void pcl::visualization::FloatImageUtils::getColorForAngle	(	float	value,
		unsigned char &	r,
		unsigned char &	g,
		unsigned char &	b
	)		`[static]`

Get RGB color values for a given float in [-PI, PI] or special cases like -INFINITY(light green), INFINITY(light blue), NAN(light red) The colors are black(-PI) -> blue(-PI/2) -> white(0) -> green(PI/2) -> black(PI) with accordant values in between

void pcl::visualization::FloatImageUtils::getColorForFloat	(	float	value,
		unsigned char &	r,
		unsigned char &	g,
		unsigned char &	b
	)		`[static]`

Get RGB color values for a given float in [0, 1] or special cases like -INFINITY(light green), INFINITY(light blue), NAN(light red)

void pcl::visualization::FloatImageUtils::getColorForHalfAngle	(	float	value,
		unsigned char &	r,
		unsigned char &	g,
		unsigned char &	b
	)		`[static]`

Get RGB color values for a given float in [0, PI] or special cases like -INFINITY(light green), INFINITY(light blue), NAN(light red) The colors are black(-PI/2) -> blue(-PI/4) -> white(0) -> green(PI/4) -> black(PI/2) with accordant values in between

unsigned char * pcl::visualization::FloatImageUtils::getVisualAngleImage	(	const float *	angle_image,
		int	width,
		int	height
	)		`[static]`

Use getColorForAngle for all elements of the given arrays.

unsigned char * pcl::visualization::FloatImageUtils::getVisualHalfAngleImage	(	const float *	angle_image,
		int	width,
		int	height
	)		`[static]`

Use getColorForHalfAngle for all elements of the given arrays.

unsigned char * pcl::visualization::FloatImageUtils::getVisualImage	(	const float *	float_image,
		int	width,
		int	height,
		float	min_value = `-std::numeric_limits<float>::infinity ()`,
		float	max_value = `std::numeric_limits<float>::infinity ()`,
		bool	gray_scale = `false`
	)		`[static]`

Use getColorForFloat for all elements of the given arrays, whereas the values are first normalized to [0,1], either using the given min/max values or based on the actual minimal and maximal values existing in the array. The output is a byte array of size 3*width*height containing the colors in RGB order. If gray_scale is true, the outcome will still be an RGB image, but all colors apart for the special colors of non-finite numbers, will be gray values

unsigned char * pcl::visualization::FloatImageUtils::getVisualImage	(	const unsigned short *	float_image,
		int	width,
		int	height,
		unsigned short	min_value = `0`,
		unsigned short	max_value = `std::numeric_limits<unsigned short>::max ()`,
		bool	gray_scale = `false`
	)		`[static]`

Use getColorForFloat for all elements of the given arrays, whereas the values are normalized to [0,1] with the given min/max values. The output is a byte array of size 3*width*height containing the colors in RGB order. If gray_scale is true, the outcome will still be an RGB image, but all colors will be gray values.
