The property caps the per-page PDF render resolution to the page’s native raster resolution, preventing rendering at a higher DPI than the embedded image and emitting the page at its native (smaller) pixel dimensions and DPI in the final output.
Only image‑dominated (scan) pages are affected; pages with text or vector content are never softened and are emitted at the requested DPI. The cap is ignored when an explicit output ImageConvertOptions.Width or ImageConvertOptions.Height is set. The default is False (no capping; every page is rendered and emitted at the requested DPI).
