Build system has moved to meson, so rewrite the SlackBuild based on the standard meson template. The manpage now requires "sphinx" to be built, which is a large python package with many dependencies. Patch out the building of same by default, and add the optional dep of Sphinx and the option SPHINX=true for those that want it. Update the README file to reflect this build option/optional dep, and re-paragraph it to make it more readable. Signed-off-by: Willy Sudiarto Raharjo <willysr@slackbuilds.org> |

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 disaligned centering and rotation of pages and will automatically straighten each page by rotating it to the correct angle. This process is called "deskewing". Note that the automatic processing will sometimes fail. It is always a good idea to manually control the results of unpaper and adjust the parameter settings according to the requirements of the input. Each processing step can also be disabled individually for each sheet. Input and output files can be in either .pbm, .pgm or .ppm format, thus generally in .pnm format, as also used by the Linux scanning tools scanimage and scanadf. Conversion to PDF can e.g. be achieved with the Linux tools pgm2tiff, tiffcp and tiff2pdf. This is a fork of the original unpaper software by D.E. "Flameeyes" Petteno'. BUILD OPTIONS: SPHINX => set to 'true' to build the manpage for unpaper, which now requires "Sphinx" (available in SBo), which is a large python package with many dependencies. Thus, it is disabled by default.
