niji

Generic 2D graphics library for C++14.

Introduction

Niji is a generic library for 2D graphical path manipulation, it provides containers, generators (graphics), adaptors (views) and algorithms for path, in a sense like STL/Boost.Range.

On the other hand, niji doesn't have the ability to render these paths on its own, you can think it as a generic front-end for arbitrary graphic engines which can do the real rendering.

Overview

Niji can be divided into these submodules:

• core - path fundamentals.
• container - various path containers, e.g. path, group, etc.
• graphic - common graphics, e.g. ellipse, round_rect, etc.
• geometry - adapted geometry path for Boost.Geometry.
• view - various path adaptors, e.g. inverse, transform, stroke, etc.
• make - convenient path makers.
• algorithm - path algorithms, e.g. bounds, length, etc.
• support - traits, basic geometries, math...
• sink - predefined backends, e.g. Skia, Direct2D, etc.

Quick Example

The following example shows how to output the path of a dashed ellipse:

using namespace niji;                                                 
                                                                             
render(ellipse<double>({100, 100}, 50) | views::dash<double>({6, 2}), sink);

• all components reside in namespace niji.
• render(path, sink) sends the path commands to sink.
• ellipse<T> is a predefined path generator.
• views::dash<T>(pattern) returns a path adaptor that generates dash lines.
• sink is something that handles the path commands.
