Method Detail

setScaleHistogram

public void setScaleHistogram(double scale)

Description copied from interface: HistogramComputer

This value represents the percentage of the image that will be used for this process. The default value is one, that means that the entire image will be processed

Specified by:

setScaleHistogram in interface HistogramComputer

getBufferHistogram
