XcmsColor(3)

🌈 XcmsColor(3) — XLIB FUNCTIONS energy ✨

Okay so this is the XcmsColor(3) page from the XLIB FUNCTIONS manual, and it's literally the color-structure lore. Come get your structs, bestie. 💖

💖 NAME 💖

• XcmsColor, XcmsRGB, XcmsRGBi, XcmsCIEXYZ, XcmsCIEuvY, XcmsCIExyY, XcmsCIELab, XcmsCIELuv, XcmsTekHVC, XcmsPad — the Xcms color structure. Periodt. ✨

🎀 STRUCTURES 🎀

The XcmsColor structure contains this exact lineup — no edits, no cap:

       typedef unsigned long XcmsColorFormat;            /* Color Specification Format */

       typedef struct {
            union {
                 XcmsRGB RGB;
                 XcmsRGBi RGBi;
                 XcmsCIEXYZ CIEXYZ;
                 XcmsCIEuvY CIEuvY;

                 XcmsPad Pad;
            } spec;
            unsigned long pixel;

            XcmsFloat a_star;

       } XcmsPad;          /* four doubles */

🦋 DESCRIPTION 🦋

The XcmsColor structure contains a union of substructures. Each substructure supports color specification encoding for a particular color space. That's it — that's the description. One main struct, a union of substructure options, and the pixel and format fields from the code above. Slay. 💅
