I have written a very simple program to convert a color PDF to a TIFF with Group-4 compression. I have discovered that when I create the TiffDevice, the TiffSettings are ignored unless I also include a Resolution object.
Thanks for your inquiry. I have tested the scenario using Aspose.Pdf for Java 10.0.0 and managed to observe the reported issue. For further investigation, I have logged an issue in our issue tracking system as PDFNEWJAVA-34739 and also linked your request to it. We will keep you update via this thread regarding the issue status.
Please feel free to contact us for any further assistance.
