mirador-canvasnavigation

A Mirador 3 plugin which replaces the builtin canvas navigation with an extended one containing the following functionalities:

• scroll to the first canvas
• scroll to the previous canvas
• scroll to a user-selected canvas
• scroll to the next canvas
• scroll to the last canvas
• display the current canvas index and label

Installation

Currently the plugin can only be used if you build your own Mirador JavaScript bundle. To include the plugin in your Mirador installation, you need to install it from npm with npm install mirador-canvasnavigation, import it into your project and pass it to Mirador when you instantiate the viewer:

import Mirador from 'mirador/dist/es/src/index';
import canvasNavigationPlugin from 'mirador-canvasnavigation/es';

const miradorConfig = {
  // Your Mirador configuration
}
Mirador.viewer(config, [...canvasNavigationPlugin]);

Configuration

You can configure the plugin globally for all windows and/or individually for every window.

For global configuration add the canvasNavigation entry to the top-level window configuration (globally for all windows) or to the individual window object:

const miradorConfig = {
  window: {
    // ....
    canvasNavigation: {
      // Global config for all windows, see available settings below
    },
  },
  windows: [{
    // ....
    canvasNavigation: {
      // config for an individual window, see available settings below
    },
  }, // ...
}

You can view an example configuration in demo/src/index.js.

The available settings are:

• handleCanvasLabel: A function that modifies the canvas label if needed, the default implementation does not change anything. Receives this information about the current window:

  {
    canvasId: ..., // can be undefined
    canvasLabel: ...,
    currentCanvasIndex: ...,
    manifestId: ...,
  }
  

  Must return a string.

Contributing

Found a bug? The plugin is not working with your manifest? Want a new feature? Create an issue, or if you want to take a shot at fixing it yourself, make a fork, create a pull request, we're always open to contributions :-)

For larger changes/features, it's usually wise to open an issue before starting the work, so we can discuss if it's a fit.
