Struct ParallelRenderer

Source

pub struct ParallelRenderer { /* private fields */ }

Expand description

Parallel PDF renderer

Renders pages in parallel using multiple threads. Each page is independent, so this provides linear speedup with the number of cores.

Implementations§

Source §

impl ParallelRenderer

Source

pub fn new(num_threads: usize) -> Self

Create a new parallel renderer

§Arguments

num_threads - Number of threads to use (0 = auto-detect)

Source

pub fn render(&self, area_tree: &AreaTree) -> Result<PdfDocument>

Render an area tree to PDF using parallel processing

Pages are rendered in parallel and then combined into a single document. This is significantly faster for multi-page documents on multi-core systems.

Implementation strategy:

Pre-collect shared resources (images, opacity states) sequentially
Render individual page content streams in parallel
Combine results into final document in correct order

Source

pub fn effective_threads(&self) -> usize

Get the effective number of threads
