Daniel Persson commented on PDFBOX-4917:
Hi again, update.
I did a git checkout on the 2.0 branch and tested to run the application there,
and the image created on that branch did not have the issue mentioned above.
Perhaps you can just verify if solved in the upcoming release. If so, we will
be waiting patiently for the release of the coming weeks.
Best regards
Daniel

Summary: Images are blurry after updating to 2.0.20
Key: PDFBOX-4917
URL: https://issues.apache.org/jira/browse/PDFBOX-4917
Project: PDFBox
Issue Type: Bug
Reporter: Daniel Persson
Attachments: issue.pdf, pdfbox-app-2.0.19.jpg, pdfbox-app-2.0.20.jpg
Hi team.
We have noticed that after updating to PDFBox to 2.0.20 some images are blurry
and unreadable even in 300 DPI.
We have rendered both these images with the same parameters just different
versions of PDFBox.
{code:java}
java -jar pdfbox-app-2.0.19.jar PDFToImage -dpi 300 -quality 0.95 issue.pdf
java -jar pdfbox-app-2.0.20.jar PDFToImage -dpi 300 -quality 0.95
issue.pdf{code}
Hope we can find a solution to this problem, perhaps it is related to
PDFBOX-4516?
Best regards
Daniel
