Tilman Hausherr commented on PDFBOX-5323:
-----------------------------------------

This is a known weakness of java / PDFBox, text rendering mode 7, which uses clipping. This is described here
https://pdfbox.apache.org/2.0/faq.html
"Why are some texts in poor quality and not antialiased?"

> We're seeing an issue where after converting pdf document to image, the quality is degraded. This causes the text to lose the sharpness and appear pixelated. There is some pixelation even in a higher resolution image (1920x1080)
> I'm attaching screenshot of the image and the original pdf as well.
> Please help take a look at what could be the problem. Also please let me know if you need anything else.
