NAME
 XcmsCIELuvQueryMaxC, XcmsCIELuvQueryMaxL, XcmsCIELuvQueryMaxLC, XcmsCIELuvQueryMinL - obtain the CIE L*u*v* coordinates
SYNTAX
Status XcmsCIELuvQueryMaxC(XcmsCCC ccc, XcmsFloat  hue_angle, XcmsFloat L_star, XcmsColor *color_return);
Status XcmsCIELuvQueryMaxL(XcmsCCC ccc, XcmsFloat  hue_angle, XcmsFloat chroma, XcmsColor *color_return);
Status XcmsCIELuvQueryMaxLC(XcmsCCC ccc, XcmsFloat  hue_angle, XcmsColor *color_return);
Status XcmsCIELuvQueryMinL(XcmsCCC ccc, XcmsFloat  hue_angle, 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 lightness (MaxL) or minimum lightness (MinL). or minimum lightness (MinL) or hue angle (MaxLC)
- 
color_return
- 
Returns the CIE L*u*v* coordinates of maximum chroma (MaxC and MaxLC), maximum lightness (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_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 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*) 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.
