Enum LayoutSrc 

pub enum LayoutSrc<'a> {
    PageImage(&'a RgbImage),
    Raw(&'a RgbImage),
}

What a layout inference call receives per page — which resize kernel packs the 640×640 model input depends on it (docling parity, #58-branch):

docling’s layout stage runs on page.get_image(scale=1.0) — the point-sized page image (pdfium at 1.5×, PIL-BICUBIC down) — which its RT-DETR processor then stretches to 640×640 with PIL BILINEAR (preprocessor_config.json: do_pad: false, resample: 2; no letterbox, no normalize beyond /255). PageImage is that image and goes through the byte-exact PIL kernel. Raw is any other bitmap (the browser path’s canvas render, METS/TIFF page scans) and keeps the legacy Triangle stretch.

Variants

PageImage(&'a RgbImage)

The scale-1.0 page image (PdfPage::image_layout), docling-exact.

Raw(&'a RgbImage)

Any other page bitmap — legacy stretch.
