SYNTAX
Status XcmsTekHVCQueryMaxC(XcmsCCC ccc, XcmsFloat hue, XcmsFloat value,
XcmsColor *color_return);
Status XcmsTekHVCQueryMaxV(XcmsCCC ccc, XcmsFloat hue, XcmsFloat
chroma, XcmsColor *color_return);
Status XcmsTekHVCQueryMaxVC(XcmsCCC ccc, XcmsFloat hue, XcmsColor
*color_return);
Status XcmsTekHVCQueryMaxVSamples(XcmsCCC ccc, XcmsFloat hue, XcmsColor
colors_return[], unsigned int nsamples);
Status XcmsTekHVCQueryMinV(XcmsCCC ccc, XcmsFloat hue, XcmsFloat
chroma, XcmsColor *color_return);
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.
