Export Microsoft Visio Drawing to Image File

import aspose.diagram
from aspose.diagram import *

#// Initialize a Diagram class
diagram = Diagram(os.path.join(sourceDir, "Drawing1.vsdx"))

#// Save diagram in the png format
diagram.save("Visio_out.png", SaveFileFormat.PNG)

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

import aspose.diagram
from aspose.diagram import *

#// Initialize a Diagram class
diagram = Diagram(os.path.join(sourceDir, "Drawing1.vsdx"))
#// Save diagram as PNG
options = saving.ImageSaveOptions(SaveFileFormat.PNG)
    
#// Save one page only, by page index
options.page_index = 0

#// Save diagram in the png format
diagram.save("ExportPageToImage_out.png", options)
