ARGUMENTS
Specifies the CCC. Note that the CCC's Client White Point and White Point Adjustment procedures are ignored. Specifies the chroma at which
to find maximum lightness (MaxL) or minimum lightness (MinL). or minimum lightness (MinL) or hue angle (MaxLC) Returns the CIE L*u*v* coor-
dinates of maximum chroma (MaxC and MaxLC), maximum lightness (MaxL), or minimum lightness (MinL) displayable by the screen for the given
hue angle and lightness (MaxC), hue angle and chroma (MaxL and MinL), or hue angle (MaxLC). The white point associated with the returned
color specification is the Screen White Point. The value returned in the pixel member is undefined. or minimum lightness (MinL) Specifies
the hue angle (in degrees) at which to find maximum chroma (MaxC and MaxLC), maximum lightness (MaxL), or minimum lightness (MinL). Speci-
fies the lightness (L*) at which to find maximum chroma (MaxC) or maximum lightness (MaxL).
DESCRIPTION
The XcmsCIELuvQueryMaxC function, given a hue angle and lightness, finds the point of maximum chroma displayable by the screen. It returns
this point in CIE L*u*v* coordinates.
The XcmsCIELuvQueryMaxL function, given a hue angle and chroma, finds the point in CIE L*u*v* color space of maximum lightness (L*) dis-
playable by the screen. It returns this point in CIE L*u*v* coordinates. An XcmsFailure return value usually indicates that the given
chroma is beyond maximum for the given hue angle.
The XcmsCIELuvQueryMaxLC function, given a hue angle, finds the point of maximum chroma displayable by the screen. It returns this point in
CIE L*u*v* coordinates.
The XcmsCIELuvQueryMinL function, given a hue angle and chroma, finds the point of minimum lightness (L*) displayable by the screen. It
returns this point in CIE L*u*v* coordinates. An XcmsFailure return value usually indicates that the given chroma is beyond maximum for the
given hue angle.
