Glyph Weight Modification via Segmented Outline Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for modifying the visual appearance of text are labor-intensive, require multiple font files, or are limited in functionality, failing to maintain important text properties like searchability and often necessitate the generation of new font files.
Innovation Solution
A glyph modification system that receives a glyph outline and a property to modify, representing it as segments with start points, endpoints, and directions, identifies features like vertical and horizontal aspects, and modifies the outline without requiring additional font information, enabling simultaneous modification of all glyphs within a single font file without generating new files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual glyphs are modified manually to change visual appearance, then the visual appearance can be customized, but the process becomes labor intensive and searchability is lost
Solution Approach 1:
The glyph outline is segmented into multiple paths, and each path is further divided into segments with defined directions. This segmentation enables automated identification of glyph features (vertical stems, horizontal bars) and applies modifications systematically across all segments simultaneously, eliminating manual labor while preserving searchability through programmatic processing
Solution Approach 2:
The system modifies glyph visual appearance by changing parameters of the outline segments (coordinates, directions) based on identified features. By automatically adjusting segment parameters according to feature type and desired modification direction, the system achieves visual customization without manual intervention and maintains text properties
2Adaptability or versatility
If multiple master fonts are used to generate new font files for visual appearance changes, then different visual styles can be achieved, but the system complexity increases and multiple font files are required
Solution Approach 1:
The invention extracts the essential glyph outline information from font files and performs modifications directly on the segmented paths. By separating the modification process from the complete font file structure and working with extracted outline segments, the system achieves visual style changes without requiring multiple master fonts or complex interpolation mechanisms
Solution Approach 2:
The system creates modified glyphs by copying and transforming the original glyph outline segments rather than generating entirely new fonts. The segmented paths are copied, modified according to feature identification, and reassembled, enabling visual appearance changes while maintaining a single font file structure
3Adaptability or versatility
If conventional systems modify glyph outlines individually, then visual appearance can be changed, but the modification process is labor intensive and cannot be applied systematically to all glyphs
Solution Approach 1:
By segmenting glyph outlines into standardized paths with defined directions, the system enables automated feature identification and systematic modification across all glyphs in a font. This segmentation structure allows batch processing and automated application of visual changes, dramatically improving productivity while maintaining customization capability
Solution Approach 2:
The segmented path representation and feature identification system provides a universal framework that can be applied to all glyph types consistently. The same segmentation and modification processes work across different glyph categories, enabling systematic automation and high productivity while preserving the ability to customize visual appearance

AI summary
In implementations of glyph weight modification, a glyph modification system represents an outline of an unmodified glyph as segments having start points and endpoints. The segments have directions based on the start points and the endpoints such that an endpoint of a segment is a start point of another segment. The system identifies features of the unmodified glyph based on the segment directions. A property of the unmodified glyph can be modified by changing coordinates of points of the segments based on the identified features. The glyph modification system generates a modified glyph having the modified property using the points of the segments with the changed coordinates.
