[Insight-users] Histogram modification - troubles with SetFrequency

[sacrif]

Hi, I finally found out what the problem is. The histogram is defined as
const HistogramType * histogram; or HistogramType::ConstPointer histogram;

However the SetFrequency method is a not const method. Therefore non of the
4 SetFrequency methods is applicable on it.

The problem is that the GetOutput() method of the
itk::Statistics::ScalarImageToHistogramGenerator class returns a "const
HistogramType *" which I assign to my "const HistogramType* histogram"
pointer. So I can only define the histogram as const. But then the
SetFrequency would not work. (and results in the compilation error: error
C2663: 'itk::Statistics::Histogram<TMeasurement>::SetFrequency' : 4
overloads have no legal conversion for 'this' pointer...<--as written in my
previous post)

Is it possible that a histogram as I defined it can't be changed as soon as
it is created? Somehow I can't imagine this is the case. But at the moment I
can only imagine to write the values in an std::vector to proceed working on
it.
I would appreciate any onther advice.

Thank you & kind regards
