XeTeX and GraphicX

Question

When processing with XeLaTeX, some .pdf (I really don't know the difference between them) files give the following error:

! LaTeX Error: Cannot determine size of graphic in xxxx.pdf (no BoundingBox).
! LaTeX Error: Can not include graphics of type: pdf.

I am using graphicx with the [xetex] option, but to no avail. I'm using the following:

XeTeX 3.1415926-2.3-0.9997.5 (TeX Live 2011)
kpathsea version 6.0.1
Compiled with ICU version 4.6 [with modifications for XeTeX]
Compiled with zlib version 1.2.5; using 1.2.5
Compiled with FreeType2 version 2.4.4; using 2.4.4
Using Mac OS X Carbon, Cocoa & QuickTime frameworks

Answer 1

I was getting the same error with texstudio

!LaTeX Error: Cannot determine size of graphic in xxxx.pdf (no BoundingBox).

The error was caused because the "build & view" was set "dvi->pdf chain".

The solution is to set

configuration->build->build & view->compile & view

or "pdf chain".

Answer 2

Ok, it seems the problem is in the includegraphics options I was using:

\includegraphics[type=pdf,ext=.pdf,read=.pdf,scale=0.6]{xxxx}

The following seems to work fine:

\includegraphics[scale=0.6]{xxxx}
