General ⇒ latexdiff - how ignore \newcommand regions?

[BinaryBen]

Hey all,
I've been tinkering with 'latexdiff' - I have it working, but I'm comparing two large files with lots of subfiles in folders, but need to exclude specific regions, as it prevents latex generation:

Are there any simple examples of how to ignore a `newcommand' I specify in a macro? For example, I have the macro '\myfigure' with four args {}{}{}{} - is there any way of making it ignore new and old changes that included this command and its args?

\newcommand{\myfigure}[4]{
\begin{figure*} % [h] % [htbp]
\centering
\includegraphics[width=#4\textwidth]{#1}
\caption[#2]{\textbf{#2} - #3}
\label{fig:#1}
\end{figure*}
}

Thanx,

Ben
