Some pdf Documents masked Black

Doconut Product Family
1

Hello,

I’m experiencing a problem with some PDF documents. When I open the PDFs, they look completely normal. However, in the Doconut Viewer, the PDFs appear mostly blacked out, and the majority of the content is not visible.

Here are my questions:

  • Is this an issue related to the Doconut Viewer, or is there something wrong with the PDF itself?
  • Could the PDF’s color space be causing this? The PDF was originally created using a scanner.
  • Are there any known issues with scanned PDFs that might be relevant?

nterestingly, after reprinting the file using a tool like “Microsoft Print to PDF,” the issue disappears, and the PDF displays perfectly in the viewer.

I’ve attached an image from the viewer and the problematic PDF to provide more context.
