Constructor & Destructor Documentation

DiCIELABFunction::DiCIELABFunction	(	const char *	filename,
		const E_DeviceType	deviceType = EDT_Monitor,
		const signed int	ord = -1
	)

constructor, read device characteristics file.

Keywords: "max" for maximum DDL (Device Driving Level, required at first position) "amb" for ambient light and "lum" for illumination (both optional) "ord" for the order of the polynomial curve fitting algorithm used to interpolate the given base points (0 or absent = use cubic spline interpolation)

Parameters:

filename	name of the characteristics file (luminance/OD for each DDL)
deviceType	type of the output device (default: monitor)
ord	order of the polynomial curve fitting algorithm used to interpolate the given base points (-1 = use file setting, 0 = cubic spline)

DiCIELABFunction::DiCIELABFunction	(	const double *	val_tab,
		const unsigned long	count,
		const Uint16	max = 255,
		const E_DeviceType	deviceType = EDT_Monitor,
		const signed int	ord = 0
	)

constructor, use given array of luminance/OD values.

UNTESTED Values must be sorted and complete (i.e. there must be an entry for each DDL) The given arrays are copied internally.

Parameters:

val_tab	pointer to array with luminance/OD values
count	number of array elements (should be equal to 'max + 1')
max	maximum DDL (device driving level)
deviceType	type of the output device (default: monitor)
ord	order of the polynomial curve fitting algorithm used to interpolate the given base points (0 or negative = use cubic spline interpolation)

DiCIELABFunction::DiCIELABFunction	(	const Uint16 *	ddl_tab,
		const double *	val_tab,
		const unsigned long	count,
		const Uint16	max = 255,
		const E_DeviceType	deviceType = EDT_Monitor,
		const signed int	ord = 0
	)

constructor, use given array of DDL and luminance values.

UNTESTED Values will be automatically sorted and missing values will be interpolated. The given arrays are copied internally.

Parameters:

ddl_tab	pointer to array with DDL values (must be with the interval 0..max)
val_tab	pointer to array with luminance/OD values
count	number of array elements (2..65536)
max	maximum DDL (device driving level)
deviceType	type of the output device (default: monitor)
ord	order of the polynomial curve fitting algorithm used to interpolate the given base points (0 or negative = use cubic spline interpolation)

DiCIELABFunction::DiCIELABFunction	(	const double	val_min,
		const double	val_max,
		const unsigned long	count = 256,
		const E_DeviceType	deviceType = EDT_Monitor,
		const signed int	ord = 0
	)

constructor, compute luminance/OD values automatically within the specified range.

Parameters:

val_min	minimum luminance/OD value
val_max	maximum luminance/OD value
count	number of DDLs (device driving level, 1..65536))
deviceType	type of the output device (default: monitor)
ord	order of the polynomial curve fitting algorithm used to interpolate the given base points (0 or negative = use cubic spline interpolation)

Member Function Documentation

DiDisplayLUT* DiCIELABFunction::getDisplayLUT

(

unsigned long

count

)

[protected, virtual]

create CIELAB LUT with specified number of entries

Parameters:

count

number of LUT entries

Returns:

pointer to created LUT if successful, NULL otherwise

Implements DiDisplayFunction.

int DiCIELABFunction::writeCurveData	(	const char *	filename,
