Hi,
I used this software years ago and now I needed to split another two page scanned pdf, but it does not work. I remember it worked flawless before. Briss (0.9) keeps loading the document and get sluggish, but never completes. I am using the same MacBook Pro, but the os is High Sierra. The PDF is 300 pages, so maybe that could be a problem. But when I try to divide it up in OS X Preview, the PDF size gets ten times larger. Thanks! N. |

k2pdfopt -mode crop -grid 2x1x0 myfile.pdf The 2x1x0 tells k2pdfopt to break the document into 2 columns by 1 row with 0% overlap. The -mode crop tells it to put each of those grid regions into a new page in the destination document. |

Thanks a lot, seems great! Is there setting to skip pages to crop? The first two pages are single page.
...how would I add auto straighten (-as) after the split, without the optimise rescaling? Can I do it in one pass? Last edited by nlundberg; 02-20-2020 at 08:35 AM. |

@j.p.s
Thanks, I'll check that one out too. k2pdfopt did actually did what I asked for right away. Then, as always, you see a lot of interesting options and become greedy... |

k2pdfopt is probably easier to use, especially if you don't have ghostscript installed, but croppdf might make a smaller file.

After tons of tries with the command line trying to auto straighten, I had to give up. I could not find a way to cut out the black areas from the center of the book, since after the split from double page scans, the black area is alternating side throughout the document.
I tried some other options for cleaning up but the pages ended up with slightly different sizes and I couldn't figure out how to keep page sizes. Would be fun to get it 100% right cosmetically but it is perfectly readable now. |

I used two passes:
k2pdfopt -mode crop -t -cbox1,2 0,0,1s,1s -cbox3- 0in,0in,7.186in,7.65in -cbox3- 7.186in,0in,6.18in,7.65in source.pdf -o out1.pdf k2pdfopt -mode crop -t -ac -as -w 7in -h 8in out1.pdf -o out2.pdf This forces the output page size to be 7 x 8 inches. If you are okay with variable page sizes, you can remove the -w and -h options from the second pass. |

I really like BRISS's cropping GUI, but I need destructive cropping, since I need to convert to ePub.
Is there a software that does destructive cropping instead of just hiding the data like BRISS? Preferably I want a software that can post process BRISS cropped PDF to destroy everything outside of view. |

This thread should really be deleted. The term Briss used for this software could be considered a slur to Jewish people.
