PDF file is not being watermarked using aspose.pdf

Hi,

We are facing a issue in watermarking pdf files using functionality given in aspose.pdf and aspose.pdf.kit

Some of the pdf files are being watermarked while others are not.

Please let us know why this is happening as we are unable to trace the issue.

Please find below the code snippet, we are using to watermark a pdf file:

Aspose.Pdf.Kit.License pdfKitLicense = new Aspose.Pdf.Kit.License();
pdfKitLicense.SetLicense("Aspose.Total.lic");
Aspose.Pdf.License pdfLicense = new Aspose.Pdf.License();
pdfLicense.SetLicense("Aspose.Total.lic");
PdfFileStamp fileStamp = new PdfFileStamp(sourceFile, watermarkedOutputPath);
Stamp watermarkStamp = new Stamp();
Watermark oWatermark = new Watermark(AdamContext.Current.AdamApplication);
oWatermark.Load("MyWatermark2");
string imagePath = oWatermark.Image.GetPath();
using (System.IO.Stream stream = new System.IO.FileStream(imagePath, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite, System.IO.FileShare.Read))
{
watermarkStamp.BindImage(stream);
watermarkStamp.SetOrigin(90, 400);
watermarkStamp.Rotation = 360;
watermarkStamp.Opacity = float.Parse("0.5");
fileStamp.AddStamp(watermarkStamp);
fileStamp.Close();
}

But in your code snippet, you have tried to put stamp at position (90, 400)

watermarkStamp.SetOrigin(90, 400);



Therefore the stamp is out of visible page area. In order to make the stamp visible, customer may
just change SetOrigin() parameters.


For example:

watermarkStamp.SetOrigin(90, 90);<o:p></o:p>
