The following code sample shows how to get changes coordinates.

Coordinates calculation example

try (Comparer comparer = new Comparer("C:\\source.pdf")) {

    CompareOptions compareOptions = new CompareOptions();
    compareOptions.setCalculateCoordinates(true);"C:\\result.pdf", compareOptions);

    ChangeInfo[] changes = comparer.getChanges();
    for (ChangeInfo change : changes) {
        System.out.println(String.format("Change Type: %d, X: %f, Y: %f, Text: %s", change.getType(), change.getBox().getX(), change.getBox().getY(), change.getText()));
