Struct SkiaDevice 

pub struct SkiaDevice { /* private fields */ }

tiny-skia based raster device.

Implementations

impl SkiaDevice

pub fn new(width: u32, height: u32) -> Self

Create a new device with the given page dimensions and default PNG output.

Defers the full-page pixmap allocation — only a 1×1 placeholder is created here. The full pixmap is allocated lazily in replay_and_show only when the non-banded rendering path is needed.

pub fn with_sink_factory( width: u32, height: u32, sink_factory: Box<dyn PageSinkFactory>, ) -> Self

Create a new device with a custom page sink factory.

pub fn set_use_viewport_path(&mut self, on: bool)

Route rendering through the viewport pipeline. Used by the visual test runner’s --device viewport-png mode.

pub fn set_layer_set(&mut self, layer_set: LayerSet)

Replace the device’s OCG visibility overrides.

The empty default has every layer fall back to its default_visible baked into the display list. Callers building a layer panel hand in a populated LayerSet each render pass.

pub fn layer_set(&self) -> &LayerSet

Read-only view of the device’s current OCG visibility overrides.

pub fn pixmap(&self) -> &Pixmap

Get the underlying pixmap (for testing).

pub fn set_system_cmyk_bytes(&mut self, bytes: Arc<Vec<u8>>)

Set the system CMYK ICC profile bytes for ICC-aware rendering.

pub fn set_no_aa(&mut self, no_aa: bool)

Disable anti-aliasing for all fill/stroke operations.

Trait Implementations

impl Drop for SkiaDevice

Available on crate feature ps-device only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl OutputDevice for SkiaDevice

Available on crate feature ps-device only.

fn fill_path(&mut self, path: &PsPath, params: &FillParams)

Fill a path with the given color.

fn stroke_path(&mut self, path: &PsPath, params: &StrokeParams)

Stroke a path with the given parameters.

fn clip_path(&mut self, path: &PsPath, params: &ClipParams)

Intersect the current clip region with the given path.

fn init_clip(&mut self)

Reset clipping to the full page.

fn erase_page(&mut self)

Erase the page (fill with white).

fn show_page(&mut self, output_path: &str) -> Result<(), String>

Output the current page (e.g., save PNG) and return Ok/Err.

fn draw_image(&mut self, sample_data: &[u8], params: &ImageParams)

Draw an image from raw sample data.

fn paint_axial_shading(&mut self, params: &AxialShadingParams)

Paint an axial (linear) gradient shading.

fn paint_radial_shading(&mut self, params: &RadialShadingParams)

Paint a radial gradient shading.

fn paint_mesh_shading(&mut self, params: &MeshShadingParams)

Paint a Gouraud-shaded triangle mesh.

fn paint_patch_shading(&mut self, params: &PatchShadingParams)

Paint a Coons/tensor-product patch mesh.

fn paint_pattern_fill(&mut self, params: &PatternFillParams)

Paint a tiled pattern fill.

fn page_size(&self) -> (u32, u32)

Page dimensions in device pixels.

fn replay_and_show( &mut self, list: DisplayList, output_path: &str, ) -> Result<(), String>

Replay a display list and write output in one step.

fn finish(&mut self) -> Result<(), String>

Wait for any pending background render to complete.

fn set_trim_box(&mut self, _llx: f64, _lly: f64, _urx: f64, _ury: f64)

Set the trim box for the next page (PDF points, lower-left origin). Only meaningful for PDF output; other devices ignore this.

fn finish_with_context(&mut self, _ctx: &Context) -> Result<(), String>

Called after interpretation finishes, with access to the interpreter context.

fn as_any(&self) -> &(dyn Any + 'static)

Downcast to a concrete type. Override in implementations that need to be accessed after rendering (e.g., PdfDevice for in-memory output).
