<p>Generates base64 encoded, downscaled and blurred versions of media library’s images, which can be used f.e. as a placeholder.</p>
<h3>Inspiration</h3>
<p>After Wolt showcased their <a href="https://blurha.sh/" rel="nofollow ugc">Blurhash</a> technique, I wanted to make something similar to WordPress. Instead of encoding images to base83 like the food delivery company does, I went with base64 so development experience was easier.</p>
<h3>How to start using the plugin</h3>
<ul>
<li>Install and activate this plugin in your environment
<ul>
<li>The plugin should generate blurs for each image on the activation.</li>
</ul>
</li>
<li>Check an image’s details in your media library. It should have listing of all generated blurs.</li>
<li>To get a blur to a template, use <code>get_post_meta()</code>. Check example theme in <a href="https://github.com/AttLii/image-blur" rel="nofollow ugc">plugin’s repository</a></li>
</ul>
<h3>Customization</h3>
<p>The plugin provides few filters, so developers can modify generated blur images to their needs. By default, generated images are 8 pixels wide and passed once through gaussian blur function, which will result in roughly 250-1000 characters long string. To change these, use following hooks:</p>
<pre><code>function modify_image_blur_width( int $width ): int {
  return 15;
}
add_filter("image-blur-modify-width", "modify_image_blur_width");

function modify_gaussian_blur_strength( int $strength ): int {
  return 10;
}
add_filter("image-blur-modify-gaussian-blur-strength", "modify_gaussian_blur_strength");
</code></pre>
