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.
