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)

Definition at line 50 of file float_image_utils.cpp.

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.

Definition at line 222 of file float_image_utils.cpp.

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

Use getColorForHalfAngle for all elements of the given arrays.

Definition at line 241 of file float_image_utils.cpp.

unsigned char * pcl_visualization::FloatImageUtils::getVisualImage	(	const float *	floatImage,
		int	width,
		int	height,
		float	minValue = -std::numeric_limits<float>::infinity (),
		float	maxValue = std::numeric_limits<float>::infinity (),
		bool	grayScale = 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 grayScale 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
