XcmsTekHVCQueryMaxC, XcmsTekHVCQueryMaxV, XcmsTekHVCQueryMaxVC, XcmsTekHVCQueryMaxVSamples, XcmsTekHVCQueryMinV - obtain the TekHVC coordinates

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);

ccc 1i Specifies the CCC. Note that the CCC's Client White Point and White Point Adjustment procedures are ignored.

chroma 1i Specifies the chroma at which to find \*(Ch.

colors_return 1i 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 1i Returns the \*(Lc at which the \*(lC 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 1i Specifies the Hue \*(Hu.

nsamples 1i Specifies the number of samples.

value 1i Specifies the Value in which to find the \*(Va.

The .ZN 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 .ZN 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 .ZN 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 .ZN 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 .ZN 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.
