@bkpsusmitaa It would help if you gave details about the version of linux you use and the version of Gimp. In another post give debian and Knoppix but.. The latest versions of Debian and Knoppix (9.1) have versions of Gimp (2.10.22) that do not support gimp-python. That leaves script-fu solutions. If you do get any answers to the problem they might come in a Gimp python plugin form, although there are flatpak / appimage versions of Gimp to overcome that problem.
To give a bit of scope to the problem, these thumbnails pulled from an example PDF. Pages typically about 1400 x 1000 pix.
@Ofnuts I put the linux deskew binary in another post along with the divide scanned images script. Then found out the images are scanned pages.I recall the straighten script, must be in my archive somewhere. recall wrong. The deskew plugin shows up bottom the Layer -> Transform menu.
