What it does
Colorify.js is a JavaScript library for extracting image colours and applying them within a page. It can create image-based gradients, load image lists and control reveal animations. The code is available under the ISC licence.
A photo gallery can use Colorify to colour an image wrapper, border or selected page element from each picture. Load the script and its stylesheet, mark the images and container, then configure colorify({}). The images option can also supply an array of image paths.
For a gradient, enable gradient and set gradientDirection. Reveal settings control the delay, transition duration and whether images appear in sequence; an event can trigger the reveal. These images have already loaded before Colorify hides, processes and reveals them, so this feature does not defer their download.
The browser must be allowed to read image pixels. Hosting images on the same server avoids the cross-origin restriction highlighted by the project. ISC allows commercial use and changes, provided the copyright and permission notices remain in copies.
