How to remove field annotation

We have form field with multiple annotations, and need to remove just few of them and keep others. When trying to remove annotation directly from collection we get java.lang.UnsupportedOperationException

Hi John,

Thanks for your inquiry. We can remove the Field Annotation as following but I am afraid it removes all annotations of the field. So I have logged a ticket PDFJAVA-36068 in our issue tracking system to remove a specific field annotation. We will notify you as soon as it is resolved.

// ...

if (field.size() > 0) {
    @SuppressWarnings("unchecked")
    Iterator iterator = field.iterator();
    int i = 1;

    while (iterator.hasNext()) {
        Annotation annot = iterator.next();
        System.out.println("field annotation " + annot.getFullName() + " Position: " + annot.getRect() + " field count:" + i);

        // iterator.remove();

        if (i == 2)
            pdf.getForm().delete(annot.getFullName());

        i++;
    }
}

// ...

We are sorry for the inconvenience.

Best Regards,

Hi John,

Thanks for your patience.

We have further investigated earlier reported PDFJAVA-36068 and have found that you can delete the specific annotation after creation and reload the document.

First you need to remove following lines from your code snippet to create the sample:

if (i==2)
pdf.getForm().delete(annot.getFullName());

Then use the the following snippet to delete one of the annotations.

[Java]

Document pdf = new Document(myDir + "formoutput.pdf");
System.out.println(pdf.getPages().get_Item(1).getAnnotations().size());

for (Annotation a : (Iterable) pdf.getPages().get_Item(1).getAnnotations()) {
    System.out.println(a.getRect());

    // Delete the specific annotation
    if (new Rectangle(150, 0, 250, 100).equals(a.getRect()))
        pdf.getPages().get_Item(1).getAnnotations().delete(a);
}

pdf.save(myDir + "formoutput2.pdf");
