Specifies extra arguments specifically for GhostScript. Arguments should only be passed as a “string.”
Example
pdftodjvu --gsarg="-dNOSAFER -c << /GenericResourceDir (C:/GSResources/) >> setsystemparams" asianfonts.pdf asianfonts.pdf.djvu
NOTE: Earlier versions of pdftodjvu required this argument to access third-party fonts. This is no longer necessary.
