fontbm is a cross-platform command-line tool for generating BMFont-compatible bitmap fonts from TrueType/OpenType fonts using FreeType2. The application parses command-line options, renders glyphs, packs them into texture atlases using MaxRectsBinPack, and outputs font metrics in multiple formats (text, XML, binary, JSON) along with PNG texture pages. The architecture is modular with clear separation of concerns: option parsing, FreeType handling, glyph packing, rendering, and output formatting. While the core logic is specific to font bitmap generation, several utility components demonstrate reusable patterns.
The LLM identified 4 files worth highlighting for reuse:
A lightweight, stream-based string builder for efficient string concatenation. Header-only, self-contained, and demonstrates a simple but effective pattern for reducing temporary string allocations in performance-sensitive code.
Extracts the file name from a path, handling both Unix and Windows separators. Isolated, depends only on standard library, and reusable in any project needing path manipulation without external dependencies.
Computes the number of digits in an integer. A pure function, header-only, and demonstrates a straightforward utility for formatting and string conversion tasks.
Splits a string by a delimiter into a vector of substrings. Well-implemented with corresponding test file, making it a safe and reusable component for string tokenization tasks.
