Python Visio to pdf

问题

I'm trying to convert a bunch of Visio files to pdf in python. I have referenced this .doc to pdf using python and written the following code:

import comtypes.client as coms

format=17    
visio = coms.CreateObject('Visio.Application')
doc = visio.Documents.Open('map.vsd')
doc.SaveAs('map.pdf', FileFormat=format)

gives me a TypeError: call takes exactly 2 arguments (3 given)

I've been Googling and can't find the reference on how to print to pdf in Visio using python.

回答1:

You should use ExportAsFixedFormat instead SaveAs. Documentation for this function you can find here. This function can be used with a win32 and a comtypes.

win32com example

import win32com.client
visio = win32com.client.Dispatch("Visio.Application")
doc = visio.Documents.Open('map.vsd')
doc.ExportAsFixedFormat( 1, 'map.pdf', 1, 0 )

comtypes example

import comtypes.client as coms
visio = coms.CreateObject('Visio.Application')
doc = visio.Documents.Open('map.vsd')
doc.ExportAsFixedFormat( 1, 'map.pdf', 1, 0 )
