Is checking the order of the page annotations the best way to go about this?
{quote}
To be honest, I don't know. But for your file it seems to be.
{quote}
how are you able to view all of the annotations in the tree structure
{quote}
This is from PDFDebugger. You could get the named order by altering this code:
{code}
PDAcroForm acroForm = document.getDocumentCatalog().getAcroForm(null);
if (acroForm == null)
{
return;
}
Set<COSDictionary> dictionarySet = new HashSet<>();
for (PDAnnotation annotation : page.getAnnotations())
{
dictionarySet.add(annotation.getCOSObject());
}
for (PDField field : acroForm.getFieldTree())
{
for (PDAnnotationWidget widget : field.getWidgets())
{
// check if the annotation widget is on this page
// (checking widget.getPage() also works, but it is sometimes
null)
if (dictionarySet.contains(widget.getCOSObject()))
{
rectMap.put(widget.getRectangle(), "Field name: " +
field.getFullyQualifiedName());
}
}
}
{code}
The change would be to go through the annotations and then see which field has
that annotation widget.

> I am in the process of converting a pdf into html. The pdf i am using has tab
> numbers set on its fields.
> This is where i run across an issue. I am trying to extract the tab number
> from the pdf fields but i dont think the library offers that. I would need
> that value in order to set the tabindex when I create the corresponding html
> elements.
> The pdf i am using is[^DummyPdf.pdf]
