I loaded from a file and tried to render the page using RenderPageToDC and I get unexpected results, see the attachments.

This one is messed up:

This is how it suppose to look:

It seems to me that it doesn't render the gradients correctly. I also get the same result when rendering to a file, I tried multiple different formats.

Library version: 18.11

Embarcadero® Delphi 10.4 Version 27.0.38860.1461

Thank you for the help in advance.

Hi Serge,

how the original pdf was made?
What type of images are embedded?
It would be good to have the original pdf...

Cheers and welcome here,
Ingo

I see the same issues with your PDF. Try selecting the PDFIUM renderer, which seems to do a better job.
