ARGUMENTS
ccc
Specifies the CCC.
Note that the CCC's Client White Point and White Point Adjustment procedures
are ignored.
chroma
Specifies the chroma at which to find maximum Value (MaxV).
colors_return
Returns nsamples of color specifications in XcmsTekHVC
such that the Chroma is the maximum attainable for the Value and Hue.
The white point associated with the returned
color specification is the Screen White Point.
The value returned in the pixel member is undefined.
color_return
Returns the maximum Chroma along with the actual Hue and Value (MaxC), maximum Value along with the Hue and Chroma (MaxV), color specification in XcmsTekHVC for the maximum Chroma, the Value at which that maximum Chroma is reached and actual Hue (MaxVC) or minimum Value and the actual Hue and Chroma (MinL) at which the maximum Chroma (MaxC and MaxVC), maximum Value (MaxV), or minimum Value (MinL) was found.
The white point associated with the returned
color specification is the Screen White Point.
The value returned in the pixel member is undefined.
hue
Specifies the Hue in which to find the maximum Chroma (MaxC and MaxVC), maximum Value (MaxV), the maximum Chroma/Value samples (MaxVSamples), or the minimum Value (MinL).
nsamples
Specifies the number of samples.
value
Specifies the Value in which to find the maximum Chroma (MaxC) or minimum Value (MinL).
DESCRIPTION
The
XcmsTekHVCQueryMaxC
function, given a Hue and Value,
determines the maximum Chroma in TekHVC color space
displayable by the screen.
It returns the maximum Chroma along with the actual Hue
and Value at which the maximum Chroma was found.
The
XcmsTekHVCQueryMaxV
function, given a Hue and Chroma,
determines the maximum Value in TekHVC color space
displayable by the screen.
It returns the maximum Value and the actual Hue and Chroma
at which the maximum Value was found.
The
XcmsTekHVCQueryMaxVC
function, given a Hue,
determines the maximum Chroma in TekHVC color space displayable by the screen
and the Value at which that maximum Chroma is reached.
It returns the maximum Chroma,
the Value at which that maximum Chroma is reached,
and the actual Hue for which the maximum Chroma was found.
The
XcmsTekHVCQueryMaxVSamples
returns nsamples of maximum Value, the Chroma at which that maximum Value
is reached, and the actual Hue for which the maximum Chroma was found.
These sample points may then be used to plot the maximum Value/Chroma
boundary of the screen's color gamut for the specified Hue in TekHVC color
space.
The
XcmsTekHVCQueryMinV
function, given a Hue and Chroma,
determines the minimum Value in TekHVC color space displayable by the screen.
It returns the minimum Value and the actual Hue and Chroma at which
the minimum Value was found.
