Hi,
That's why I mentioned to look at the log messages, there would be one
mentioning that a fallback font is used.
The alternative would be to implement your own FontMapper. Call
FontMappers.set() with your own FontMapper. To see how to implement your
own, look at the source code of FontMapperImpl class.
All this is not trivial, probably a several days of work. The best would
be to expand the "lastResortFont" part to support all standard 14 fonts
instead of just having LiberationSans.

I think the issue is that the required font it not on the Azure

The java code is included below:

Hi,
I tested with 3.0.1 and got one log message:
Unexpected XRefTable Entry: 0 24
that's because that line is " 0 24" instead of "0 24". However
that doesn't seem to have a negative effect. Here's how the image looks:

Hi,
We'd need the PDF file, please upload to a sharehoster. Your attachments
(all of them) didn't get through.
Also try to use the latest snapshot
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/3.0.2-SNAPSHOT/
and look at the log messages.

Hi,
I am using PDFBox to render a PDF to a .png image. In the past, I
used version 2.0.23 which worked without issue. When the image is
rendered in verion 3.0.1, the text part of the PDF document does not
properly convert the Font (Times Roman). How can I fix this issue?
I have attached the images to show the comparison of what is being
rendered in version 3.0.1 versus 2.0.23.
Thanks for any help you can provide.
