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.

NrOfComponents

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]

GetDescriptor()

void AOI_ColorSpace_ICC::GetDescriptor

(

char *

desc

)

const

Gets the description used by the ICC profile that is hold by this colorspace object.

Parameters

desc	String to hold the description of the ICC profile. Needs to be 256 bytes long.

Definition at line 281 of file AOI_ColorSpace.cpp.

GetHeader()

const icHeader & AOI_ColorSpace_ICC::GetHeader

(

)

const

Returns the ICC header of the ICC profile that is hold by this colorspace object.

Returns

icHeader of the ICC profile used.

Definition at line 270 of file AOI_ColorSpace.cpp.

GetICCData()

void AOI_ColorSpace_ICC::GetICCData

(

uint8_t *

data

)

const

Gets the ICC profile that is hold by this colorspace object. The size of the buffer can be retrieved by inspecting icHeader.size retrieved using GetHeader.

Parameters

data	Buffer to hold raw ICC profile data.

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.

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.
