GlyphGeometryRef
public struct GlyphGeometryRef : GlyphGeometryProtocol
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:
- Assume the current point is (x, y)
- Render the current glyph at (x + x_offset, y + y_offset),
- Advance the current point to (x + width, y)
- Render the next glyph
The GlyphGeometryRef type acts as a lightweight Swift reference to an underlying PangoGlyphGeometry instance.
It exposes methods that can operate on this data type through GlyphGeometryProtocol conformance.
Use GlyphGeometryRef only as an unowned reference to an existing PangoGlyphGeometry instance.
