Computer-implemented working method, system and computer program product to create, inspect and edit the internal structure of a PDF document

摘要

The present invention relates to a computer-implemented method for creating, inspecting and editing a PDF (Portable Document Format) document, the computer-implemented method comprising the following sequential steps: creating an output object; creating a PDF writing object associated with said output object; creating a low-level (LL) document object associated with said PDF writing object; creating and opening a high-level (HL) document object associated with said low-level document object; adding a high-level document object to said high-level document object; closing said high-level document object and / or said low-level document object resulting in the delivery of said PDF document, characterized in that said low-level document object is created explicitly in a source code. Furthermore, the present invention also includes a system for performing said computer-implemented method, as well as a computer program product for performing said computer-implemented method.
