>> Subject: [iText-questions] Replacing PDF stream content
>>
>> Hello everybody,
>>
>> I need to change, replace a whole stream of bytes 'object'
>> from a PDF. In this case those bytes corresponds to a XFA form.
>>
>> The original PDF content is like:
>> %PDF-1 (See http://PDF-1.ora-code.com).6
>> %????
>> 1 0 obj <</Type/Metadata/...
>> ...
>> ...
>> 10 0 obj <</Filter[/FlateDecode]/Type/EmbeddedFile/Length
>> 22459>>stream ... endstream
>> 11 0 obj .......
>> ...
>>
>> So I use this piece of code:
>> PdfIndirectReference ref = writer.addToBody(new
>> PdfStream(form_field_property_value), xfa_element_ind,
>> false).getIndirectReference();
>> writer.getExtraCatalog().put(PdfName.XFA, ref);
>>
>> where "xfa_element_ind" is "10 0", and corresponds to the
>> bytes adress that I want to replace.
>>
>> As a result I get this PDF content:
>> %PDF-1 (See http://PDF-1.ora-code.com).6
>> %????
>> 10 0 obj <</Length 42101>>stream ... endstream
>> 1 0 obj <</Type/Metadata/...
>> ...
>> ...
>> ...
>> 10 0 obj <</Filter[/FlateDecode]/Type/EmbeddedFile/Length
>> 22459>>stream ... endstream
>> 11 0 obj .......
>> ...
>>
>> As one can see the content has not changed/replaced, is
>> duplicated and I don't achieve the desired result.
>>
>> How can I make a direct substitution/replacement to the
>> stream without duplicating content?
>> Is It possible?
>> How?
>>
>> I tried diferent things but I'm not able to get it!
>>
>> Thanks a lot!
