Steps for annotation VSSM Files in Java

A basic document annotation and concatenating with

Aspose.Diagram for Python

APIs can be done with just few lines of code.

  • Load VSSM file by creating an instance of Diagram
  • Select Page via its id
  • Get annotation in Page’s Pagesheet
  • Call the remove() method to remove the comment
  • Call the save() method and pass the file name (full path) and format (VSDX) as a parameter.
  • Now you can open and use the VSDX file in Microsoft Office, Adobe PDF or any other compatible program.
