Scantools is a high-quality library and a matching set of command-line programs for the handling and manipulation of scanned documents. At present, the tools can convert image files to PDF/A. Files in JBIG2, JPEG, and JPEG2000 format are directly included in the PDF, other files are compressed in a lossless manner. HOCR files, which are produced by optical character recognition programs such as ‘tesseract’, can be used to make the PDF file searchable. The resulting files comply with the ISO PDF/A standard for long-term archiving of digital documents and offer compression rates comparable to that of the DJVU file format. There are currently three command-line utilities.
scantools.image2pdf converts images to a PDF/A compliant PDF file.
scantools.hocr2any converts HOCR files to text or renders them as raster graphics or PDF files.
scantools.ocrPDF adds a text layer to a graphics-only PDF file, without re-encoding graphics data or otherwise modifying file content.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snapd can be installed from Manjaro’s Add/Remove Software application (Pamac), found in the launch menu. From the application, search for snapd, select the result, and click Apply.
Alternatively, snapd can be installed from the command line:
sudo pacman -S snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install scantools, simply use the following command:
sudo snap install scantools
Browse and find snaps from the convenience of your desktop using the snap store snap.
