Example:

var aspose = aspose || {};
aspose.diagram = require("aspose.diagram");

originalDiagram = new aspose.diagram.Diagram("Pages.vsdx");

// initialize the new visio diagram
newDiagram = new aspose.diagram.Diagram();

// add all masters from the source Visio diagram
originalMasters = originalDiagram.getMasters();
for (var it = originalMasters.iterator(); it.hasNext();) {
    master = it.next();
    newDiagram.addMaster(originalDiagram, master.getName());
}

// get the page object from the original diagram
SrcPage = originalDiagram.getPages().getPage("Page-1");
// set page name
SrcPage.setName("new page");

// it calculates max page id
max = 0;
if (newDiagram.getPages().getCount() != 0) {
    max = newDiagram.getPages().get(0).getID();
}

for (i = 1; i < newDiagram.getPages().getCount(); i++) {
    if (max < newDiagram.getPages().get(i).getID()) {
        max = newDiagram.getPages().get(i).getID();
    }
}

MaxPageId = max;
// set page id
SrcPage.setID(MaxPageId);
// add reference of the original diagram page
newDiagram.getPages().add(SrcPage);

// remove first empty page
newDiagram.getPages().remove(newDiagram.getPages().get(0));

// save diagram in VDX format
newDiagram.save("out-CopyVisioPage.vsdx", aspose.diagram.SaveFileFormat.VSDX);
