Document Conversion Layering for Web Format Fidelity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for converting electronic documents from word processing programs into web-compatible formats result in low output speed and visual format discrepancies between the original and converted documents.
Innovation Solution
A method and system that load a document file, extract content and layout information, generate a content layer and a frame layer, and insert intermediate blank spaces to maintain page separation, ensuring the converted document resembles the original in visual format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an electronic document is converted into a web-compatible format using conventional methods, then the document can be viewed through a web browser, but the output speed is low and visual format differences occur
Solution Approach 1:
The patent divides the document conversion process into two independent layers: a content layer containing all document content elements and a frame layer containing page frame information. This segmentation allows parallel processing of content extraction and layout reconstruction, significantly improving conversion speed while maintaining visual fidelity through coordinated layer composition
Solution Approach 2:
The patent transitions from a single-page sequential processing model to a multi-layer parallel processing model by introducing the concept of overlaying content layers onto frame layers. This dimensional change from 2D page representation to 3D layered structure enables simultaneous processing of multiple document elements, achieving high-speed conversion without sacrificing visual accuracy
2Adaptability or versatility
If the original document is converted into a format solely provided by the web browser, then web compatibility is achieved, but visual format differences occur between the converted and original documents
Solution Approach 1:
The patent introduces frame layers as an intermediary structure that carries page frame information from the original document. This frame layer acts as a mediator between the source document layout and the web browser's native format, preserving visual formatting characteristics while enabling web compatibility through the overlay mechanism
3Adaptability or versatility
If conventional conversion methods are used, then web compatibility is achieved, but the output speed is low
Solution Approach 1:
The patent segments the conversion process into independent content extraction and frame generation operations that can proceed in parallel. The content layer extracts all document elements while the frame layer processes page layout information simultaneously, then combines them through overlay, achieving high-speed conversion while maintaining web compatibility
Solution Approach 2:
The patent performs preliminary actions by pre-generating the frame layer with all page frame information before final composition. This allows the content layer to be overlaid onto the prepared frame structure without additional processing delays, significantly improving output speed while ensuring web-compatible format generation

AI summary
Provided are a method of converting a document and a system for performing the method. The method includes loading a document file about an original document generated to have a plurality of pages, extracting content information about content of the original document and layout information about a page layout of the original document, generating a content layer composed of a single sheet including content corresponding to the content of the original document, inserting an intermediate blank space into a separating position corresponding to a page boundary of the original document on the single sheet of the content layer, generating a frame layer composed of a single sheet including as many page frames, and generating a converted document composed of a single sheet in which the content layer and the frame layer overlap and visually providing a page separation substantially the same as a page separation of the original document.
