[Tex/LaTex] How to set an Inline figure matching the text height

Question

I want to put a very small figure inline with text. The figure must have the same height as the line it is positioned in. I have this:

Some text... \includegraphics[height=\baselineskip]{picture.png} ... some more text. 

This, however, makes the figure slightly too large, filling the whole space up to the bottom of the line above. I want the figure to be only as high as the capital letters of my font. What's the right way to do this?

Answer 1

Tell TeX that the figure should be as high as a “B”:

Some text... 
\includegraphics[height=\fontcharht\font`\B]{picture.png} 
... some more text. 

You probably want to define a special command for this:

\newcommand{\mychar}{%
  \begingroup\normalfont
  \includegraphics[height=\fontcharht\font`\B]{picture.png}%
  \endgroup
}

and type your paragraph as

some text \mychar{} some text

If you plan to use this also in titles or captions, it's better to say

\DeclareRobustCommand{\mychar}{%
  \begingroup\normalfont
  \includegraphics[height=\fontcharht\font`\B]{picture.png}%
  \endgroup
}
