Abstract
An image can be presented using render-tiles, which are movable rendering contexts in which multiple image-tiles can be drawn as a single image. To optimize performance, the render-tiles can be large enough to minimize the number of render-tiles necessary to present the image within the screen view of a client device, while remaining small enough to avoid memory or performance issues when panning or zooming the image. A set of active image-tiles and active render-tiles can be identified based on a specified view boundary that represents a portion of the image that is presented by a client device. The active render-tiles can be presented by the client device and the image-tiles can be drawn into the render-tiles to present the image. The render-tiles can be generated as needed and inactive render-tiles can be stored for later use or recycled.
