[Tex/LaTex] insert a vertically centered image in math mode

graphicsmath-modevertical alignment

In Mikael Öhman's answer to this question, he provides some code for placing an image in math mode as a symbol using the \mathord declaration. I can define a new command in the preamble using this, and it works, but the image is placed on the baseline of the equation.

I want it to be a good deal taller than typical text, so ideally I could use \vcenter to center it vertically. When I do include the centering, the image is treated as if it were as wide as the page, i.e. there are about 6 inches of white space following it. (The image is closely cropped, so the white space is certainly created by LaTeX.

Where is the glitch in my code?

\newcommand{\bone}{\mathord{\includegraphics[scale=0.5]{../images/dog_bone.pdf}}}

Use \hbox within \vcenter:

\vcenter{\hbox{\includegraphics{filename}}}

You could add \vcenter{\hbox{...}} to your macro definition if you always use it vertically centered.

Btw. generally you could simply use additional braces instead of \mathord to get the normal spacing.

It won't scale nicely with font size, but a simple approach is straightforward. The image should have a tight bounding box, which you can achieve with tools like pdfcrop.

\newcommand{\mysymbol}{\mathord{\includegraphics[height=1.6ex]{symbol}}}

\mathord is suitable for ordinary symbols, since you indicated that it would be used similarly as \alpha.

With the suggestions from the comments, I wrote a better solution.

\newcommand{\myfancysymbol}{
 {\mathchoice
  {\includegraphics[height=1.6ex]{symbol}}
  {\includegraphics[height=1.6ex]{symbol}}
  {\includegraphics[height=1.2ex]{symbol}}
  {\includegraphics[height=0.9ex]{symbol}}
 }
}

The symbol scales like a capital X for subscript and subsubscripts.

[Tex/LaTex] Shifting a symbol vertically in Math mode

You can redefine \sqsubset to take an optional argument that would raise it:

enter image description here

\documentclass{article}
\usepackage{amsfonts}% http://ctan.org/pkg/amsfonts
\let\oldsqsubset\sqsubset
\renewcommand{\sqsubset}[1][0pt]{%
  \mathrel{\raisebox{#1}{$\oldsqsubset$}}%
}
\begin{document}
$S\sqsubset\mathbf{P} \quad S\sqsubset[5pt]\mathbf{P} \quad S\sqsubset[1pt]\mathbf{P}$
\end{document}

The updated \sqsubset is set as a binary relation \mathrel. Note that if you want to use square brackets after \sqsubset, you need to surround it with braces. The new usage is \sqsubset[<len>] where <len> is any recognized (La)TeX length.
