How to find the absolute position and dimension of a field?
Given an field name, is it possible to find the absolute position and dimension of that particular field (getLeft()
, getTop()
, getWidth()
, getHeight()
)?

First part of your question:
Suppose that you have an AcroFields
instance (form
), either retrieved from a PdfReader
(read only) or a PdfStamper
instance, then you can get the field position of the first widget that corresponds with a specific field name
like this:
Rectangle rectangle = form.getFieldPositions(name).get(0).position;
Note that one field can correspond with multiple widgets. For instance, to get the second widget, you need:
Rectangle rectangle = form.getFieldPositions(name).get(1).position;
Of course: you probably also want to know the page number:
int page = form.getFieldPositions(name).get(0).page;
Second part of your question
Fields correspond with widget annotations. If you know the page number of the widget annotation, you could get the page dictionary and inspect the entries of the /Annots
array. You'll have to loop over the different annotations, inspecting each annotation's /Rect
entry. Once you find a match, you need to crawl the content for the field that corresponds with the annotation. That's more work than can be provided in a code sample on this site.
