\constfunc{unsigned long}{ComputeHistogram}{\param{wxImageHistogram\& }{histogram}}
Computes the histogram of the image. {\it histogram} is a reference to
wxImageHistogram object. wxImageHistogram is a specialization of
\helpref{wxHashMap}{wxhashmap} "template" and is defined as follows:
\begin{verbatim}
class WXDLLEXPORT wxImageHistogramEntry
{
public:
wxImageHistogramEntry() : index(0), value(0) {}
unsigned long index;
unsigned long value;
};
WX_DECLARE_EXPORTED_HASH_MAP(unsigned long, wxImageHistogramEntry,
wxIntegerHash, wxIntegerEqual,
wxImageHistogram);
\end{verbatim}
\wxheading{Return value}
Returns number of colours in the histogram.
