svg2ttf

Converts SVG fonts to TTF format. Originally written for Fontello, this tool can be useful for various font conversion projects.

@lulliecat/svg2ttf is a security-updated fork of the original svg2ttf. The development environment has been modernized, and TypeScript type definitions will be provided in future releases.

For Developers

The internal API is similar to FontForge's API. Since the primary goal is generating icon fonts, some specific TTF/OTF features (such as kerning) may not be fully supported. However, the current codebase provides a solid foundation for development, saving you significant time in implementing correct TTF table writing and optimization.

Installation

Install globally via npm:

npm install -g @lulliecat/svg2ttf

CLI Usage

Convert an SVG font to TTF format:

svg2ttf fontello.svg fontello.ttf

API

svg2ttf(svgFontString, options) -> buf

Parameters:

• svgFontString (string) - SVG font content as a string
• options (object) - Configuration options
  • copyright (string, optional) - Copyright text
  • description (string, optional) - Font description
  • ts (number, optional) - Unix timestamp in seconds to override creation time
  • url (string, optional) - Manufacturer URL
  • version (string, optional) - Font version string (e.g., Version x.y or x.y)

Returns:

• buf - Internal byte buffer object, similar to DataView. The buffer property contains a Uint8Array or Array with the TTF content.

Example:

const fs = require('fs');
const svg2ttf = require('@lulliecat/svg2ttf');

const ttf = svg2ttf(fs.readFileSync('myfont.svg', 'utf8'), {});
fs.writeFileSync('myfont.ttf', Buffer.from(ttf.buffer));
