Jim's TrueType QR Code Font Generates QR Codes from Text

Overview of Jim's QR Code Font

Jim's newly developed TrueType QR Code font allows users to encapsulate text in brackets to generate QR codes. For example, typing 'abc[hello]ghi' renders as normal text with a QR code for 'hello' embedded within. This innovation combines functionality with legibility, making it practical for various applications.

Font Variants and Technical Details

The project includes three font downloads: qrfont-1L, qrfont-2L, and qrfont-3L, supporting character limits from 17 to 53 characters based on their module size. The fonts are constructed using a build script that generates glyph outlines and applies OpenType GSUB features, critical for rendering the QR codes correctly.

User Instructions and Features

Users can build the fonts using the provided scripts and use a compatible TrueType font as a base, with Liberation Sans Regular being the default. Commands are included for both layout-only builds and full-parity versions, providing flexibility based on user needs. The interactive web demo allows immediate testing of the font's capabilities.

Licensing and Availability

This QR code font project is licensed under the SIL Open Font License, Version 1.1. It is categorized as a proof-of-concept and requires an environment capable of handling OpenType features for optimal performance. The generated files and demo can be accessed through the project's repository.
