Polyline with multiple segments

[ashwanirathee]

There is a method for making a line in ImageDraw.jl but the method for making a continued lines with multiple points given in arguments in not yet present.I believe single line isn't that useful and having ability to make poly line with continuous vertices/points mentioned in arguments could prove to be quite useful.Better yet if the polyline argument could be provided in vector or similar form.

• It has implementation in MATLAB(mentioned in api reference),matlab also has implementations for poly-polygons(circle and rectangle) but I can't think of their uses yet
• Skimage has interesting implementation of Line in n directions: https://scikit-image.org/docs/dev/api/skimage.draw.html#skimage.draw.line_nd

Path kind of implements what I am looking for here

#Path methods

Path(v::AbstractVector{Tuple{Int, Int}}) = Path([Point(p...) for p in v])
Path(v::AbstractVector{CartesianIndex{2}}) = Path([Point(p) for p in v])

function draw!(img::AbstractArray{T, 2}, path::Path, color::T) where T<:Colorant
    vertices = [CartesianIndex(p.y, p.x) for p in path.vertices]
    for i in 1:length(vertices)-1
		draw!(img, LineSegment(vertices[i], vertices[i+1]), color)
    end
	img
end
