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.

Abstract

The present invention relates to low-resolution placeholder content for file navigation. A system structure generates the low-resolution placeholder content. The content keeps usefulness of the application response through keeping and displaying the structure of the content, thus promoting reduction of memory request which is related with whole and unchangeable content of a pre-rendered structure. The system structure allows storage of pre-rendered content through a scaling level which is lower than the scaling level that is used for actual display, pre-rendering the content with a lower scaling level for allowing application of adjustment with lower scaling level for providing a structure integrity which is higher than that of the data that are obtained according to full-display scaling level rendering and compression. The pre-rendered content is extended to a scaling level for displaying for obtaining a low-resolution appearance which is directly fused with the full-resolution content. Furthermore when the full resolution content is available, the pre-rendered content is transited between the low-resolution content and the full-resolution content.

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...
