Missing pdf 14 base fonts when converting to tiff file

Hi. I am dealing with an issue when converting PDF to TIFF files. TIFF files don’t contain text that is part of pdf’s standard 14 fonts. This issue is present when running this on red hat system. Fonts that should be used as a replacement for those 14 fonts are present in a system (nimbus fonts) but are still not shown in images that are made from TIFF files. Has anyone else had similar issue and can advise me on it. I would be very grateful for any information that I can get. Thank you.

Can you please provide the code you are using to convert the PDF to TIFF and specify the version of Aspose.PDF you are using?
