Topic: xobject streams in acroform-fields...

I am just curious. Does anyone know how to render the background XObject in a Formfield?

We want to copy (Rich or not Richt-)Text fields from one PDF to another. Works fine.

But if we change something in the annot-layer of a button (e.g. the "/RV") any Adobe Reader or Adobe Pro still shows the old text in the PDF - because there is a rendered XObject under /AP << /N >> of the Field-Annot.

I know how to get the /N stream (which is not that hard). But I cant get out, how to create such a stream.

Do I have to parse the RichText Value of the field?

We can/could use several libraries, also PDF-SDK. But still, no clue how to solve this issue.

Anybody knows how to render the Value to an XObject stream? (of a Textfield with Richtext? Or even just simply normal Text?)

Because if I change the Annot Value of a RichText Formfield in a PDF, and do some flattening, the flatten method only takes the background XObject and removes the annot - which leads to: the changes are simply lost.

Ask if You didnt understand my poor english =)
