gsk:path-point-rotation (point path direction)

point -- a gsk:path-point instance
path -- a gsk:path instance with the path that point is on
direction -- a gsk:path-direction value with the direction for which to return the rotation

The float with the angle between the tangent and the X axis, in degrees.

Gets the direction of the tangent at a given point. This is a convenience variant of the gsk:path-point-tangent function that returns the angle between the tangent and the X axis. The angle can, for example, be used in the gtk:snapshot-rotate function.
