Enumeration
PangoGravity
since: 1.16
Description [src]
PangoGravity represents the orientation of glyphs in a segment
of text.
This is useful when rendering vertical text layouts. In those situations,
the layout is rotated using a non-identity PangoMatrix, and then
glyph orientation is controlled using PangoGravity.
Not every value in this enumeration makes sense for every usage of
PangoGravity; for example, PANGO_GRAVITY_AUTO only can be passed to
pango_context_set_base_gravity() and can only be returned by
pango_context_get_base_gravity().
