Image Blur

Generates base64 encoded, downscaled and blurred versions of media library’s images, which can be used f.e. as a placeholder. Inspiration After Wolt showcased their Blurhash 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. How to start using the plugin Install and activate this plugin in your environment The plugin should generate blurs for each image on the activation. Check an image’s details in your media library. It should have listing of all generated blurs. To get a blur to a template, use get_post_meta(). Check example theme in plugin’s repository Customization 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: 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");
