Frank Zhou updated PDFBOX-5438:
-------------------------------
Description:
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}
// Tiff -> PDF conversion

final BufferedImage bufferedImage = reader.read(i);

bufferedImage.getHeight());
final PDPage page = new PDPage(pageSize);
document.addPage(page);
