in PDF mode is not detected.
...
File: title.png Graphic file (type eps)

Does anyone know how to fix this problem?

    Welcome to TeX.sx! The first problem is related to the second (and actual) problem. latex cannot determine the natural dimensions of an image. So the real question is: Why is pdfLaTeX not in PDF mode? Does your MWE compile if you use pdflatex from the command line (pdflatex <filename>)? It seems as if your editor is set up to use latex rather than pdflatex. – Qrrbrbirlbel Feb 18 '13 at 05:17
  • @Qrrbrbirlbel I get the same error messages when using pdflatex from the command line. I checked the options in Texmaker, but it does look like it is set up to use pdflatex. The first line of the logfile also shows This is pdfTeX, Version 3.1415926-2.4-1.40.13 (MiKTeX 2.9) (preloaded format=pdflatex 2013.2.18) 18 FEB 2013 16:52 – Ian Gralinski Feb 18 '13 at 05:55
  • That usually means that TeX isn't able to process the image, either because the image's format isn't supported or just the image isn't found. – vonbrand Feb 18 '13 at 06:17

    Could it be that you have several files with basename title, that some of them have a pdf or an eps extension and that they're corrupt? If yes, a possible solution may be adding the extension to the filename title. –  Feb 18 '13 at 06:23
  • @vonbrand I was able to get my presentation to compile with images included a few days ago, so perhaps it's something to do with updating MiKTeX. I will try on a different computer at home without updating to see if the problem persists. – Ian Gralinski Feb 18 '13 at 06:52
  • @MarcvanDongen, you could be right. Or some wrong setup for imageformats. Try leaving only the "right" format images around. Clean the temporary files, and re-run LaTeX. – vonbrand Feb 18 '13 at 06:55
  • @MarcvanDongen @vonbrand In my figures subdirectory I have a total of 7 png images (no other formats). I can open the images to view so they don't appear to be corrupt. I also tried removing all files except the tex source and images, but the error persists. – Ian Gralinski Feb 18 '13 at 07:00

    @m0nk3y: There was an update some days ago (12.2.) which broke the formats. The error has been corrected but perhaps you still have remains. Run the update manager (admin + user mode). Recreate all formats. If the problem persist you will have to find the local ini-files and correct them manually. If you are in a hurry: you can also put \pdfoutput=1 at the start of your document, this will switch the mode back to pdf. – Ulrike Fischer Feb 18 '13 at 08:22
  • @UlrikeFischer I have the same problem with the PNGs despite updating to the current version. Thanks for the \pdfoutput=1 trick, though. It works well for the time being! –  Feb 18 '13 at 13:22

    @hjschulz: Updating is not enough. You should also recreate the formats (as user). If this doesn't help: Rename in the UserData and (perhaps) CommonData-root (not in the main root!) in the folder miktex/config formats.ini, language.ini and if it exists pdflatex.ini. And then recreate the formats again. (This can change the language and format settings, you can reset them in miktex->settings). – Ulrike Fischer Feb 18 '13 at 14:30
  • I tried compiling my document at home and it worked, both before and after updating MiKTeX. So it looks like something has gone wrong with this installation as @UlrikeFischer suggested. I also tried adding \pdfoutput=1 after \documentclass{beamer}, but the error persists. @UlrikeFischer- I tried renaming formats.ini, languages.ini and pdflatex.ini in the installation directory and then updating formats, but I just received error messages so I changed the filenames back to the originals. Is there anything else I can try apart from reinstalling MiKTeX? – Ian Gralinski Feb 19 '13 at 06:41

    @m0nk3y: I explicitly wrote that you should not change files in the main root (=installation root). Go to miktex-setting, tab "root", activate "show miktex roots", it will show you the path to UserConfig (not UserData as I wrote by mistake in the previous comment). There you will find the local ini's. – Ulrike Fischer Feb 19 '13 at 08:35
  • @UlrikeFischer: I opened MiKTeX settings as user and checked "show MiKTeX roots". I then looked in the locations specified as "UserConfig", "UserData" and "CommonConfig", but none of those locations (in miktex/config) contained the ini files. So I tried going to CommonConfig/miktex/data/le/pdftex, renamed pdflatex.fmt and pdftex.fmt, and then recreated formats. This then allowed me to compile without errors. If you post an answer, I will accept it. Thanks for your help and patience. – Ian Gralinski Feb 21 '13 at 00:29

This problem was solved by renaming pdflatex.fmt and pdftex.fmt in the CommonConfig/miktex/data/le/pdftex directory and then recreating formats as "user".
