Zoomify

Posted on by



dezoomify-rs is a tiled image downloader.Some webpages present high-resolution zoomable images without a way to download them.These images are often tiled: the original large image has been split into smaller individual image files called tiles.The only way to download such an image is to download all the tiles separately and then stitch them together.This process can be automated by a tiled image downloader.

The most common tiled image downloader is probably dezoomify,an online tool which is very easy to use.

The goal of this project is not to replace the traditional dezoomify.However, some images are so large that they can’t be efficiently downloaded and displayed inside a web browser.Other times, a website tries to protect its tiles by refusing access to them when certain HTTP headers are not set to the right values.dezoomify-rs is a desktop application for Windows, MacOs and linux that does not have the same limitations as the online zoomify.dezoomify-rs also lets the user choose betweenseveral image formats,whereas in dezoomify, you can only save the image as PNG.

dezoomify-rs supports several zoomable image formats, each backed by a dedicated dezoomer.The following dezoomers are currently available:

  • Zoomify allows you to deliver high-resolution images over the Web - it's fast & easy! Zoomify's products include Zoomify HTML5, Zoomify Flash, and Zoomify Enterprise.
  • Zoomify Free Converter is a lightweight piece of software designed to help you convert your images so that they can be panned and zoomed fast and hence, become suitable for uploading on your website.
  • Google Arts & Culture supports downloading images from artsandculture.google.com;
  • zoomify supports the popular zoomable image format Zoomify.
  • deepzoom supports Microsoft’s DZI format (Deep Zoom Image), that is often used with the seadragon viewer.
  • IIIF supports the widely used International Image Interoperability Framework format.
  • Zoomify PFF supports the old zoomify single-file image format.
  • Krpano supports the krpano panorama viewer
  • IIPImage supports the iipimage image format
  • NYPLImage supports the nypl image format
  • generic For when the tile URLs follow a simple pattern.
  • custom for advanced users.It allows you to specify a custom tile URL format that can contain multiple variables. This gives you the most flexibity, but requires some manual work.

Internet Imaging Protocol (IIP) with JTL extension is also handled. Zoomify allows you to deliver high-resolution images over the Web - it's fast and easy!

Usage instructions

Download dezoomify-rs

First of all, you have to download the application.

  1. Go to the the latest release page,
  2. download the version that matches your operating system (Windows, MacOS, or Linux),
  3. Extract the binary from the compressed file.

On some operating systems, you may have to authorize the application executionbefore being able to launch it. See how to doin MacOS.

Supported output image formats

Dezoomify-rs supports multiple output image formats.The format to use is determined by the name of the output file.For instance, entering dezoomify-rs http://example.com/ my_image.png on the command linewill create a PNG image.

Each image format encoder has a distinct set of features and limitations :

  • PNG images are compressed losslessly, which means that the output image qualityis (very slightly) better than JPEG, at the expense of much larger file sizes. The PNG encoder in dezoomify-rs can create very large images;it is not limited by the available memory on your computer.This format is chosen by default when the image is very large,or its size is not known in advance.
  • JPEG is the most common image format. JPEG images cannot be more than 65,535 pixels wide or high. This format is chosen be default for images that fit within this limit. The JPEG encoder in dezoomify-rs requires the whole image to fit in memory on your computer.
  • All formats supported by image-rsare also supported.
  • IIIF, which allows you to re-create a zoomable image locally.This is the recommended output format when your image is very large(multiple hundreds of megapixels), since most image viewers do not accept huge PNGs or JPEGs.If the output path ends with .iiif, a folder will be created instead of a single file,with its structure following the IIIF specification.A file called viewer.html will be created inside this folder,which you can open in your browser to view the image.
