LOW RESOLUTION PLACEHOLDER CONTENT FOR DOCUMENT NAVIGATION

摘要

Architecture generates low resolution placeholder content that preserves the usefulness of application responsiveness by preserving and displaying the structure of the content. This facilitates decreased memory requirements associated with pre-rendering structurally-intact content. The architecture enables the storing of pre-rendered content at a lower zoom level than is intended for actual display to require fewer resources, pre-rendering content at a lower zoom level to allow the application to adjust for the lower zoom level to provide more structural integrity than would be achieved rendering at full display zoom level and compressing the resulting data, stretching the pre-rendered content to the zoom level that is intended for display in order to achieve a low resolution appearance that merges directly with the full resolution content, and transitioning between low resolution content and full resolution content when the full resolution content becomes available.
