GOffice.BezierSpline

Fields

Name	Type	Access	Description
closed	bool	r/w	whether the curve is closed.
n	int	r/w	spline segments number.
ref_count	int	r
x	float	r/w	control points abscissa.
y	float	r/w	control points ordinates.

Methods

class	init (x, y, n, closed)
	destroy ()
	to_cairo (cr, horiz_flip)
	to_path ()

Details

class GOffice.BezierSpline

classmethod init(x, y, n, closed)

Parameters:

• x (float) – the x values

• y (float) – the y values

• n (int) – the number of x and y values

• closed (bool) – whether to return a closed curve or not

Returns:

a newly created struct GOffice.BezierSpline instance which should be destroyed by a call to GOffice.BezierSpline.destroy.

Return type:

GOffice.BezierSpline

x and y values must be valid and finite. The returned structure contains the x and y coordinates of all control points, including the incoming data. the n and closed fields are just copies of the corresponding arguments.

destroy()

Destroys the given structures after cleaning all allocated fields.

to_cairo(cr, horiz_flip)

Parameters:

• cr (cairo.Context) – a cairo context

• horiz_flip (bool) – whether to flip horizontally (for a RTL canvas).

Renders the spline in \a cr

to_path()

Returns:

a newly created GOffice.Path which should be destroyed by a call to GOffice.Path.free.

Return type:

GOffice.Path

Builds a GOffice.Path using the control points evaluated in GOffice.BezierSpline.init.
