Aspose.PDF Viewport interface

Aspose.PDF Product Family
1

Does Aspose.PDF have an interface for interacting with measuring viewports? I can’t find anything under the name viewport in the API documentation. Specifically I would like to delete them.

I attached a pdf with two viewports in it, as well as a screenshot of how the viewports show up in the measurements menu of Bluebeam Revu.

This is the main piece of the object encoding in the pdf:
