Hi [~tilman] could you help provide a java example for tiff -> pdf conversion
using twelvemonkeys? Thanks
Also, since we never see this blurry issue on our local machine, could the
blurry issue caused by the font library difference between local and remote
systems?

> Blurry PDF results from Tif Conversion
> --------------------------------------
>
> Key: PDFBOX-5438
> URL: https://issues.apache.org/jira/browse/PDFBOX-5438
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 2.0.24
> Reporter: Frank Zhou
> Priority: Critical
> Attachments: PartialBlurryResult.png
>
>
> When converting a tif/tiff file to a pdf using PDImageXObject, we noticed
> that the final result could be completely or partially blurry sometimes. It
> happens on our server hosted on the cloud randomly but never happens on the
> server that runs on the local machine (laptop).
> What could be the causes for this rendering issue, and could you help us with
> any suggestive actions we could take to investigate further and resolve the
> issue? We can't attach the result file because it contains our customer
> information.
> Thanks for your understanding, and we appreciate your help and support!
