We can now use one of the methods listed in the [examples of Content State encoding section](https://iiif.io/api/content-state/1.0/#63-examples-of-content-state-encoding) to generate a base64url string (**note: for brevity, we removed new line characters and white space before computing the base64url**).

We can pass the encoded value, using the `iiif-content` query parameter of the viewer landing page:

An alternative way of sharing a region of an image is to use the [Image API](https://iiif.io/api/image/3.0/#41-region). However, the context from which the region is extracted is not easily accessible. Instead, sharing a link to open the specific region with a viewer allows the users to explore another part of the image or related content and metadata in the Manifest.
