3.4.814M downloads/mosvg-net/SVG ↗New releases in your daily digest, changelog included.

Public fork of the C# SVG rendering library on codeplex. This started out as a minor modification to enable the writing of proper SVG strings. But now after almost two years we have so many fixes and improvements that we decided to share our current codebase to the public in order to improve it even further. So please feel free to fork it and open pull requests for any fix, improvement or feature you add. License: Microsoft Public License.

Additional notes

Changes

Added: A class, SvgOptions, with external css parameters for styling or transforming the SvgDocument.
Added: Support for .NET 4.7.2, .NET 4.8.1 and .NET 8.0.
[Breaking Change] The support for .NET 8 resulted in a breaking change to the signature of methods in CoordinateParser.

- The use of read-only arguments as referenced variable is not necessary.
- The use of ref in the function arguments resulting in CS8352 error are all removed.

Fixes

Fixed: XML namespace prefixes are also applied for nodes declaring them (see PR #1106).
Fixed: Parameter is not valid (see PR #1131).

Infrastructure

Split tests SVG/PNG files into Issues and W3C Test Suite. W3C Test Suite files are not automatically downloaded.
