Viewing Hints and Viewing Directions

viewingHint: http://iiif.io/api/presentation/2.1/#viewinghint

viewingDirection: http://iiif.io/api/presentation/2.1/#viewingdirection

Within your sequence you're going to add viewingHint and viewingDirection properties.

Values to try for viewingHint include:

• individuals
• paged
• continuous

You can also try the following values for viewingDirection:

• left-to-right
• right-to-left
• top-to-bottom
• bottom-to-top

Try different combinations of these values and review the manifest in Universal Viewer and Mirador.

Note that there are multiple other valid values for viewingHint that can be applied at different places within a manifest. Not all apply at the manifest or sequence level. We will not cover how values apply to collections or ranges.

Here's a snippet of what a portion of your sequence ought to look like:

{
  "@type": "sc:Sequence",
  "viewingHint": "individuals",
  "viewingDirection": "left-to-right",
  "canvases": [
    ...
  ]
}

See the full manifest with a viewingHint and viewingDirection

Example

Take a look at a roll-codex in the original and converted into a scroll. The manifest for the scroll uses viewingDirection and viewingHint to achieve this effect.
