template<typename TPixel >

virtual::itk::LightObject::Pointer itk::ColorTable< TPixel >::CreateAnother ( ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

template<typename TPixel >

void itk::ColorTable< TPixel >::DeleteColors ( )

private

template<typename TPixel >

unsigned int itk::ColorTable< TPixel >::GetClosestColorTableId	(	TPixel	r,
		TPixel	g,
		TPixel	b
	)

Find the color closest to a given pixel. Uses a L2 distance metric.

template<typename TPixel >

RGBPixel< TPixel > itk::ColorTable< TPixel >::GetColor ( unsigned int colorId )

Get the color stored at a given index.

template<typename TPixel >

TPixel itk::ColorTable< TPixel >::GetColorComponent	(	unsigned int	colorId,
		char	rgb
	)

Given the position in the table and the color returns the value.

template<typename TPixel >

std::string itk::ColorTable< TPixel >::GetColorName ( unsigned int colorId )

Get the name of the color at a given index.

template<typename TPixel >

virtual const char* itk::ColorTable< TPixel >::GetNameOfClass ( ) const

virtual

Run-time type information (and related methods).

Reimplemented from itk::Object.

template<typename TPixel >

virtual unsigned int itk::ColorTable< TPixel >::GetNumberOfColors ( ) const

virtual

Get the number of colors in the lookup table.

template<typename TPixel >

static Pointer itk::ColorTable< TPixel >::New ( )

static

Method for creation through the object factory.

template<typename TPixel >

void itk::ColorTable< TPixel >::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)		const

overrideprotectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::LightObject.

template<typename TPixel >

bool itk::ColorTable< TPixel >::SetColor	(	unsigned int	c,
		TPixel	r,
		TPixel	g,
		TPixel	b,
		const char *	name = `"UserDefined"`
	)

Set the color at a given index. Optionally provide a name for the color. If a name is not provided, the name "UserDefined" is used.

template<typename TPixel >

bool itk::ColorTable< TPixel >::SetColor	(	unsigned int	c,
		RGBPixel< TPixel >	pixel,
		const char *	name = `"UserDefined"`
	)

Set the color at a given index. Optionally provide a name for the color. If a name is not provided, the name "UserDefined" is used.

template<typename TPixel >

void itk::ColorTable< TPixel >::UseDiscreteColors ( )

Generate a lookup table of 8 discrete colors. The colors are Red, Purple, Aqua, Yellow, Green, Blue, Grey0.70, White. For integral pixel types, the color range is between NonpositiveMin() and max(). For continuous types, the range is 0.0 to 1.0.

template<typename TPixel >

void itk::ColorTable< TPixel >::UseGrayColors ( unsigned int n = 256 )

Generate a lookuptable of n grayscale values. For integral pixel types, a ramp is generated from NonpositiveMin() to max() of the pixel type. For continuous pixel types, the range is 0.0 to 1.0.

template<typename TPixel >

void itk::ColorTable< TPixel >::UseHeatColors ( unsigned int n = 256 )

Generate a lookup table of n values good for showing "temperatures". For integral pixel types, the color range is between NonpositiveMin() and max(). For continuous types, the range is 0.0 to 1.0.

template<typename TPixel >

void itk::ColorTable< TPixel >::UseRandomColors ( unsigned int n = 256 )

Generate a lookup table of n random values. For integral pixel types, the color range is between NonpositiveMin() and max(). For continuous types, the range is 0.0 to 1.0.
