Hi Stefan, yes, PDFBox is capable of doing this. To crop the page to the dimensions you need you can use
PDPage.setCropBox [http://pdfbox.apache.org/docs/1.8.8/javadocs/org/apache/pdfbox/pdmodel/PDPage.html#setCropBox(org.apache.pdfbox.pdmodel.common.PDRectangle)] As John pointed out, the SuperimposePage example will give you the basics to import and 'mount' the page into a new or existing PDF. Only thing is to get the coordinates from the mouse and translate that to the dimensions for the rectangle in PDF.
