You will master:
- preparation of large images and their conversion using the CLI utility VIPS;
- building a pipeline for batch image processing on Node.js;
- displaying multiple images in one viewer and animating them;
- customizing user interactions and animated transitions using Tween.js;
- adding HTML overlays with additional information and links.
OpenSeadragon is the de facto standard for working with ultra-high-resolution images on the web. It is used by artists, libraries, museums, scientific and medical institutions around the world. It allows you to display images that are too large for the screen or even for complete transmission, providing a smooth transition from low to ultra-high quality.
The course will give you a clear understanding of the basic principles (tile pyramids, different coordinate systems) and guide you through advanced techniques that will help take your projects to the next level. You will work with real applications - from the first line of code to the final result.
The course is taught by Ian Gilman, creator and maintainer of OpenSeadragon.
About the Author: Newline (ex-Fullstack.io)
Newline (formerly Fullstack.io) is the rebrand of the technical book and course publisher founded by Nate Murray and Ari Lerner — known for the ng-book Angular series, the fullstack React books, and a long list of comprehensive reference works that anchored a generation of working developers' deep-dives into modern JavaScript framework material. The Newline name reflects the platform's evolution beyond books into a full course catalog.
The catalog covers React (including Next.js, server components, the App Router era), TypeScript, GraphQL, Node.js, Vue, the testing tracks, AWS deployment, and the broader full-stack JavaScript ecosystem. Material is taught at the level of comprehensive reference works rather than introductory tutorials — Newline courses are typically the deep-dive after the introductory tutorial.
The CourseFlix listing under this source carries 10 Newline courses spanning that range. Material is paid; Newline runs on per-course pricing or membership on the original platform.
