Struct RasterRenderer 

pub struct RasterRenderer { /* private fields */ }

Raster renderer that converts area trees to PNG or JPEG images

This renderer uses a two-stage process:

1. Convert the area tree to SVG using SvgRenderer
2. Rasterize the SVG to bitmap using resvg/tiny-skia

Implementations

impl RasterRenderer

pub fn new(dpi: u32) -> Self

Create a new raster renderer with specified DPI

Arguments

• dpi - Target resolution in dots per inch (typical values: 72, 96, 150, 300)

Examples

use fop_render::RasterRenderer;

let renderer = RasterRenderer::new(300); // 300 DPI for print quality

pub fn render_to_raster( &self, area_tree: &AreaTree, format: RasterFormat, ) -> Result<Vec<Vec<u8>>>

Render an area tree to raster images (one per page)

Arguments

• area_tree - The area tree to render
• format - The output format (PNG or JPEG)

Returns

A vector of byte vectors, one for each page. Each inner vector contains the encoded image data (PNG or JPEG).

Errors

Returns an error if SVG generation or rasterization fails.

Trait Implementations

impl Default for RasterRenderer

fn default() -> Self

Create a renderer with default 96 DPI (Windows standard)
