System and method for Rendering Document in Web Browser or Mobile Device regardless of Third-Party Plug-In software

摘要

Rendering of documents that are in proprietary formats in a browser or mobile device, by converting a plurality of resources in a document file into a plurality of files that are native to a browser. A style sheet is based on the document file, wherein an aggregate of the plurality of files together with the style sheet are configured to cause the browser to render an appearance of the document file. Based on the document file, an invisible layer is generated to be laid on the appearance, wherein the invisible layer enables actions to be performed on the document file. This allows the viewing and accessing documents regardless of whether a software or plug-in there for is installed. Pages from the document file may be streamed as they are processed. The font may be extracted from the file for use in the action layer, images may be down sampled if the image size is large, graphics may be mapped to an equivalent scalable vector graphic operation. The third party software application may provide document files via an application programming interface, with the browser rendering the file regardless of chester a plug-in that supports the document file is installed on the device, allowing text seletion, copying, cutting, pasting, searching, filling or hyperlinking in a pdf, doc, ppt or xls file in a cloud environment.
