Extraction of text and graphics from PDF files for use in browser files such as HTML files with defined anchorable information units or hyperlinks by direct text and graphic extraction rather than use of scanning based approaches

摘要

System for processing multimedia files for presenting information for use in browser suitable multimedia data files. System comprises a content parser for identifying text and graphics within a file, an image processor for processing and identifying graphics content to identify embedded test, a text sorter for parsing the identified text and embedded text to find text elements according to preset sorting rules and a memory for storing browser files containing text elements. Independent claims are made for a method for producing anchorable information units (AUI) from PDF format documents by extracting text segments from PDF documents, determination of segment context, with context chose from a hierarchical structure and definition of text segments as AUIs and a machine readable program storage device containing a program for extracting text etc. from PDF files.
