Composite Image Data Conversion for Editable Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of editing documents in PDF format makes it inefficient and unwieldy to import and edit composite image data, as the original PDF format is not conducive to intuitive editing, leading to frustration when trying to resize, move, or perform operations on individual components of graphics.
Innovation Solution
A computer-implemented method that processes composite image data to generate an ordered stream of input operations, creating page elements for an editable document by determining the type of operations and flushing the operations buffer to convert vector and raster type operations into editable formats, allowing for efficient editing of document elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If composite image data is stored in PDF format, then document display and communication are improved, but editing complexity and operational difficulty increase
Solution Approach 1:
The patent segments the composite image data into separate vector and raster layers within the PDF structure. Vector operations are isolated in one layer while raster operations are placed in another layer, allowing independent manipulation of each type without affecting the other. This segmentation enables editors to work with vector elements (text, shapes, lines) separately from raster elements (images, backgrounds), significantly reducing editing complexity while maintaining PDF format benefits for display and communication.
2Productivity
If vector and raster operations are mixed in the same data stream, then document rendering is simplified, but editing efficiency and intuitiveness decrease
Solution Approach 1:
The patent divides the operations stream into distinct vector and raster operation sequences. Vector operations (such as path construction, text rendering, and shape drawing) are processed and stored separately from raster operations (such as image rendering and pixel manipulation). This segmentation allows editors to intuitively understand and manipulate document elements by type, improving editing efficiency and intuitiveness while the system maintains the ability to render both types together for complete document display.
3Adaptability or versatility
If PDF data is imported into an editor, then document accessibility for editing is improved, but editing flexibility and component manipulation capability remain limited
Solution Approach 1:
The patent implements layer-based segmentation that preserves the hierarchical structure of PDF documents while enabling flexible editing. Vector elements are organized in editable layers that can be independently manipulated, moved, resized, and modified without affecting raster elements. Raster elements are similarly isolated in separate layers. This approach provides editors with full flexibility to manipulate individual components intuitively while maintaining the document's overall structure and formatting.
Solution Approach 2:
The patent adds a temporal dimension to the operations stream by introducing operation timestamps and sequencing information. This allows the editor to understand the rendering order and dependency relationships between vector and raster operations, enabling flexible manipulation of document components while maintaining the correct visual output. The temporal metadata provides editors with contextual information about element relationships, enhancing editing flexibility and intuitiveness.

AI summary
Described herein is a computer implemented method for processing a set of operations including one or more vector type operations. The method includes processing the set of operations to generate one or more corresponding page elements for an editable document by: calculating an expanded bounding box for each vector type operation in the set of operations; associating each vector type operation with a subgroup, wherein a given subgroup is associated with one or more vector type operations which have collectively overlapping expanded bounding boxes; and processing each subgroup to generate a corresponding page element, wherein the page element corresponding to a given subgroup comprises drawing data based on each vector type operation associated with the given subgroup.
