Error including image in Latex [closed]

I am getting the following error while compiling my Latex File :

! LaTeX Error: Cannot determine size of graphic in tree.jpg (no BoundingBox).

Why do I get this error ? What has this to do with an .eps file ?

In fact, I could compile it fine with MacTex on my machine. But when I submit it online to a scientific journal for publication, it compiles it on the server and sends me the resultant PDF which has all these errors that prevent it from compiling.

I am using the following syntax for including the images :

\begin{figure}[!h]
    \begin{center}
        \scalebox{0.45}{
            \includegraphics{tree.jpg}}
    \end{center}
            \caption{\small A sample}
            \label{tree}
\end{figure}

What should I do ? Could it be that their server is using an old compiler ?

UPDATE : It finally worked. I converted the first image to PDF and the compilation happened perfectly. I guess it used the bounding box value from that PDF and applied it to all images.

Are you using pdflatex? Cause latex only supports vector graphics (read: eps) – Maiga 8/4, 2009 at 21:36

I don't know the engine they are using on the server. My machine has MacTex and it is able to compile it. – Remonstrant 8/4, 2009 at 21:40

Ah, yes. s/you/they/. Perhaps you should contact the journal and ask them about the specifics of their latex implementation. – Maiga 8/4, 2009 at 21:43

For what it's worth, JPG is quite possibly the worst image format to use when you're going to print something (because of the quality degradation). In Latex EPS is best, PDF is a close second. – Overstudy 8/4, 2009 at 21:46

@David: EPS and PDF are essentially equivalent when it comes to image quality. It just depends whether you're using LaTeX or pdfLaTeX as to which you'd choose. – Phonoscope 9/4, 2009 at 2:14

Should we migrate this (and other tex questions) to tex.stackexchange.com? – Disciplinant 6/1, 2011 at 13:54

@euphoria83: I flagged the post for moderator attention. Perhaps you can do that too? If we don't hear anything I'll post something on meta about migrating the questions from this tag. – Disciplinant 6/1, 2011 at 15:21

I've had the same problems including jpegs in LaTeX. The engine isn't really built to gather all the necessary size and scale information from JPGs. It is often better to take the JPEG and convert it into a PDF (on a mac) or EPS (on a PC). GraphicsConvertor on a mac will do that for you easily. Whereas a PDF includes DPI and size, a JPEG has only a size in terms of pixels.

( I know this is not the answer you wanted, but it's probably better to give them EPS/PDF that they can use than to worry about what happens when they try to scale your JPG).

Thanks. Great help. But then why is it working on my machine ? How is it getting the bounding box values ? – Remonstrant 8/4, 2009 at 21:38

MacTex seems to be more robust than other Tex distributions that I've seen. After working with too many academic publishers I've realized that I can never find something as old and incompatible as whatever they're using, so I just create EPS or PDFs. – Tomboy 8/4, 2009 at 21:41

By the way, if you draw diagrams take a look at OmniGraffle. One of the best reasons to use a Mac – Tomboy 8/4, 2009 at 21:44

Yeah, its surprising how the interface for CS journals are so out-dated. How do I convert to PDF format ? Is GraphicsConvertor a software provided with the OS ? I could not find it here and on the internet. – Remonstrant 8/4, 2009 at 21:56

@euphoria: Which journal are you publishing to? A lot of the ACM journals and conferences actually take word files, which is even worse. – Tomboy 8/4, 2009 at 22:1

Even this journal takes word. I guess that why they don't care much about having an up-to-date latex engine on the server. But still, what's GraphicsConvertor? Is that a software ? – Remonstrant 8/4, 2009 at 22:3

Yea, it's a really good conversion software for the mac. Costs a lot, but you could use the demo for a while. lemkesoft.com I use it for all my screenshot and conversion needs. – Tomboy 8/4, 2009 at 22:5

Enjoy. Congratulations on the paper ! I've only done conferences so far. – Tomboy 8/4, 2009 at 22:43

you work on really cool stuff. API documentation is always a big pain. I applied to CMU too. But Luis Von Ahn couldn't help me get in. I had worked on CAPTCHA before. – Remonstrant 8/4, 2009 at 23:0

@euphoria83: I think Luis has got his hands full with so many students and people working for him. And this year CMU's been feeling the crunch so the number of students it can support has been lower. – Tomboy 8/4, 2009 at 23:9

IT was a fun topic (took me a while to get to it), it's a pity I'll never follow up on it ever again as I'm going to the industry. I hope I can at least get people to use my eMoose tool. – Tomboy 8/4, 2009 at 23:10

To include png and jpg, you need to specify the Bounding Box explicitly.

\includegraphics[bb=0 0 1280 960]{images/some_image.png}

Where 1280 and 960 are respectively width and height.

that would make the document terribly fragile to included image size changes, wouldn't it ? – Sideward 14/3, 2013 at 10:13

@sylvainulg : you are right – Clothbound 14/3, 2013 at 23:59
