## What it is
LunaSVG is a lightweight, portable C++ library for rendering and manipulating SVG files, built on PlutoVG. It can rasterize SVG documents to bitmaps (e.g., PNG) and supports dynamic styling via CSS stylesheets.

## Use cases
- convert svg files to png in c++
- render svg icons to bitmaps in an application
- apply css styles to an svg before rendering
- embed svg rendering in a cross-platform c++ project
- batch rasterize svg assets

## When to choose
- you need a lightweight, dependency-friendly SVG rasterizer in C/C++
- you want programmatic SVG rendering with dynamic CSS styling
- you need a simple svg2png conversion tool

## When to avoid
- you need full SVG animation or scripting support
- you need a complete HTML/CSS layout engine rather than SVG rendering
- you work in a language without C bindings

## Facets
- artifact type: library
- maturity: active
- function: image-processing, graphics, cli
- domain: graphics, image-processing, web-development, developer-tools
- platform: cpp, c, cross-platform, cli
- tags: svg-rendering, svg-to-png, plutovg, vector-graphics, css-styling
