View Source Scenic.Primitive.Sector (Scenic v0.11.2)
Draw an sector on the screen.
An sector is a shape that looks like a piece of pie.
data
Data
{radius, angle}
The data for an Sector is a tuple.
radius- the radius of the Sectorangle- the angle the Sector is swept through in radians
note
Note
The format for Sector has changed since v0.10. It used to be {radius, start_angle, end_angle}. You can achieve the same effect in the new, simpler format by using the same radius and the new angle is the difference between the old end_angle and start_angle. Then you can apply a rotation transform to get it in the right position.
styles

This primitive recognizes the following styles
hidden- show or hide the primitivescissor- "scissor rectangle" that drawing will be clipped to.fill- fill in the area of the primitivestroke- stroke the outline of the primitive. In this case, only the curvy part.
