README
blurhash.cr 
A pure Crystal implementation of Blurhash. The API is stable, however the hashing function in either direction may not be.
Blurhash is an algorithm written by Dag Ågren for Wolt (woltapp/blurhash) that encodes an image into a short (~20-30 byte) ASCII string. When you decode the string back into an image, you get a gradient of colors that represent the original image. This can be useful for scenarios where you want an image placeholder before loading, or even to censor the contents of an image à la Mastodon.
Currently supports PNG and JPEG file types.
