Arc objects are created using the following functions. An Arc is drawn inside an invisible rectangle by specifying the top-left corner point (x1, y1), the bottom-right corner point (x2, y2), the start angle, and the end angle in degrees.
|Arc(x1, y1, x2, y2, startAngle, endAngle)||Creates an Arc with top-left corner at x1, y1, bottom-right corner at x2, y2, startAngle (in degrees), endAngle (in degrees).
Drawing always occurs in the direction of the unit circle (i.e., counter-clockwise), for positive angles. If one or both of the angles are negative, then drawing occurs in the opposite direction of the unit circle (i.e., clockwise).
|Arc(x1, y1, x2, y2, startAngle, endAngle, color, fill, thickness)||Same as above, plus color (e.g. Color.BLACK (default), Color.ORANGE or Color(255, 0, 255), using specific RGB values), fill (boolean – default is False), and thickness (default is 1 (pixel)).|
Once an Arc has been created, it may be added to a Display.
arc1 = Arc(100, 100, 200, 200, 0, 180) d.add(arc1)
Finally, you may use the following functions:
|arc1.encloses(other)||Returns True if arc1 encloses other graphics object.|
|arc1.intersects(other)||Returns True if arc1 intersects other graphics object.|
|arc1.getX()||Returns the x coordinate (in pixels).|
|arc1.getY()||Returns the y coordinate (in pixels).|
|arc1.setX(x)||Sets the x coordinate (in pixels).|
|arc1.setY(y)||Sets the y coordinate (in pixels).|
|arc1.getPosition()||Returns the position as an (x, y) tuple. This is the top-left corner of the box that encloses the arc.|
|arc1.setPosition(x, y)||Sets the position to x, y. This is the top-left corner of the box that encloses the arc.|
