% Standard text for constructor:
\newcommand{\constructorblurb}[1]{
\begin{Constructor}
An object instance of \class{#1} can be created with the
constructor \methoduse{new()}\index{Methods!new()}:
\begin{SmallExample}
\$obj = #1\deref new();\\
\$obj = #1\deref new(\parameter{width}, \parameter{height});
\end{SmallExample}

If \methoduse{new()} is called without arguments, the constructor will
return an image of size 300\ensuremath{\times}400 pixels. If
\methoduse{new()} is called with two arguments, \parameter{width} and
\parameter{height}, it will return a \class{#1} object of the
desired size.
\end{Constructor}
