XcmsCIELuvQueryMaxC, XcmsCIELuvQueryMaxL, XcmsCIELuvQuer- yMaxLC, XcmsCIELuvQueryMinL - obtain the CIE L*u*v* coordi- nates

Status XcmsCIELuvQueryMaxC(XcmsCCCccc, XcmsFloathue_angle, XcmsFloatL_star, XcmsColor *color_return); Status XcmsCIELuvQueryMaxL(XcmsCCCccc, XcmsFloathue_angle, XcmsFloatchroma, XcmsColor *color_return); Status XcmsCIELuvQueryMaxLC(XcmsCCCccc, XcmsFloathue_angle, XcmsColor *color_return); Status XcmsCIELuvQueryMinL(XcmsCCCccc, XcmsFloathue_angle, XcmsFloatchroma, XcmsColor *color_return);

cccSpecifies the CCC. Note that the CCC's Client White Point and White Point Adjustment procedures are ignored.chromaSpecifies the chroma at which to find maximum lightness (MaxL) or minimum lightness (MinL). or minimum lightness (MinL) or hue angle (MaxLC)color_returnReturns the CIE L*u*v* coordinates of maximum chroma (MaxC and MaxLC), maximum lightnes (MaxL), 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_angleSpecifies the hue angle (in degrees) at which to find maximum chroma (MaxC and MaxLC), maximum lightness (MaxL),.L_starSpecifies the lightness (L*) at which to find max- imum chroma (MaxC) or maximum lightness (MaxL).

TheXcmsCIELuvQueryMaxCfunction, 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. TheXcmsCIELuvQueryMaxLfunction, 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 XFree86 Version 4.5.0 1 XcmsCIELuvQueryMaxC(3X11)XLIB FUNCTIONS XcmsCIELuvQueryMaxC(3X11) point in CIE L*u*v* coordinates. AnXcmsFailurereturn value usually indicates that the given chroma is beyond maximum for the given hue angle. TheXcmsCIELuvQueryMaxLCfunction, given a hue angle, finds the point of maximum chroma displayable by the screen. It returns this point in CIE L*u*v* coordinates. TheXcmsCIELuvQueryMinLfunction, given a hue angle and chroma, finds the point of minimum lightness (L*) display- able by the screen. It returns this point in CIE L*u*v* coordinates. AnXcmsFailurereturn value usually indicates that the given chroma is beyond maximum for the given hue angle.
