Abstract
Techniques are disclosed for extraction and modification of Portable Document Format (PDF) file content using Hyper Text Markup Language (HTML) based authoring tools on File Transfer Protocol (FTP) clients. A PDF FTP processor is configured to map components of stored PDF files to a hierarchical directory structure, and to receive FTP commands from a client application which identifies a PDF document and a type of access or operation (e.g., content or attribute modification, content extraction, etc.). The FTP commands also identify components of the PDF document upon which the requested operations are to be performed. The PDF FTP processor is further configured to invoke function calls to a PDF parser library to perform the requested operations. These techniques enable client software to access and manipulate the PDF document in a relatively simple and efficient manner, for example through HTML authoring tools that communicate to the server through FTP commands.
