Detailed Description

helper class for the Median Cut algorithm.

An object of this class maintains an array of pixel boxes which is used to determine a color look-up table of given size for a true color image.

Constructor & Destructor Documentation

DcmQuantPixelBoxArray::DcmQuantPixelBoxArray ( unsigned long entries )

constructor.

Creates an array with the given number of pixel boxes.

Parameters:

entries number of entries in array, must be > 0.

DcmQuantPixelBox& DcmQuantPixelBoxArray::operator[] ( size_t idx ) [inline]

looks up an array element

Parameters:

idx	index, must be smaller than the number of entries with which this object was initialized

void DcmQuantPixelBoxArray::sort ( unsigned long boxes )

sorts the given number of pixel boxes in the array, starting with the first array element.

The boxes are sorted in decreasing order of the "sum" member.

Parameters:

boxes number of boxes to sort, must be <= entries.
