Cropping an image for use in a tikzpicture

Question

How should I crop an image to use in a tikzpicture?

I declare an image in my header

\pgfdeclareimage{myimage}{image.png}

Then I want to use a cropped version of myimage in a tikzpicture

\begin{tikzpicture}
    [...things being drawn...]
    \pgfuseimage{image}
\end{tikzpicture}

Is there an option akin to \includegraphics[trim={0 1cm 0 0}]{image}?

Answer 1

An \includegraphics command can be used in node's contents part, therefore if \includegraphics[trim={0 1cm 0 0}]{image} is the desired solution, just insert it into a node:

\node[inner sep=0pt]{\includegraphics[trim={0 1cm 0 0}]{image}};

inner sep=0pt is included to avoid any empty space between the image and node's border.
