<h2>Overview:</h2>
Blurhash is a library that allows developers to display blurred placeholder previews while images are loading. Instead of showing boring grey boxes, Blurhash provides a compact representation of a placeholder for an image. This library can be used in React Native projects and supports encoding images to blurhashes directly within the app.
<h2>Features:</h2>
<ul>
<li>Compact Placeholder: Blurhash provides a compact representation of a placeholder for an image.</li>
<li>Blurred Preview: Instead of displaying boring grey little boxes while the image loads, show a blurred preview until the full image has been loaded.</li>
<li>Expo Compatible: Can be used with development builds in Expo projects without requiring a config plugin.</li>
<li>Average Color: Retrieve the average color of the given Blurhash using the <code>getAverageColor</code> function.</li>
<li>Native Image Encoder: Includes a native Image encoder for encoding images to blurhashes directly within the React Native app.</li>
<li>Validation: Validate a blurhash string using the <code>isValidBlurhash</code> function.</li>
<li>Performance Optimization: Decoders are optimized for fast performance, allowing easy usage in collections. Adjust decodeWidth and decodeHeight props for further optimization.</li>
<li>Asynchronous Decoding: Decode the Blurhash on a separate background thread instead of the main UI-Thread using <code>decodeAsync={true}</code>.</li>
<li>Caching: The rendered Blurhash is cached as long as the blurhash, decodeWidth, decodeHeight, and decodePunch properties remain unchanged.</li>
<li>Cosine Operations: Cosine operations are cached in memory to avoid expensive re-calculation.</li>
</ul>
