ttf2lff Technical Report utility is a command-line tool primarily used within the ecosystem. Its purpose is to convert TrueType Fonts (.ttf) LibreCAD Font Format (.lff)
, allowing users to use custom system fonts within CAD projects. 1. Tool Overview Core Function
: Extracts font glyphs from TTF files and converts them into vector-based stroke data. Library Dependency : Relies heavily on the FreeType library for rendering and glyph extraction. Output Format : Generates
files, which are plain text files representing single-stroke vector fonts suitable for CAD polylines. 2. Usage and Commands ttf2lff
The tool is typically invoked via the terminal or command prompt. Typical Command Syntax Linux/macOS ttf2lff InputFont.ttf OutputFont.lff ttf2lff.exe InputFont.ttf OutputFont.lff Installation Note : While it is part of the LibreCAD source build
, it is often not included in the standard pre-compiled binary packages. Users may need to compile it manually or use the Experimental Online Converter 3. Operational Workflow Preparation : Locate your desired file (e.g., Conversion : Run the command to produce the counterpart. Deployment : Move the resulting file into the LibreCAD font directory (usually /usr/share/librecad/fonts on Linux or the subfolder in the installation directory on Windows). Verification
: Restart LibreCAD and select the new font from the text tool list. 4. Known Limitations & Troubleshooting Outline vs. Solid : LibreCAD primarily supports outline fonts
. Converted fonts may appear as hollow outlines. To achieve a "solid" look, users must manually apply a to exploded text or increase the layer line width Platform Compatibility : There are documented issues with older x86 builds of running on newer ARM-based macOS (M1/M2) hardware due to library linking errors. Font Matching The most critical aspect of ttf2lff —and the
: Some converted fonts may default to the "ISO" style if the conversion process fails to correctly map the glyphs into a format LibreCAD recognizes.

ttf2lff is a command-line utility that converts TrueType font files (.ttf) into the LFF (LibreFont Format) or another lightweight vector-font representation used by some niche projects and embedded systems. It’s typically used when a project needs a compact outline format or simpler glyph data than full OpenType/TrueType provides. ttf2lff is a command-line utility that converts TrueType
The utility is operated via the command line. Standard syntax is as follows:
ttf2lff [options] <input_font.ttf> [output_font.lff]
Common Parameters:
Operational Example:
To convert the standard Arial font for use in LibreCAD:
ttf2lff Arial.ttf Arial.lff
