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

Draw an ellipse on the screen.

Data

{radius_1, radius_2}

The data for an arc is a single number.

radius_1 - the radius of the ellipse in one direction
radius_2 - the radius of the ellipse in the other direction

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.

Note: you can achieve the same effect with a Circle primitive by applying a :scale transform to it with unequal values on the axes

Usage

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

graph
  |> ellipse( {75, 100}, stroke: {1, :yellow} )
