NAME
XcmsTekHVCQueryMaxC, XcmsTekHVCQueryMaxV, XcmsTekHVCQueryMaxVC, Xcm-
sTekHVCQueryMaxVSamples, XcmsTekHVCQueryMinV - obtain the TekHVC coordi-
nates
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 spec-
ification 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 unde-
fined.
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 re-
turns 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 re-
turns the maximum Value and the actual Hue and Chroma at which the maxi-
mum 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 re-
turns the minimum Value and the actual Hue and Chroma at which the mini-
mum Value was found.
