Detailed Description

this class extends DcmQuantPixel by an integer value which is used for various purposes.

The class is used as a helper class during computation of an image histogram, as a member of a color LUT and as a member of a color hash table.

Member Data Documentation

int DcmQuantHistogramItem::value [private]

integer value assigned to this pixel.

This value is used for different purposes. During computation of a histogram it is used as a counter that counts the instances of the current color. In a color hash table, it contains the index value from the color LUT assigned to this color. In a color LUT, it is the cluster value, i.e. the radius in which all color are guaranteed to be mapped to this palette color.
