Interactive PDF Table of Contents for Merged Document Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PDF document merging utilities lack the ability to indicate where each constituent document begins and ends, leading to inadequate navigation and user experience in combined PDF documents.
Innovation Solution
A method and system for creating a merged PDF document with an interactive table of contents, involving receiving content segments, determining page numbers, and linking them to create a navigable PDF document with a dynamic table of contents for seamless navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple PDF documents are combined using existing utilities, then the documents are merged into a single PDF file, but the ability to navigate between content segments is lost
Solution Approach 1:
The patent divides the merged PDF into distinct content segments, each with its own page range and identification markers. This segmentation allows the system to track and navigate between different original documents within the merged file, resolving the contradiction by maintaining document boundaries while enabling seamless merging.
Solution Approach 2:
The patent introduces an intermediary table of contents structure that acts as a mediator between the merged PDF and its constituent documents. This table of contents serves as a navigation aid that maps between the unified document structure and the original segmented content, enabling users to easily navigate between content segments without losing the merged document's integrity.
2Ease of operation
If a table of contents is added to indicate content segment boundaries, then navigation capability is improved, but the PDF document structure becomes more complex
Solution Approach 1:
The patent merges the table of contents functionality directly into the existing PDF document structure rather than creating a separate navigation system. By integrating TOC entries as part of the document flow and using existing PDF annotation capabilities, the system adds navigation without proportionally increasing structural complexity.
Solution Approach 2:
The patent implements a partial table of contents that only marks significant content segment boundaries rather than providing exhaustive navigation for every possible element. This selective approach provides sufficient navigation capability while minimizing the added complexity and data overhead in the PDF structure.
Data Source
AI summary
A method for creating a navigable PDF document is disclosed and involves receiving at least two content segments, each with a corresponding data structure including a title, a page count value, and a page number value. The method determines the page number value for each content segment. A set of table of contents pages is generated, populated with the titles and page numbers of the content segments. The table of contents is processed to identify title and page number positions, and pointers are established to link each title to the corresponding content segment's start location. The merged PDF document is created by combining the table of contents with the content segments, enabling users to navigate to specific portions of the document by selecting the pointers. A corresponding system is also disclosed.
