A quick question, I am confused as to what the “Convert Add-on” license actually does? Is this a separate DLL? Or does it just enable functionality of PDFNet.dll?
If I understand this correctly, the “Convert” feature is basically the ability to use the virtual print driver. Is that right?
Also this item concerns me: Support for high quality conversion from Word, Excel, Outlook, or PowerPoint via Office interop.
Does this mean I have to Word installed on my server to convert? Is it using Word automation?
Most Add-ons simply unlock specific API-s/functionality within PDFNet.DLL (i.e. you don’t need extra DLLs).
It MS Office is installed, MS Office files will be converted directly (via COM intretop) and not via the virtual printer driver.
It MS Office is not installed, MS Office files will be converted indirectly via PDFTron PDFNet Virtual Printer.
PDFNet Converter Add-on also includes a number of direct converters (e.g. PDF->XPS, XPS->PDF, PDF/XPS->SVG, TXT, to/from EMF/WMF, to/from images, to/from HTML, etc) that do not reply on either Office or virtual printer driver.
For more info please see pdftron.PDF.Convert namespace in PDFNet API Reference.
