Is it possible to limit the view of a window to a single canvas from a manifest?
For instance, I would like to show only one or a few pages from this book and not let users get lost in the 127 pages.
One possible option would be to remove altogether the navigation buttons, but I can't find an option to remove them, and display:none; in the css is not having any effect.
It's fairly straightforward with a custom request post-processor that just removes the items you don't want to display from the manifest before it's received and stored by Mirador.
mirador.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Mirador</title>
<script src="https://cdn.jsdelivr.net/npm/mirador@3.3.0/dist/mirador.min.js"></script>
</head>
<body>
<div id="mirador"></div>
<script type="text/javascript">
const filterManifestItems = (url, action) => {
if (action.type === 'mirador/RECEIVE_MANIFEST') {
const pagesQuery = new URLSearchParams(window.location.search).get('pages')
if (pagesQuery) {
const pages = pagesQuery.split(',').map((page) => new Number(page))
action.manifestJson.items = pages.map((page) => action.manifestJson.items[page - 1])
}
}
}
Mirador.viewer({
id: 'mirador',
windows: [
{
manifestId: 'https://sites.dlib.nyu.edu/viewer/api/presentation/books/isaw_plond000002/manifest.json'
}
],
window: {
defaultView: 'single',
views: [
{ key: 'single', behaviors: ['individuals'] }
],
},
requests: {
postprocessors: [filterManifestItems]
}
})
</script>
</body>
</html>
If you save that as an HTML file, then open it in a browser, you will see all of the pages rendered in Mirador. If you then edit the URL in the browser address bar and add, for example ?pages=1,10,100, then you will only see pages 1, 10 & 100.
