GeezerVison is showing docs.gtk.org — Pango.GlyphGeometry

Description [src] 

struct PangoGlyphGeometry {
  PangoGlyphUnit width;
  PangoGlyphUnit x_offset;
  PangoGlyphUnit y_offset;
}

The PangoGlyphGeometry structure contains width and positioning information for a single glyph.

Note that width is not guaranteed to be the same as the glyph extents. Kerning and other positioning applied during shaping will affect both the width and the x_offset for the glyphs in the glyph string that results from shaping.

The information in this struct is intended for rendering the glyphs, as follows:

  1. Assume the current point is (x, y)
  2. Render the current glyph at (x + x_offset, y + y_offset),
  3. Advance the current point to (x + width, y)
  4. Render the next glyph.
Structure members
width: PangoGlyphUnit

The logical width to use for the the character.

x_offset: PangoGlyphUnit

Horizontal offset from nominal character position.

y_offset: PangoGlyphUnit
