de.digitalcollections.iiif.model.sharedcanvas.Canvas

public class Canvas
extends Resource

A virtual container that represents a page or view and has content resources associated with it or with parts of it.

The canvas provides a frame of reference for the layout of the content. The concept of a canvas is borrowed from standards like PDF and HTML, or applications like Photoshop and Powerpoint, where the display starts from a blank canvas and images, text and other resources are “painted” on to it.
