Struct FramebufferRenderTarget 

pub struct FramebufferRenderTarget { /* private fields */ }

Skia render target that renders to a framebuffer surface. No GPU acceleration available.

Implementations

impl FramebufferRenderTarget

pub fn new( platform_surface: &dyn IFramebufferPlatformSurface, use_scaled_drawing: bool, ) -> Self

Creates a framebuffer render target for a framebuffer surface.

pub fn from_render_target( render_target: Rc<dyn IFramebufferRenderTarget>, use_scaled_drawing: bool, ) -> Self

Creates a framebuffer render target over the render target of a framebuffer surface.

pub fn with_text_rendering(self, text_rendering: TextRenderingSource) -> Self

The render target reading the text rendering parameters of the platform from text_rendering every frame (the default: none, so greyscale text; docs/porting/text-rendering.md).

Trait Implementations

impl IRenderTarget for FramebufferRenderTarget

fn properties(&self) -> RenderTargetProperties

The properties of this render target.

fn create_drawing_context( &self, scene_info: &RenderTargetSceneInfo, ) -> (Box<dyn IDrawingContextImpl>, RenderTargetDrawingContextProperties)

Creates a drawing context for a rendering session.

fn platform_render_target_state(&self) -> PlatformRenderTargetState

The readiness of the underlying platform target.

fn dispose(&self)

Releases the render target.

fn try_create_drawing_context( &self, scene_info: &RenderTargetSceneInfo, ) -> Result<(Box<dyn IDrawingContextImpl>, RenderTargetDrawingContextProperties), RenderTargetError>

Creates a drawing context for a rendering session, or says that the target is not ready or is corrupted: what the reference reports by throwing RenderTargetNotReadyException or RenderTargetCorruptedException out of CreateDrawingContext. The compositor calls this member. A target that cannot report either keeps the default.
