OCCSVG.NET 1.0.1-beta1

Welcome to OCCSVG.NET

OCCSVG.NET

This is a library designed for reading SVG files (Scalable Vector Graphic), accurately interpreting shapes, including their strokes, fills, and other properties. It supports most types of gradients, patterns, which gives designers the freedom to define their drawings in almost any vector drawing application and save them into SVG file.

Additionally, the OCCSVGViewer application can view and explore SVG files.

OCCSVGViewer

The application is a demo using 3D-Viewer built on Occt.NET (7.9.0). The demo is available on the GitHub, displays also the SVG model's topology and its elements in a TreeView. It allows for editing the elements in Tree, so it can be used to see how arbitrary SVG code will be displayed using the library.

The OCCSVG.NET package is built upon several key technologies: .Net, C#, C++/CLI. It also uses Occt.NET (version 7.9.0), which is based on Open CASCADE Technology (OCCT), is available from: https://www.nuget.org/packages/Occt.NET.
