The pango-gravity enumeration 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 pango-matrix, and then glyph orientation is controlled using pango-gravity. Not every value in this enumeration makes sense for every usage of pango-gravity. For example, :auto only can be passed to the function pango-context-base-gravity and can only be returned by the function pango-context-base-gravity.

:south

Glyphs stand upright (default).

:east

Glyphs are rotated 90 degrees clockwise.

:north

Glyphs are upside-down.

:west

Glyphs are rotated 90 degrees counter-clockwise.

:auto

Gravity is resolved from the context matrix.
