I have an existing editable PDF which is not generated with i-text.
And I am reading the values from pdf and i have to make the editable columns
readonly.
here is my following snippet of code
PdfCopyFields copy = new PdfCopyFields(new
FileOutputStream("C:\\Sample.pdf"));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfStamper stamper = new PdfStamper(reader, baos);
AcroFields acroFields = stamper.getAcroFields();
PRAcroForm acroForm = reader.getAcroForm();
for(FieldInformation info :acroForm.getFields()){
acroFields.setFieldProperty(info.getName(), "clrfflags",
PdfFormField.FF_READ_ONLY, null);
acroFields.setFieldProperty(info.getName(), "setfflags",
PdfFormField.FF_READ_ONLY, null);
acroFields.regenerateField(info.getName());
}
copy.addDocument(new PdfReader(reader.getPageContent(0)));
copy.close();
and i get this following error
Exception in thread "main" java.io.EOFException
