Post-processing of scanned and photocopied book pages

unpaper is a post-processing tool for scanned sheets of paper, especially for book pages that have been scanned from previously created photocopies. The main purpose is to make scanned book pages better readable on screen after conversion to PDF. Additionally, unpaper might be useful to enhance the quality of scanned pages before performing optical character recognition (OCR). unpaper tries to clean scanned images by removing dark edges that appeared through scanning or copying on areas outside the actual page content (e.g. dark areas between the left-hand-side and the right-hand-side of a double-sided book-page scan). The program also tries to detect misaligned centering and rotation of pages and will automatically straighten each page by rotating it to the correct angle. This process is called "deskewing".

Checksums e datas de observação

For an APT source, signature verification authenticates the repository metadata chain and the Packages index containing this source-reported artifact digest. It does not certify package safety.

7.0.0-14.fc43 / aarch64Observed Sep 1, 2026 to Sep 1, 2026

Verification status: Metadata observed; artifact bytes were not independently fetched or hashed by this catalog import. The digest below is source-reported.

Source-reported sha256: ebc10e6a2b343da209df4b4b1c75571dcb2ee70a55bd636cda61f8e41a7930aa

After downloading that exact artifact, compare its bytes with the source-reported expected digest:

printf '%s  %s\n' 'ebc10e6a2b343da209df4b4b1c75571dcb2ee70a55bd636cda61f8e41a7930aa' 'unpaper-7.0.0-14.fc43.aarch64.rpm' | sha256sum --check --strict -

A match establishes equality with the repository metadata value. It does not establish safety or catalog-side artifact retrieval.
