my current code - avoded memoery stream and using file stream that did not
help either (:. Same orignal files would NOT be corrupt if i re processed
them. This is why i am having hard time. not consitant here.
public static void WaterMarkPdf(string sourceFile, string destinationFile,
string waterMark)
{
PdfReader reader = new PdfReader(sourceFile);
using (FileStream fStream = new FileStream(destinationFile,
FileMode.Create, FileAccess.ReadWrite))
{
PdfStamper pdfStamper = new PdfStamper(reader, fStream);
// process every page in the pdf file
for (int i = 1; i <= reader.NumberOfPages; i++)
{
Rectangle pageSize = reader.GetPageSizeWithRotation(i);
PdfContentByte pdfPageContents =
pdfStamper.GetUnderContent(i);
PdfAnnotation annotation =
PdfAnnotation.CreateText(pdfStamper.Writer,
new
Rectangle(200f, 400f, 300f, 500f), waterMark,
"Digital Watermark", false, "Key");
//digital water marking
annotation.Flags = PdfAnnotation.FLAGS_NOVIEW |
PdfAnnotation.FLAGS_INVISIBLE |
PdfAnnotation.FLAGS_HIDDEN;
pdfStamper.AddAnnotation(annotation, i);
pdfPageContents.BeginText();
BaseFont baseFont =
BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, Encoding.ASCII.EncodingName,
BaseFont.NOT_EMBEDDED);
pdfPageContents.SetFontAndSize(baseFont, 10);
pdfPageContents.SetRGBColorFill(225, 224, 223);
// visible water marking
Rectangle pdfCropBox = reader.GetCropBox(i);
float posX = pdfCropBox.Width < pageSize.Width ?
pdfCropBox.Width : pageSize.Width;
float posY = pdfCropBox.Height < pageSize.Height ?
pdfCropBox.Height : pageSize.Height;
pdfPageContents.ShowTextAligned(PdfContentByte.ALIGN_RIGHT, waterMark,
posX - 50,
posY - 15,
0);
pdfPageContents.EndText();
pdfStamper.Writer.CloseStream = false;
pdfStamper.FormFlattening = true;
}
pdfStamper.Close();
}
}
Thanks
