Summary: Represents an arc shape.

Module: aspose.imaging.shapes

Full Name: aspose.imaging.shapes.ArcShape

Inheritance: IOrderedShape, PieShape

Aspose.Imaging Version: 24.6.0

Constructors

Name	Description
ArcShape()	Initializes a new instance of the ArcShape class.
ArcShape(rectangle, start_angle, sweep_angle)	Initializes a new instance of the ArcShape class.
ArcShape(rectangle, start_angle, sweep_angle, is_closed)	Initializes a new instance of the ArcShape class.

Properties

Name	Type	Access	Description
bounds	RectangleF	r	Gets the object’s bounds.
center	PointF	r	Gets the shape’s center.
end_point	PointF	r	Gets the ending shape point.
has_segments	bool	r	Gets a value indicating whether shape has segments.
is_closed	bool	r/w	Gets or sets a value indicating whether ordered shape is closed. When processing closed ordered shape the starting and ending points have no meaning.
left_bottom	PointF	r	Gets the left bottom rectangle point.
left_top	PointF	r	Gets the left top rectangle point.
rectangle_height	double	r	Gets the rectangle height.
rectangle_width	double	r	Gets the rectangle width.
right_bottom	PointF	r	Gets the right bottom rectangle point.
right_top	PointF	r	Gets the right top rectangle point.
segments	ShapeSegment[]	r	Gets the shape segments.
start_angle	float	r/w	Gets or sets the start angle.
start_point	PointF	r	Gets the starting shape point.
sweep_angle	float	r/w	Gets or sets the sweep angle.

Methods
