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
entriesnumber of entries in array, must be > 0.

Member Function Documentation

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

looks up an array element

Parameters
idxindex, must be smaller than the number of entries with which this object was initialized
Returns
non-const reference to DcmQuantPixelBox struct
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
boxesnumber of boxes to sort, must be <= entries.
