 ## Visual clipping
 
 Use [`clip`](@ref) to turn the current path into a clipping region, masking any graphics outside the path. [`clippreserve`](@ref) keeps the current path, but also uses it as a clipping region. [`clipreset`](@ref) resets it. `:clip` is also an action for drawing functions like [`circle`](@ref).

+A polygon is an ordered collection of Points stored in an array. To draw a polygon, you can use the [`poly()`](@ref) function, which converts the points to a path.
 
 A path is a sequence of one or more straight and curved (circular arc or Bézier curve) segments. Paths can consist of subpaths. Luxor maintains a 'current path', to which you can add lines and curves until you finish with a stroke or fill instruction.
