💖 XcmsCIELuvQueryMaxC(3) 💖

okay so bestie, this is the XLIB FUNCTIONS page for XcmsCIELuvQueryMaxC(3). It's giving “four query functions walk into a color space” and they're all here to obtain the CIE L*u*v* coordinates. No cap, that's the whole mission. ✨

🌸 NAME 🌸

XcmsCIELuvQueryMaxC, XcmsCIELuvQueryMaxL, XcmsCIELuvQueryMaxLC, and XcmsCIELuvQueryMinL — obtain the CIE L*u*v* coordinates. That's the whole lineup, bestie. 💅

✨ SYNTAX ✨

Here are the exact call shapes, so copy them with your whole chest:

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. iconic lowkey hand-wave behavior, but that's the spec.
• chroma — Specifies the chroma at which to find maximum lightness (MaxL) or minimum lightness (MinL).
• color_return — Returns the CIE L*u*v* coordinates 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. so yeah, don't go trusting that pixel member, bestie 🫶
• hue_angle — Specifies the hue angle (in degrees) at which to find maximum chroma (MaxC and MaxLC), maximum lightness (MaxL), or minimum lightness (MinL).
• 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. maximum chroma behavior, slay ✨

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. that's your little “you asked for too much chroma” warning, iykyk.

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. no chroma input needed — it's built different 🌈

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. same “chroma said too much” situation, just on the minimum-lightness side.

okay that's the whole page, bestie! 💖 This one comes from X Version 11, libX11 1.8.14, and the footer didn't print a separate date, so I'm not inventing one — no fake metadata on my watch. XcmsCIELuvQueryMaxC(3) signing off. 🫶✨🎀
