摘要
Techniques are disclosed for extraction and modification of Portable Document Format (PDF) file content using Hyper Text Transfer Protocol (HTTP) requests. A PDF web server is configured to receive HTTP requests from a client which identify a PDF document and a type of access or operation (e.g., content or attribute modification, content extraction, etc.). The HTTP requests include Uniform Resource Locator (URL) path to identify components of the identified PDF document upon which the requested operations are to be performed. The PDF web server is further configured to invoke function calls to a PDF parser library to perform the requested operations. These techniques eliminate the need for client software to include relatively complex PDF parser libraries, instead allowing the client to access and manipulate the PDF document in a simpler and more efficient manner. In some cases, the PDF web server may be incorporated in a PDF viewer.
