Cairo is a software library used to provide a vector graphics-based, device-independent API for software developers. It is designed to provide primitives for 2-dimensional drawing across a number of different backends.
Anti-Grain Geometry (AGG) is a high-quality 2D rendering library written in C++. It features anti-aliasing and sub-pixel resolution. It is not a graphics library, per se, but rather something to build a graphics library upon.This app doesn't have any features at the moment.
The drawing engine supports rendering vector graphics (such as lines, curves, and figures) and text (in a variety of fonts, sizes, and styles) onto raster images in all commonly used graphics file formats. Can be used in web, mobile, desktop, cloud and IoT scenarios.
