Convert Visio Pages to Images in vb.net

I have been fooling around with Visio automation since attempting to help a friend with a project that did so. In the course of this I did this code snippet to convert the Visio page to an image. The code loops through and takes each page and converts it to an image. Pretty basic. I have not posted in a while and my apologies to those of you who were wondering…. Smile

Here is the code….

Sub SaveAsImage()
‘ creates an invisible Visio instance, opens a document, then
‘ saves all pages in the document as jpg images using
‘ page name and page number as file name
 
    Dim vsoApp As Visio.Application
    Dim vsoDoc As Visio.Document
    Dim PathName As String, jpgName As String
    Dim pg As Visio.Page
  
    Set vsoApp = CreateObject(“Visio.InvisibleApp”)
    ‘ SET PATH/FILENAME BELOW TO VSD ON YOUR SYSTEM
    Set vsoDoc = vsoApp.Documents.Open(“c:\TEST\test.vsd”)
  
    PathName = vsoApp.Documents(1).Path      ‘ Set pathname to that of first document
           
    For Each pg In vsoApp.ActiveDocument.Pages
        jpgName = PathName & Format(pg.Index, “0#”) & ” ” & pg.Name & “.jpg”
        pg.Export jpgName
    Next
   
    vsoDoc.Close
    vsoApp.Quit
    Set vsoDoc = Nothing
    Set vsoApp = Nothing
 
End Sub
