vivid v0.4.2 Vivid.Rasterize protocol View Source

The Rasterize protocol is responsible for converting shapes into bitmaps.

If you’re defining your own shape then you need to implement this protocol.

Example

iex> use Vivid
...> Box.init(Point.init(1,1), Point.init(4,4))
...> |> Rasterize.rasterize(Bounds.init(0,0,5,5))
#MapSet<[#Vivid.Point<{1, 1}>, #Vivid.Point<{1, 2}>, #Vivid.Point<{1, 3}>, #Vivid.Point<{1, 4}>, #Vivid.Point<{2, 1}>, #Vivid.Point<{2, 4}>, #Vivid.Point<{3, 1}>, #Vivid.Point<{3, 4}>, #Vivid.Point<{4, 1}>, #Vivid.Point<{4, 2}>, #Vivid.Point<{4, 3}>, #Vivid.Point<{4, 4}>]>
