Gravity.toRotation
double toRotation(pango.types.Gravity gravity)Converts a pango.types.Gravity value to its natural rotation in radians.
Note that pango.matrix.Matrix.rotate takes angle in degrees, not radians. So, to call pango.matrix.Matrix with the output of this function you should multiply it by (180. / G_PI).
Parameters
gravity | gravity to query, should not be pango.types.Gravity.Auto |
Returns
the rotation value corresponding to gravity.
