Hi Ahmet,


Thanks for your inquiry. Please share the complete code you’re using for inserting Watermark Shape before saving to PDF. I will investigate the issue on my side and provide you more information.

Best Regards,

Hi Ahmet,


Thanks for your inquiry. I feel your query is more related to Aspose.PDF, I will move your request in Aspose.PDF forum. My colleagues from Aspose.PDF component team will answer you shortly.

Alternatively, you may also try adding a watermark inside a Word document using Aspose.Words. Once the watermark is added, you can then convert this Word document to PDF format. In this case the resultant PDF will contain the watermark image. Please read the following article for more details:

Hi Ahmet,


Thanks for contacting support.

I have tested the scenario using Aspose.Pdf for .NET 7.4.0 and I am unable to notice any issue. Watermark and page contents are properly being displayed. Can you please share the source PDF file which you are using so that we can test the scenario at our end. We are sorry for this inconvenience.

Hi Nayyer,


I have rendered TL-7.5.2-188-D+STEP-LAP.doc document to Pdf format by using the latest version of Aspose.Words i.e. 11.9.0 on my side and attached the Pdf here for your reference.

Best Regards,

Hi Awais,


Thanks for sharing the document.

I have again tested the scenario and problem is also appearing when using the output generated with Aspose.Words for .NET 11.9.0. The development team will further investigate this issue and hopefully they will be able to figure out the reasons of this problem.

Hi,

Do you have any improvement?

Hi Ahmet,

Thank you for being patient.

Our development team has further looked into your issue and the following is their feedback.

Text in your file has white color areas due to which the stamp is overdrawn by text. To make the stamp visible and not overlapped by the text area, you may use Stamp.IsBackground = false to show the stamp over the text. Also set opacity to avoid hiding the stamp under the text. Please see the following updated code (Changes are marked in bold).

string kKopya = "KONTROLLU KOPYA";

if (kKopya != "") {
    int iFontSize = 36;
    System.Drawing.Color YazıRengi = System.Drawing.Color.Red;
    int iYer = 4;
    int iAci = 45;

    PdfFileInfo fileInfo = new PdfFileInfo(@"D:\TL-7.5.2-188-D+STEP-LAP.pdf");
    Aspose.Pdf.Facades.Stamp aStamp = new Aspose.Pdf.Facades.Stamp();
    kKopya = kKopya.Replace("ı", "i").Replace("İ", "I").Replace("ş", "s").Replace("Ş", "S").Replace("ğ", "g").Replace("Ğ", "G");
    FormattedText formatText = new FormattedText(
        kKopya,
        YazıRengi,
        Aspose.Pdf.Facades.FontStyle.CourierBold,
        EncodingType.Cp1252,
        false,
        iFontSize
    );

    aStamp.BindLogo(formatText);
    float vtext = formatText.TextHeight / 2, htext = formatText.TextWidth / 2;

    **aStamp.IsBackground = false;**
    **aStamp.Opacity = 0.3f;**
    aStamp.Rotation = iAci;
    float iAngel = (float)(System.Math.PI * iAci / 180.0);
    float fx = 0, fy = 0, cons = 30;

    switch (iYer) {
        case 0: fx = cons; fy = fileInfo.GetPageHeight(1) - cons; break;
        case 1: fx = fileInfo.GetPageWidth(1) / 2; fy = fileInfo.GetPageHeight(1) - cons; break;
        case 2: fx = fileInfo.GetPageWidth(1) - cons; fy = fileInfo.GetPageHeight(1) - cons; break;
        case 3: fx = cons; fy = fileInfo.GetPageHeight(1) / 2; break;
        case 4: fx = fileInfo.GetPageWidth(1) / 2; fy = fileInfo.GetPageHeight(1) / 2; break;
        case 5: fx = fileInfo.GetPageWidth(1) - cons; fy = fileInfo.GetPageHeight(1) / 2; break;
        case 6: fx = cons; fy = cons; break;
        case 7: fx = fileInfo.GetPageWidth(1) / 2; fy = cons; break;
        case 8: fx = fileInfo.GetPageWidth(1) - cons; fy = cons; break;
        default: fx = cons; fy = cons; break;
    }

    fx = (float)(fx - (System.Math.Cos(iAngel) * htext));
    fy = (float)(fy - (System.Math.Sin(iAngel) * htext));
    if (fx < 0) fx = cons;
    if (fy < 0) fy = cons;

    aStamp.SetOrigin(fx, fy);

    string outputFileName = @"D:\TL-7.5.2-188-D+STEP-LAP_Stampped.pdf";

    PdfFileStamp stamper = new PdfFileStamp(
        @"D:\TL-7.5.2-188-D+STEP-LAP.pdf",
        outputFileName
    );
    stamper.AddStamp(aStamp);
    stamper.Close();
}

Attached is the generated file for reference.

Sorry for the inconvenience,
