Lua scriptable SVG image generator

lsvg is a Lua interpreter specialized to generate SVG images.

It is based on LuaX and uses a pure Lua library to generate SVG images. It optionally requires ImageMagick to make PNG, JPEG or PDF images.

lsvg was initially inspired by svg-lua.

Releases

It is strongly recommended to build Lsvg from source, as this is the only reliable way to install the exact version you need.

However, if you do require precompiled binaries, this page offers a selection for various platforms: https://cdelord.fr/pub.

Installation

lsvg is available on Codeberg: https://codeberg.org/cdsoft/lsvg.

lsvg uses LuaX and Bang.
