SVG++ library can be thought of as a framework, containing parsers for various SVG syntaxes, adapters that simplify handling of parsed data and a lot of other utilities and helpers for the most common tasks. Take a look at Tutorial to get the idea about what it is.

• Is a header-only library

• Can be used with any XML parser

• Compile time configured - no virtual functions

• Minimal runtime overhead - you pay only for what you get

• Has wide range of possible uses:

  • Fully functional, conforming SVG viewers
  • Simple in-app SVG rasterizers
  • Import modules of vector editing software
  • Implementing path-only input of SVG format with minimal efforts in any graphics or math software

• Requires only Boost library itself (demo, tests and sample have their own requirements)

• Compatible with C++03, but requires conforming implementation, due to heavy usage of templates

• Supports any character type (char and wchar_t). Other (Unicode from C++11) were not tested, but should be ok.

• Path data - parsing, simplification
• Transform list - parsing, simplification
• Color, including ICC color - parsing
• Lengths - highly configurable handling of SVG lengths, full support of all SVG length units
• Basic shapes - optional conversion to path
• Style attribute - parsing, taking in account differences in parsing presentation attributes and style properties
• Automatic marker positions calculation
• Viewport and viewbox handling

• An SVG viewer or library that produces raster image from SVG (though C++ demo app included, which renders SVG with AGG, GDI+ or Skia graphics library)
• Renders anything itself

• SVG++ update 1.2.1 fixes handling text content inside <a> element that is a child of <text> element.
• SVG++ update 1.2 focuses on reducing compiler memory usage by allowing separation of template heavy Boost.Spirit code to other compilation unit.

• CSS Processor. Processing CSS is outside of SVG++ scope, but it'll be nice to have some generic implementation of CSS selectors to use at preprocessing stage.
• SVG Filter Effects. Some filters are already implemented in demo application but the complete solution requires more efforts. Generic enough parts may fit in SVG++ source base. Usage of Boost.GIL may make the code more reusable.
• Animation. Implementation of animation in the demo application. Probably some utilities may get to SVG++.
• Try to reduce compiler memory usage by switching to some C++11 metaprogramming library (brigand?). Evaluate upgrade to Boost.Spirit 3.0.
• Extend demo with Cairo support?
• More wrappers for XML parsers?
• Evolve demo to fully functional SVG rendering component for one of the graphic engines. A major gap in demo's SVG implementation is text and font support. It'll be too complex to make it cross-engine, but for the single engine chosen and probably with third-party libraries like FreeType it's pretty feasible.
