How can I indicate the bounding box using .bb files in \includegraphics?

Question

Is it possible to use a .bb file (generated with, for instance, the "ebb" program included in MiKTeX) to define the bounding box of .png files when using \includegraphics?

I can define the bounding box in the optional argument to \includegraphics directly, like \includegraphics[bb=0 0 100 100]{file.png}, but I'd like to be able to define this outside of the code, using the generated .bb file. Is this possible?

Answer 1

I figured it out. Applying

\DeclareGraphicsExtensions{.png, .bb}
\DeclareGraphicsRule{.png}{eps}{.bb}{}

before including graphics using \includegraphics{file} (without the extension) solved it. :)

Just in case someone have the same problem.
