Member Function Documentation

ChannelName()

const char * AOI_ColorSpace::ChannelName ( uint32_t channel ) const

inherited

Returns the channel name of the requested channel of the colorspace. Thus "Red" for channel 0 of RGB.

Parameters

channel

Index of the channel. Must be less than NrOfComponents

Returns

Name of the channel.

GetBlackPoint()

void AOI_ColorSpace_CalibratedRGB::GetBlackPoint

(

double

bp[3]

)

const

Retrieves the black point used by this CalibratedRGB object. The black point is defined in XYZ.

Parameters

bp	Receives the black point in XYZ.

GetWhitePoint, GetGamma

Definition at line 212 of file AOI_ColorSpace.cpp.

GetBlueColorant()

void AOI_ColorSpace_CalibratedRGB::GetBlueColorant

(

double

blue[3]

)

const

Retrieves the blue colorant used by this CalibratedRGB object. The colorant is defined in XYZ.

Parameters

blue	Receives the blue colorant in XYZ.

GetRedColorant, GetGreenColorant

Definition at line 259 of file AOI_ColorSpace.cpp.

GetCIELab()

void AOI_ColorSpace::GetCIELab ( const uint16_t * src, float * out ) const

inherited

Retrieve the CIELab color of the given channel values. The channel values are converted to CIELab D50. The conversion follows the rules as explained in the PDF colorflow diagram. When no suiteable conversion to CIELab is available default conversions will be used. For example calling this method on a AOI_ColorSpace_DeviceRGB instance will invoke the build-in generic RGB to CIELab convertor.

Parameters

src	Input channels 16 bits encoded. The number of channels must match the colorspace channel count
out	Receives the resulting L, a, b values. L [0,100], a <-128,127], b <-128,127]

Definition at line 149 of file AOI_ColorSpace.cpp.

GetGamma()

void AOI_ColorSpace_CalibratedRGB::GetGamma

(

double

gam[3]

)

const

Returns the gamma used by this CalibratedRGB object.

Parameters

gam	Receives the gamma used.

GetGreenColorant()

void AOI_ColorSpace_CalibratedRGB::GetGreenColorant

(

double

green[3]

)

const

Retrieves the green colorant used by this CalibratedRGB object. The colorant is defined in XYZ.

Parameters

green

Receives the green colorant in XYZ.

GetRedColorant, GetBlueColorant

Definition at line 247 of file AOI_ColorSpace.cpp.

GetRedColorant()

void AOI_ColorSpace_CalibratedRGB::GetRedColorant

(

double

red[3]

)

const

Retrieves the red colorant used by this CalibratedRGB object. The colorant is defined in XYZ.

Parameters

red	Receives the red colorant in XYZ.

See also

GetGreenColorant, GetBlueColorant

Definition at line 235 of file AOI_ColorSpace.cpp.

GetType()

uint32_t AOI_ColorSpace::GetType ( ) const

inherited

Class type of the colorspace. The return value is the type identifier of the colorspace class like AOI_ColorSpace_DeviceCMYK::Type for DeviceCMYK. This value is used to identify the colorspace type like CMYK, RGB, ICC, etc.

Returns

Colorspace class type.

Definition at line 97 of file AOI_ColorSpace.cpp.

GetWhitePoint()

void AOI_ColorSpace_CalibratedRGB::GetWhitePoint

(

double

wp[3]

)

const

Retrieves the white point used by this CalibratedRGB object. The white point is defined in XYZ.

Parameters

wp	Receives the white point in XYZ.

See also

GetBlackPoint, GetGamma

Definition at line 200 of file AOI_ColorSpace.cpp.

NrOfComponents()

uint32_t AOI_ColorSpace::NrOfComponents ( ) const

inherited

Returns the number of channels that is used by this colorspace. Thus 3 channels for RGB and 4 for CMYK etc.

Returns

Number of channels used by the colorspace.

Definition at line 120 of file AOI_ColorSpace.cpp.

Space()

AOI_ColorSpaceEnum AOI_ColorSpace::Space ( ) const

inherited

Colorspace used by the colorspace object. Multiple colorspace objects might return the same colorspace. For example DeviceRGB, CalibratedRGB and a RGB ICC profile all return AOI_RGBSpace.

Returns

Colorspace used by the object.
