- 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 lightness (MaxL) or
minimum lightness (MinL). or minimum lightness (MinL) or hue angle (MaxLC)
- color_return
- Returns the CIE L*u*v* coordinates of c displayable by the
screen for the given hue angle and lightness (MaxC), hue angle and chroma
(MaxL and MinL), . 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)
- hue_angle
- Specifies the hue angle (in degrees)
at which to find maximum chroma (MaxC and MaxLC), maximum lightness (MaxL),
.
- L_star
- Specifies the lightness (L*) at which to find s.
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*) 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.
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.
