PgVertical.gravityToRotation

Converts a #PangoGravity value to its natural rotation in radians. @gravity should not be %PANGO_GRAVITY_AUTO.

Note that pango_matrix_rotate() takes angle in degrees, not radians. So, to call pango_matrix_rotate() with the output of this function you should multiply it by (180. / G_PI).
