Blurhash.SkiaSharp

A Blurhash implementation based on blurhash.net for SkiaSharp, thus fully available for Xamarin and other .NET Standard 2.0 platforms.

Currently allows to decode a blurhash into SKBitmap or encode a SKBitmap into Blurhash string.

Several portions of the code are directly copy-pasted from the System.Drawing implementation.

Tested on Xamarin.Forms on UWP, iOS and Android.

Example usage

Displaying a placeholder for an image in Xamarin.Forms Image control

// decode blurhash instring into a SKBitmap
var im = Blurhash.SkiaSharp.Blurhasher.Decode("LEHV6nWB2yk8pyo0adR*.7kCMdnj", 219, 176);

// load it into a SKImage
var data = SKImage.FromBitmap(im).Encode();

// use as a source for Image control
image1.Source = ImageSource.FromStream(data.AsStream);

Encoding an resource image into a Blurhash string

// get the image from resources
var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("TestMobileApp.noah.jpg");

// load to SKImage and to Image control
var img = SKImage.FromEncodedData(stream);
image1.Source = ImageSource.FromFile("noah.jpg");

// create SKBitmap from Image and create a blurhash for it
var hash = Blurhash.SkiaSharp.Blurhasher.Encode(SKBitmap.FromImage(img), 4, 3);

// and show it in a Editor control
editor1.Text = hash;
