Class GlyphGeometry

java.lang.Object
org.javagi.base.ProxyInstance
org.gnome.pango.GlyphGeometry
All Implemented Interfaces:
Proxy
@Generated("org.javagi.JavaGI") public class GlyphGeometry extends ProxyInstance

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 xOffset 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
