What Hacker News says

3 sources
I maintain a suite of opensource tools that do exactly that: download zoomable image tiles and stitch them together. - dezoomify (https://dezoomify.ophir.dev) is a web application. It is super easy to use, but the final size of the image is limited by the browser. No browser can create gigapixel canvases. - dezoomify-rs (https://lovasoa.github.io/dezoomify-rs/) is a command-line desktop application for Linux, MacOS, and Windows that does the same thing. It has no limitation (other than the one imposed by the file formats themselves) on the final image size. - dezoomify-extension (https://lovasoa.github.io/dezoomify-extension/) is a browser extension to extract zoomable image URLs from webpages. It is less relevant for google arts and culture, where the zoomable image URL is the URL of the viewer page itself. If someone is interested by ho

w the zoomable image format used by google arts works, the source code of dezoomify-rs is quite understandable: https://github.com/lovasoa/dezoomify-rs/tree/master/src/goog... In the case of this image, I'm not sure the highest zoom level saved as a single PNG makes a lot of sense. No image viewer will accept to open a PNG file of this size. For JPEG, the format does not even allow images of that size.

For those who would be interested in downloading the picture, or other images using the same technology, I maintain a set of opensource zoomable image downloaders : - dezoomify : https://github.com/lovasoa/dezoomify (a browser-based tool that recreates the image as an HTML5 canvas. Limited by the maximal size of canvases in browsers) - dezoomify-rs : https://github.com/lovasoa/dezoomify-rs (a command-line utility that can download larger images, including the one presented in this post) - dezoomify-extension: https://github.com/lovasoa/dezoomify-extension/ (a browser extension that finds zoomable images in web pages and allows downloading them with dezoomify) If you are passionate about high-resolution art and know javascript or rust, you can come contribute !
