Convert Visio to Images formats

Exporting Diagrams to Image File Formats

This article explains how to export a Microsoft Visio diagram to an image 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 image below shows a VSD file about to be saved to PNG format. You can use other diagram formats (VSS, VSSX, VSSM, VDX, VST, VSTX, VSTM, VDX, VTX or VSX) as well.

The example VSD file.

To export a diagram to an image:

• Create an instance of the Diagram class.
• Call the Diagram class' Save method and set the image format you want to export to.The output image file looks like the original file.

The output PNG file.

Exporting to Image File 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("ExportToImage.vsd")

# Save as PNG
diagram.save("ExportToImage_Out.png", SaveFileFormat.PNG)

jpype.shutdownJVM()

It is also possible to save a particular page to image, instead of the entire document:

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

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

# load diagram
diagram = Diagram("ExportToImage.vsd")

# Save diagram as PNG
options = ImageSaveOptions(SaveFileFormat.PNG)

# Save one page only, by page index
options.setPageIndex(0)

# Save resultant Image file
diagram.save("ExportPageToImage_Out.png", options)

jpype.shutdownJVM()
