SkiaSharp
SkiaSharp is a cross-platform 2D graphics engine and .NET wrapper for the Skia Graphics Library. It provides a rendering API for drawing shapes, paths, and bitmaps across mobile, desktop, and server environments, functioning as both a raster graphics library and a hardware-accelerated drawing API.
The project enables the creation of custom vector drawings and dynamic UI components through precise control over strokes, fills, and mathematical transformations. It also supports programmatic image manipulation, allowing for the loading and modification of pixel arrays.
Its capabilities cover basic shape rendering, complex path definition, and graphic object transformations. Additionally, it includes systems for applying visual effects such as gradients, blurs, blend modes, and bitmap tiling.
Features
- Cross-Platform Graphics Frameworks - Provides a high-performance 2D drawing system for creating hardware-accelerated visuals and animations across .NET desktop, mobile, and server platforms.
- Coordinate-Based Drawing APIs - Provides a low-level interface for performing high-performance 2D drawing operations by specifying absolute or relative pixel coordinates.
- GPU Hardware Acceleration - Routes drawing commands through native libraries to GPU-backed contexts for high-performance hardware-accelerated screen rendering.
- Bitmap Manipulation - Provides systems for loading, saving, and programmatically modifying pixel arrays to create and animate raster images.
- Shape Rendering - Renders geometric primitives such as circles, ovals, and rectangles using precise coordinates and color specifications.
- 2D Rendering Engines - Functions as a rendering engine optimized for drawing 2D shapes, paths, and bitmaps using hardware acceleration.
- .NET Image Processing Libraries - Brings the Skia Graphics Library to the .NET ecosystem as a high-performance image processing and rendering library.
- Raster Graphics Libraries - Provides a comprehensive library for managing pixel arrays and rasterizing complex vector graphics into images.
- Vector Drawing APIs - Provides precise programmatic control over strokes, fills, and mathematical transformations for creating complex vector paths.
- Vector Path Construction - Enables the definition of complex geometric paths using sequences of connected lines and curves with custom strokes and fills.
- C Function Bindings - Implements a P/Invoke layer that maps .NET method calls to native Skia C++ functions via platform-specific pointers.
- Cross-Platform Abstractions - Provides a unified .NET interface that abstracts rendering commands across different operating systems through a shared native library.
- Programmatic Manipulation Libraries - Offers a programmatic library for loading and modifying bitmaps and pixel arrays to apply filters and visual effects.
- Canvas State Management - Maintains a stack of drawing states, including transformations and clipping regions, to isolate and manage sequential paint operations.
