Struct SkiaWGPURenderer 

pub struct SkiaWGPURenderer { /* private fields */ }

Available on crate feature unstable-wgpu-28 and (crate features renderer-skia or renderer-skia-opengl or renderer-skia-vulkan) only.

Use the Skia renderer with WGPU when implementing a custom Slint platform where you want the scene to be rendered into a WGPU texture. The rendering is done using the Skia library with platform-native GPU acceleration.

This is the Skia equivalent of FemtoVGWGPURenderer, offering superior font rendering quality through platform-native text rasterizers.

Rendering notifier callbacks registered via Window::set_rendering_notifier() will receive GraphicsAPI::WGPU28 with the renderer’s instance, device, and queue.

Implementations

impl SkiaWGPURenderer

pub fn new( instance: Instance, adapter: Adapter, device: Device, queue: Queue, ) -> Result<SkiaWGPURenderer, PlatformError>

Creates a new SkiaWGPURenderer.

The instance, adapter, device and queue are the WGPU resources used for rendering. The adapter is needed to determine the GPU backend and create the Skia graphics context.

The wgpu resources are also provided to rendering notifier callbacks via GraphicsAPI::WGPU28.

pub fn render_to_texture(&self, texture: &Texture) -> Result<(), PlatformError>

Render the scene to the given texture.

The texture must have been created with RENDER_ATTACHMENT usage and have a supported format. Supported formats depend on the GPU backend: Rgba8Unorm and Rgba8UnormSrgb are supported on all backends; Bgra8Unorm is additionally supported on Metal and Vulkan.
