wiz011 · 06-28-2020, 11:19 PM

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.
