Error with PDF conversion

McBluna · Post by **McBluna** » Wed Jul 02, 2025 7:59 pm

Hello,

Environment:

Microsoft Windows Version 24H2 (Build 26120.4520)
XnView MP 1.9.2 64-Bit
Nconvert 7.221 64-Bit
Ghostscript 10.05.1 for Windows (64 bit)

I'm working on Excel VBA and PDF export. After the export, I'm using the python based tool https://github.com/abarker/pdfCropMargins to crop the white area.
After reading the wiki page and installing the latest 64-Bit Ghostscript, XnView is able to create a thumbnail and show the PDF.
I've tweaked the setting for PDFDpi in xnview.ini

Code: Select all

PDFDpi=600

to get high res view.

before pdfCropMargins

after pdfCropMargins

this is how it looks like in XnView MP

For any reason, there is an uncropped area. Also, after converting the PDF with XnView or with NConvert to PNG/WEBP.

Code: Select all

I could add autocrop, but this will remove the border from the table on the image.

I've attached both PDFs, so the issue should be reproducible.
