Abstract
When a document generated from an application is printed, each page of the document is treated as a separate image Then, one or more templates are generated for a document, with each template containing common elements for a set of images in the document. For each set of images, sets of changes are identified. The templates and corresponding sets of changes to each image in a set of images may be reduced from one color space to another color space. The reduced templates and corresponding sets of changes are then compressed and formatted into a native file transfer format understood by a mobile computing tool, for transfer to a mobile computing tool, where the data is decompressed and images are rebuilt from the templates and corresponding sets of changes.
