Member Function Documentation

get_ColorMap()

ddt::colorMap_t * ImageColor::get_ColorMap

(

std::string

color_map_name

)

Get a color map array, identified by the color map name

Parameters

color_map_name

the name of the color map (taken from the color map file name)

Returns

a colorMap object (an array of 256 RGB triples (array of 3 float values, representing the red, green and blue part, all expressed as a value between 0.0 and 1.0)

get_ColorMapARGB()

ddt::colorMapARGB_t * ImageColor::get_ColorMapARGB

(

std::string

color_map_name

)

Get a color map array, identified by the color map name

Parameters

color_map_name

the name of the color map (taken from the color map file name)

Returns

a colorMapARGB object (an array of 256 unsigned int values, each value representing an alpha channel and the red, green and blue parts, all expressed as a values between 0 and 255)

get_ColorMapsList()

std::list< std::string > ImageColor::get_ColorMapsList

(

)

Returns a list of all loaded colormaps

Returns

list containing the names of all loaded colormaps

get_GrayScaleColorMap()

ddt::colorMap_t * ImageColor::get_GrayScaleColorMap

(

)

Get a default gray scale color map array

Returns

a colorMap object (an array of 256 RGB triples (array of 3 float values, representing the red, green and blue part, all expressed as a value between 0.0 and 1.0)

get_GrayScaleColorMapARGB()

ddt::colorMapARGB_t * ImageColor::get_GrayScaleColorMapARGB

(

)

Get a default gray scale color map array

Returns

a colorMapARGB object (an array of 256 unsigned int values, each value representing an alpha channel and the red, green and blue parts, all expressed as a values between 0 and 255)

get_LinearScalingLut()

ddt::scalingLut_t * ImageColor::get_LinearScalingLut	(	const double	cut_level_min,

Parameters

cut_level_min	the minimum cut level to be applied for the LUT creation
cut_level_max	the minimum cut level to be applied for the LUT creation

Returns

a scalingLut object (an array of 64K uint values)

get_LogarithmicScalingLut()

ddt::scalingLut_t * ImageColor::get_LogarithmicScalingLut	(	const double	cut_level_min,
		const double	cut_level_max
	)

Get the LUT for logarithmic color scaling

Parameters

cut_level_min	the minimum cut level to be applied for the LUT creation
cut_level_max	the minimum cut level to be applied for the LUT creation

Returns

a scalingLut object (an array of 64K uint values)

get_SqrtScalingLut()

ddt::scalingLut_t * ImageColor::get_SqrtScalingLut	(	const double	cut_level_min,
		const double	cut_level_max
	)

Parameters

cut_level_min	the minimum cut level to be applied for the LUT creation
cut_level_max	the minimum cut level to be applied for the LUT creation

Returns

a scalingLut object (an array of 64K uint values)
