Scenic.Primitive.Sector (Scenic v0.11.0-beta.0) View Source

Draw an sector on the screen.

An sector is a shape that looks like a piece of pie.

Data

{radius, angle}

The data for an Sector is a tuple.

radius - the radius of the Sector
angle - the angle the Sector is swept through in radians

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 primitive
fill - fill in the area of the primitive
stroke - stroke the outline of the primitive. In this case, only the curvy part.

Usage

You should add/modify primitives via the helper functions in Scenic.Primitives

graph
  |> sector( {100, 1.5}, stroke: {1, :yellow} )
