MewVG

---

MewVG is a cross-platform, fully managed .NET vector graphics library based on NanoVG.

Packages

Package	Description
Aprillz.MewVG.Core	Platform-agnostic NanoVG context and path API
Aprillz.MewVG.GL	OpenGL rendering backend (Windows, Linux)
Aprillz.MewVG.Metal	Metal rendering backend (macOS)

Highlights

• Pure C# / Fully Managed — no native dependencies required
• Cross-platform — OpenGL (Win32, X11) and Metal (macOS) backends
• NanoVG-compatible API — familiar drawing model for paths, fills, strokes, and text
• NativeAOT / Trim friendly — targets net8.0 and net10.0

Requirements

Backend	Minimum
MewVG.GL	OpenGL 3.1 / GLSL 1.40
MewVG.Metal	Metal (macOS 10.11+)

Getting Started

dotnet add package Aprillz.MewVG.Core
dotnet add package Aprillz.MewVG.GL      # for OpenGL
# or
dotnet add package Aprillz.MewVG.Metal    # for macOS Metal
