However, the additional resource requirements of keeping pre-rendered content in memory limits the extent to which content can be pre-rendered, thus limiting the effectiveness of this approach

Embodiment Construction

[0016] The disclosed architecture generates placeholder content for full resolution content in order to maintain the usefulness of application responsiveness by maintaining and displaying the structure of the content. This facilitates reducing the memory requirements associated with pre-rendering structurally intact content and allowing storage and caching of pre-rendered content at lower zoom levels than intended for actual display, requiring fewer resources. The architecture transitions from low-resolution placeholder content to full-resolution content on document pages (whether viewed or not) when full-resolution content becomes available. Note that the term "document" is intended to mean any type of application file containing data, such as media in the form of text, images, video, etc., and does not refer specifically to word processing documents. For example, a document may be a spreadsheet of a spreadsheet application.

[0017] Reference will now be made to the drawing...

Abstract

The present invention relates to low resolution placeholder content for document navigation. The architecture generates low-resolution placeholder content that keeps the app responsive and useful by maintaining and displaying the structure of the content. This facilitates reducing the memory requirements associated with pre-rendering structurally intact content. This architecture allows storing pre-rendered content at lower zoom levels than intended for actual display to require fewer resources, and pre-rendering content at lower zoom levels to allow applications to adjust for lower zoom levels to provide Higher than the structural integrity that would be achieved by data rendered and compressed at full display zoom, pre-rendered content is stretched to the zoom level intended for display in order to achieve a low-resolution look that blends directly with full-resolution content , and transition between low-resolution and full-resolution content when full-resolution content becomes available.

Description

technical field [0001] The present invention relates to document content display. Background technique [0002] The responsiveness of an application during document navigation is generally limited to how quickly the application can render content to keep up with the user's navigation. Responsiveness then tends to scale based on document complexity and performance characteristics of the machine hardware. [0003] Some products attempt to address responsiveness by allowing users to continue navigating a document while content rendering lags behind. While the app is catching up, the product displays blank content or a checkerboard-style pattern to indicate that the content is not ready. The downside of this solution is that it greatly reduces the usefulness of the responsiveness achieved, since the user cannot see the content while navigating. [0004] Other products address responsiveness by pre-rendering additional content that is not yet on screen to reduce the likelihood...
