I am trying to add an annotation to PDFs created from scans. The the
AcroForm object in the Reader is null. How do i get around this?
Here is my code:
private void AddAnnotation(string outputFile, byte[] data, string text)
{
PdfReader reader = newPdfReader( data );
PdfStamper stamper = new PdfStamper(reader, new
FileStream(outputFile, FileMode.Open));
Rectangle rect = new Rectangle(200f, 25f, 400f, 40f);
PdfContentByte pcb = newPdfContentByte(stamper.Writer);
pcb.SetColorFill(iTextSharp.text.Color.BLACK);
PdfAnnotation anno = PdfAnnotation.CreateFreeText(stamper.Writer,
rect,
text, pcb);
anno.Flags = PdfAnnotation.FLAGS_PRINT;
anno.Color = Color.WHITE;
stamper.AddAnnotation(anno, 1);
stamper.Close();
}
This works fine on PDFs created with acrobat, but the ones that we
have scanned in seem to get the error "Dict object required" after i
atry to add the annotation.
Any ideas?
