## What it is
Blend2D is a high-performance 2D vector graphics engine written in C++ that uses a built-in JIT compiler (via AsmJit) to generate optimized rendering pipelines at runtime. It provides an analytic rasterizer, text rendering, image codecs, and multithreaded rendering with zero dependencies besides AsmJit.

## Use cases
- render 2D vector graphics with high performance
- rasterize shapes and bezier curves to bitmaps
- render text with TrueType and OpenType fonts
- load and save images in PNG, JPEG, BMP, and QOI formats
- accelerate 2D rendering across multiple threads
- generate SIMD-optimized rendering pipelines at runtime
- embed a self-contained 2D renderer in a C++ application

## When to avoid
- you need GPU-accelerated rendering rather than software rendering
- you need a high-level UI toolkit or scene graph on top of the renderer
- your project is not C/C++ or lacks CMake build integration

## Facets
- artifact type: library
- maturity: active
- function: graphics, image-processing, nlp
- domain: graphics, desktop-applications, cross-platform
- platform: cpp, cross-platform, windows
