Member Function Documentation

uint32 dng_color_spec::Channels

(

)

const [inline]

Number of channels used for this color transform. Three for most cameras.

void dng_color_spec::SetWhiteXY

(

const dng_xy_coord &

white

)

Setter for white point. Value is as XY colorspace coordinate.

Parameters:

white

White point to set as an XY value.

const dng_xy_coord & dng_color_spec::WhiteXY

(

)

const

Getter for white point. Value is as XY colorspace coordinate.

Return values:

XY

value of white point.

References DNG_ASSERT.

const dng_vector & dng_color_spec::CameraWhite

(

)

const

Return white point in camera native color coordinates.

Return values:

A

dng_vector with components ranging from 0.0 to 1.0 that is normalized such that one component is equal to 1.0 .

References DNG_ASSERT.

const dng_matrix & dng_color_spec::CameraToPCS

(

)

const

Getter for camera to Profile Connection Space color transform.

Return values:

A

transform that takes into account all camera calibration transforms and white point.

References DNG_ASSERT.

dng_xy_coord dng_color_spec::NeutralToXY

(

const dng_vector &

neutral

)

Return the XY value to use for SetWhiteXY for a given camera color space coordinate as the white point.

Parameters:

neutral

A camera color space value to use for white point. Components range from 0.0 to 1.0 and should be normalized such that the largest value is 1.0 .

Return values:

White

point in XY space that makes neutral map to this XY value as closely as possible.
