An A4 page (595.28×841.89 pt) rendered 595×841 at 72 dpi, where pdftoppm gives 596×842: the whole-page render passed hayro no size, and hayro floors the scaled page size. Content touching the right or bottom edge lost its last partial pixel at every resolution. - render: new device_pixels(pt, scale) rounds up (ignoring float noise up to 1/100 px, so Letter at 150 dpi stays 1275 px). The untiled render passes it to hayro as the width and height, still within MAX_SIDE. The partial edge pixels are anti-aliased against the white page, as the clip to the crop box already does. - ui-egui: the canvas tile grid uses the same helper instead of round(), so tiled pages get tiles for the partial row and column too. - No change to vendored hayro. Regression test: a fractional MediaBox renders 596×842 with partly covered edge pixels, 2481 px wide at 300 dpi, and a corner tile matches the whole-page render. It failed (595×841) before the fix.

//! pdfcraft-render — page rasterization and document inspection.
|
||
//!
|
||
//! **Bootstrap status (see ADR-0004):** rasterization goes straight through the `hayro` crate
|
||
//! (hayro-interpret + vello_cpu), and inspection (outline, annotations, fields, layers,
|
||
//! attachments, metadata) uses `lopdf`. Both are replaced by our own `cos`/`model` crates and the
|
||
//! DisplayList device design in M1–M2. The public API here is what the engine and UI rely on, so
|
||
//! the swap stays internal to this crate.
