data

 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

 Styles

This primitive recognizes the following styles

  • hidden - show or hide the primitive
  • scissor - "scissor rectangle" that drawing will be clipped to.
  • 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
