Display blurhash
toUri : { width : Basics.Int, height : Basics.Int } -> Basics.Float -> String -> String
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."
