Q: We need to update an existing stamp in a PDF page and change the text on it. How can we do that using Qoppa’s Java PDF annotating component, jPDFNotes?
Q: You will need to remove the existing rubber stamp and create a new stamp with the same properties but different text.
The example below shows how to remove an existing rubber stamp and create a new stamp with the following text “My New Stamp” and add the new rubber stamp to the first page of a PDF document.
// get current stamp (assuming only one annotation on the first page) RubberStamp currentStamp = (RubberStamp) pdfEditor.getDocument().getIPage(0).getAnnotations().get(0); // create a new rubber stamp with new text and same color RubberStamp newRubberstamp = pdfNotesBean.getMutableDocument().getAnnotationFactory().createRubberStamp("My New Text",currentStamp.getColor()); // copy all properties from current stamp to new stamp newStamp.setRectangle(currentStamp.getRectangle()); newStamp.setName(currentStamp.getName()); newStamp.setSubject(currentStamp.getSubject()); newStamp.setContents(currentStamp.getContents()); newStamp.setRotation(currentStamp.getRotation()); // remove current stamp pdfNotesBean.removeAnnotation(currentStamp, 0); // add new stamp pdfNotesBean.addAnnotation(newStamp, 0); |
