Hi,
I have a spire.doc pro license. I am using the code from the spire.doc tutorials (Tutorials/Spire.Doc/Spire.Doc-Program-Guide/How-to-Convert-Word-to-Tiff.html) to convert a .doc files into .tif files. On my local machine the files convert without issue. However when converting on a Windows 2016 Server, with the process running as a service, the barcodes fail to convert correctly. Examples attached.
I am using .Net Framework 4.5 and Spire.doc 8.6.3.
