------------------------------------
Hi [~tilman] could you help provide a java example for tiff -> pdf conversion
using twelvemonkeys? Thanks
> 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!

> {code:java}

> final int numPages = reader.getNumImages(true);

> final BufferedImage bufferedImage = reader.read(i);
> final PDRectangle pageSize =
