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. 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) minimum Value (MinL)
- color_return
- Returns the maximum Chroma along with the actual Hue and
Value (MaxC), at which the maximum Chroma (MaxC and MaxVC), maximum
Value (MaxV), or 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. maximum Value (MaxV), the maximum
Chroma/Value samples (MaxVSamples), or the minimum Value
(MinL)
- hue
- Specifies the Hue in which to find the maximum Chroma (MaxC
and MaxVC), .
- 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.
