Skia compositor for WPE WebKit and WebKitGTK
TL;DR
A new Skia-based compositor has been successfully integrated into WPE WebKit and WebKitGTK, replacing the outdated TextureMapper. This modernization aims to simplify maintenance and enhance feature implementation.
✦ Why It Matters
Consider adopting Skia for your graphics rendering needs to simplify maintenance and improve performance.
Key Takeaways
- Explore Skia for modern graphics rendering in your projects.
- Transition from TextureMapper to reduce code maintenance.
- Utilize MotionMark for performance testing of new implementations.
- Implement filters directly with Skia to enhance performance.
Full Summary
WPE WebKit and WebKitGTK 2.54 introduced a new Skia-based compositor, replacing the older Cairo and TextureMapper systems. TextureMapper, which relied on OpenGL ES and was introduced in 2010, had become unmaintained and lacked features despite its solid performance.
The new Skia compositor streamlines the codebase, allowing for easier maintenance and feature implementation. The initial implementation utilized common elements from TextureMapper, ensuring compatibility with existing content types like video buffers and WebGL.
Performance was monitored using the MotionMark test suite, which showed no regressions. Further tests revealed that many filters could be implemented directly with Skia, improving performance over the previous method that used intermediate surfaces.
This transition not only modernizes the rendering pipeline but also sets the stage for future enhancements.
