Canvas2Svg translates drawing commands from an HTML5 Canvas into SVG format using JavaScript. The library enables users to capture canvas content as SVG documents, facilitating persistence, export, and integration with SVG-based workflows. It achieves this by creating a mock 2D canvas context and building a scene graph in SVG as drawing operations are performed.
Canvas2Svg offers a clean and simple API for converting canvas content to SVG. Its focus is on providing a direct mapping of canvas drawing operations to SVG elements, resulting in predictable and reliable results. The library also provides support for various drawing primitives and features, making it suitable for a range of canvas-based applications.
- Core Functionality: Converts Canvas 2D drawing commands (fillRect, strokeRect, moveTo, lineTo, etc.) to SVG elements.
- Node.js Support: Can be integrated with Node.js using jsdom and node-canvas for server-side SVG generation.
- Flexible Context: Works seamlessly with standard HTML5 Canvas 2D contexts.
- Example Cases: Includes examples and test cases for various drawing scenarios, including text and gradients.
- Easy Integration: Straightforward API for converting canvas drawings to SVG.
- Test Harness: Provides a built-in test harness for verifying the correctness of SVG conversion.
- RGBA Support: Supports RGBA values for fill and stroke colors.
The project is actively maintained with regular updates addressing bugs, adding features, and improving stability. It has a consistent release history and a growing community contributed to bug fixes and test cases. The documentation is reasonably complete, covering core functionalities and usage examples.
Canvas2Svg is valuable for developers needing to persist or export canvas content as SVG, providing an alternative to manual conversion or custom format solutions. It benefits designers, developers building interactive visualizations, and anyone needing scalable vector graphics from canvas-based applications.
