Member Function Documentation

bool ColorMapping::addColor

(

double

x

)

Adds a new Color at a place between 0,1. The new color node has default values.

Parameters:

x

place of the new color node, between 0,1.

Returns:

true if the operation was successful

bool ColorMapping::removeColor

(

int

i

)

Removes a color at a certain counter.

Parameters:

i

count of the color node to remove.

Returns:

true if the operation was successful

void ColorMapping::moveColor	(	int	i,
		double	x
	)

Moves a certain color to another place.

Parameters:

	i	count of the color node to be moved
	x	new place of the color node

void ColorMapping::setColor	(	int	i,
		int	r,
		int	g,
		int	b
	)

Sets the color of a node of a certain count.

Parameters:

	i	count of the color node to be altered
	r	new red value
	g	new green value
	b	new blue balue

Color ColorMapping::getColor

(

int

i

)

Returns the color of a the color node at a certain count.

Parameters:

i

count of the color node

Returns:

the desired color

Color ColorMapping::getColorAt

(

double

x

)

Returns the interpolated color at a place between 0,1 in dependence of the other color nodes.

Parameters:

x

value of the color map, between 0,1

Returns:

the desired color

void ColorMapping::resetColorIter

(

)

Resets the color iterator.

bool ColorMapping::hasNextColor

(

)

Returns if there are any colors left relative to the iterator.

Returns:

true if there is any color left

Color ColorMapping::getNextColor

(

)

Returns the color of the iterator and increases the iterator.

Returns:

the next color of the iterator

void ColorMapping::init	(	Color	c1,
		Color	c2
	)			[private]

This method is called by the constructors to initialize the color map.
