XFontSetExtents(3)

💖 NAME 💖

okay so bestie, welcome to XFontSetExtents(3) from the XLIB FUNCTIONS section — this page is literally about the XFontSetExtents structure, and it's giving extremely specific rectangle energy ✨

XFontSetExtents — the XFontSetExtents structure. no cap, that's the whole name vibe 🫶

---

🧚 STRUCTURES 🧚

so the XFontSetExtents structure contains this exact little icon:

typedef struct {
        XRectangle max_ink_extent;      /* over all drawable characters */
        XRectangle max_logical_extent;  /* over all drawable characters */
} XFontSetExtents;

the XRectangle structures used to return font set metrics are the usual Xlib screen-oriented rectangles, bestie: x and y give the upper left corner, and width and height are always positive 🎀

• max_ink_extent — this member gives the maximum extent, over all drawable characters, of the rectangles that bound the character glyph image drawn in the foreground color, relative to a constant origin. for the detailed semantics, see XmbTextExtents and XwcTextExtents 👀
• max_logical_extent — this member gives the maximum extent, over all drawable characters, of the rectangles that specify minimum spacing to other graphical features, relative to a constant origin. other graphical features drawn by the client — for example, a border surrounding the text — should not intersect this rectangle. the max_logical_extent member should be used to compute minimum interline spacing and the minimum area that must be allowed in a text field to draw a given number of arbitrary characters 💅

⚠️ caveat time, bestie: due to context-dependent rendering, appending a given character to a string may change the string's extent by an amount other than that character's individual extent. literally not me making the rules, that's just the tea 😭
