Detailed Description

This class encapsulates the functionality of the histogram together with the transfer function.

Constructor & Destructor Documentation

Hist_Transfer::Hist_Transfer

(

QWidget *

parent = 0

)

Constructs a new Transfer Function Histogram Object

---

Member Function Documentation

unsigned int Hist_Transfer::getClassCt

(

)

Returns the number of classes the histogram consists of

float * Hist_Transfer::getTexture

(

)

Returns the assembled data required for the construction of a 1D Texture containing the transfer functions values

void Hist_Transfer::loadFunction

(

QDataStream &

fileHandle

)

This function reads the transfer function at the given point of the filestream passed, identified by 'fileHandle'

void Hist_Transfer::printFunction

(

QDataStream &

fileHandle

)

This function streams the transfer function at the given point to the filestream passed, identified by 'fileHandle'

void Hist_Transfer::setHistogram

(

)

Calculates the histogram for the data actually stored

void Hist_Transfer::setKnotColor	(	int	label,
		QColor	color
	)

Sets the color for the actual chosen knot identified by 'label' to the color 'color'

void Hist_Transfer::setScanData	(	unsigned short *	scanData,
		unsigned int	size
	)

Sets up the volumetric data this widget should operate on, where 'scanData' points to an array of 1 dimensional data with the given size 'size'

void Hist_Transfer::updateHist	(	unsigned int	x,
		unsigned int	y
	)

Inserts a new knot into the transfer function or moves an existing knot, depending on the distance between the mouse position '(x,y)' and the nearest knot
