Thanks for being patient. Please note that there is no “DISPLAYBARCODE merge field”. The DISPLAYBARCODE field has following field code schema:
The DISPLAYBARCODE field has no separator and MS Word layout engine render bar code. So, Aspose.Words supports described scenario with saving result to docx format.
To support this field type completely we need to add new field type and field class with field code annotation and implement generation and rendering of bar code in rendered documents.
However, before we proceed further and implement your request, could you please let us know if you also want to save the document in some rendered format like PDF/XPS/Images? Can you please describe your scenario/usecase in detail? Thanks for your cooperation.
