Convert a blurhash into an image URI. The float parameter is the punch, used to increase/decrease contrast of the resulting image

punch : Float
punch =
    0.9


hash : String
hash =
    "LGFFaXYk^6#M@-5c,1J5@[or[Q6."


BlurHash.toUri { width = 3, height = 3 } punch hash
-->  "data:image/bmp;base64,Qk1aAAAAAAAAADYAAAAoAAAAAwAAAAMAAAABABgAAAAAACQAAAATCwAAEwsAAAAAAAAAAAAAmp6Rr5BTZXaAAAAAsoyUvoRlY22PAAAAo3etuXWZiliIAAAA"

Encode an array of pixel colors as a blurhash

import Color exposing (Color)
import Array exposing (Array)


pixels : Array Color
pixels =
    Array.initialize 25 (\i -> Color.rgb255 i i i)


mask : { width : Int, height : Int }
mask =
    { width = 4, height = 4 }


fromPixels mask { rows = 5, columns = 5 } pixels
    --> "U01fC^t7WB%MIUWBayWBIUWBfQWB%Mj[ayof"
