GI.Pango.Structs.LayoutLine

The #PangoLayoutLine structure represents one of the lines resulting from laying out a paragraph via PangoLayoutLine structures are obtained by calling pango_layout_get_line() and are only valid until the text, attributes, or settings of the parent #PangoLayout are modified.

Routines for rendering PangoLayout objects are provided in code specific to each rendering system.
