To create a new document as a blank PDF.

# use the empty constructor to create a blank PDF

# optionally perform some document processing using read write operations 
# found under 'Editing Page Content' or 'Page Manipulation'

# save the document to the filesystem
doc.Save(output_filename, SDFDoc.e_linearized)

# optionally save the document to a memory buffer
buffer = doc.Save(SDFDoc.e_linearized)
