Struct HeadlessRenderer

Source

pub struct HeadlessRenderer {
    pub width: f32,
    pub height: f32,
    pub dpi_factor: f32,
}

Expand description

Headless renderer for CPU-based screenshot capture.

Wraps cpurender::render() with headless-specific configuration. This is separate from CpuCompositor (which implements the Compositor trait for the WebRender software fallback path). The headless renderer operates entirely without WebRender.

Implementations§

Source §

impl HeadlessRenderer

Source

pub fn new(width: f32, height: f32, dpi_factor: f32) -> Self

Create a new headless renderer with the given dimensions.

Source

pub fn render_frame( &self, display_list: &DisplayList, renderer_resources: &RendererResources, ) -> Result<AzulPixmap, String>

Render a display list to a pixel buffer.

Returns an AzulPixmap that can be saved as PNG.
