Convert Visio to PDF format

Exporting to PDF

Aspose.Diagram for Python via Java directly writes the information about the API and Version Number in output documents. For example, upon rendering a Drawing to PDF, Aspose.Diagram for Java populates Application field with value ‘Aspose.Diagram’ and PDF Producer field with a value, e.g ‘Aspose.Diagram 17.9’.

Please note that you cannot instruct Aspose.Diagram for Python via Java to change or remove this information from output Documents.

This article explains how to export a Microsoft Visio diagram to PDF using Aspose.Diagram for Python via Java.

Use the Diagram class' constructor to read the diagram files and the Save method to export the diagram to any supported image format.

The VSD diagram is the example drawing file to export PDF. You can use other diagram formats (VSS, VSSX, VSSM, VDX, VST, VSTX, VSTM, VDX, VTX or VSX) as well.

To export VSD diagram to PDF:

1. Create an instance of the Diagram class.
2. Call the Diagram classs Save method and set the output format to PDF.

Exporting to PDF Programming Sample

import jpype
import asposediagram
jpype.startJVM()
from asposediagram.api import *

lic = License()
lic.setLicense("Aspose.Total.Product.Family.lic")

# Call the diagram constructor to load diagram from a VSD file
diagram = Diagram("ExportToPDF.vsd")

# Save as PDF file format
diagram.save("ExportToPDF_Out.pdf", SaveFileFormat.PDF)

jpype.shutdownJVM()

Split Multiple Pages

Aspose.Diagram for Java allows splitting multiple pages while converting the Microsoft Visio Diagram to PDF. The following code snippet shows the functionality.  

import jpype
import asposediagram
jpype.startJVM()
from asposediagram.api import *

lic = License()
lic.setLicense("Aspose.Total.Product.Family.lic")

# Call the diagram constructor to load diagram from a VSDX file
diagram = Diagram("Network Diagram_start.vsdx")
# Options when saving a diagram into the PDF format
options = PdfSaveOptions()
# set SplitMultiPages option
options.setSplitMultiPages(True)
# save in PDF format
diagram.save("SplitMultiPages.pdf", options)

jpype.shutdownJVM()
