Struct SoftwareBackend 

pub struct SoftwareBackend { /* private fields */ }

Software rendering backend using tiny-skia

Implementations

impl SoftwareBackend

pub fn new(context: &RenderContext) -> Result<Self, RenderError>

Create a new software backend

pub fn resize(&mut self, width: u32, height: u32) -> Result<(), RenderError>

Resize the backend pixmap

Trait Implementations

impl RenderBackend for SoftwareBackend

fn backend_type(&self) -> BackendType

Get the backend type

fn create_pipeline(&self) -> Result<Box<dyn Pipeline>, RenderError>

Create a pipeline for this backend

fn composite_layers( &mut self, layers: &[IntermediateLayer], context: &RenderContext, ) -> Result<Vec<u8>, RenderError>

Composite layers into final frame

fn render_layers_to_bitmaps( &mut self, layers: &[IntermediateLayer], context: &RenderContext, ) -> Result<Vec<RenderBitmap>, RenderError>

Render layers to a positioned bitmap list (libass ASS_Image style) instead of a composited frame buffer, skipping the full-frame clear/copy. The default reports the backend does not support it.

fn composite_layers_incremental( &mut self, layers: &[IntermediateLayer], dirty_regions: &[DirtyRegion], previous_frame: &[u8], context: &RenderContext, ) -> Result<Vec<u8>, RenderError>

Composite layers incrementally (dirty regions only)

fn supports_feature(&self, feature: BackendFeature) -> bool

Check if backend supports a specific feature
