METHOD AND SYSTEM FOR SUPPRESSION OF FEATURES IN PAGES OF CONTENT

摘要

Suppression of one or more features in an image of a page of content may be achieved by acquiring a page image, identifying one or more features in the page image that are to be suppressed or not to be suppressed, and preparing a substitute page image which only includes images of the features that are not to be suppressed. Preparing a substitute page image may include generating a blank image and using location and size information to copy images of the non-suppressed features from the original page image to the blank image. In other embodiments, preparing a substitute page image may include removing image information from the original page image outside the non-suppressed features, or identifying and removing features that are to be suppressed from the original page image. Feature suppression may be used to implement access rules that limit the content in a page image. Aspects of the invention may also be employed on pages of content in non-image files.
