Crate karet_pdf 

karet-pdf — headless, pure-Rust PDF rasterization for karet.

It wraps the hayro PDF interpreter/renderer (pure Rust, no C-sys dependencies) to turn PDF bytes into RenderedPages of straight (un-premultiplied) 8-bit RGBA pixels. A renderer such as karet-fileview can then hand those pixels to the Kitty graphics protocol (or a halfblock fallback). The crate is headless — no ratatui, no terminal — so a PDF can be turned into pixels anywhere.

Parsing happens once in Document::load; pages are rasterized on demand via Document::render_page, so a large document is not fully rendered up front.

let doc = karet_pdf::Document::load(bytes)?;
for i in 0..doc.page_count() {
    let page = doc.render_page(i, 2.0)?; // 2× the native 72-DPI size
    assert_eq!(
        page.rgba().len(),
        page.width() as usize * page.height() as usize * 4
    );
}

Structs

Document

A parsed PDF document. Load once, then rasterize pages on demand.

OutlineItem

One entry in a PDF’s navigation outline (a bookmark / table-of-contents node).

RenderedPage

A single rasterized PDF page: straight 8-bit RGBA pixels plus dimensions.

Enums

PdfError

An error loading or rasterizing a PDF document.
