@Gaaks--it would be most helpful if you could post some examples from the source PDFs that you discussed so that I could try some different options on them.
(Another way would be to send me samples via private message.) Last edited by willus; 06-28-2020 at 08:31 AM. |

Gaps regarding of source resolution
I have two scanned PDFs (the same edition, design, fonts, etc.) created from pictures. One is created from 750 x 1182 source pictures, another one from 650 x 1025 source pictures. Converted PDF from the 750x1182 source has a lot of "gaps", the conversion of 650x1025 is almost excellent. When 750x1182 PDF is exported to images (using PDF XChange Viewer), these pictures resized to 650 x 1025, created a new PDF, and then converted, all is fine.
The target device is Huawei P20 lite mobile phone, with resolution 1080x2110 on 150 dpi (it is a visible PDF area in PocketBook reader application), additional options -om 0.2 -y -de 3.0 -gtc 0.2 (the problem exists without these options). I can on some file-sharing site post the samples of source and resulting PDFs, and the screenshot of settings as well. |

If you could post example pages from the two different source PDF files, that would help the most. It's hard to know what you mean by "a lot of gaps" vs. "almost excellent" without some visuals.

I'll upload them later. "A lot of gaps" means something like below:
650 x 1025 XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX (the result is one page) 750x1182 XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX (the result are two pages) In most cases, the problem occurs when on the source is the end of one page and the beginning of the next page. Also, somewhere exists a problem like this: XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX (P.S. the forum editor changes my "examples", the page with one row is the first one) Last edited by wiz011; 06-30-2020 at 10:26 AM.

Please attach sample pages from the source PDF files. You can even use k2pdfopt to create the sample pages:
k2pdfopt -mode copy -n source.pdf -p 10-15 -o pages_10_to_15.pdf |
