Overview
I created digital archive tools centered on IIIF. You can try them at the following URL.
https://nakamura196.github.io/viewer/
Currently, two features are provided:
- Image comparison using Mirador 3
- Canvas number specification tool
Image Comparison Using Mirador 3
https://nakamura196.github.io/viewer/input
Specify the URLs of the manifest files or Canvas URIs you want to compare. Please try the examples provided.

You can compare images as shown below.

Canvas Number Specification Tool
https://nakamura196.github.io/viewer/canvas
In IIIF-compatible viewers, canvas numbers are often specified in the format {url}?manifest={manifest}&canvas={canvas}.
However, since it can be difficult to obtain the canvas URI, I created a tool that automatically retrieves the canvas URI by specifying the manifest file and canvas number.
Enter the required items and click the “Create URL” button to display a URL containing the canvas URI. It may be hard to understand at first, so please try the “Examples” at the bottom of the screen.

Summary
This only supports IIIF Presentation API v2, but I hope it proves useful.
