Message : I've tried to put a watermark behind the text with Aspose.Pdf
But it is printed always over the text.
How could I accomplished this?
I don't mind if it's made with text or image watermark.
Thanks for the attention.

Hi,

This is a knows issue and we have logged it. As a workaround please refer to the example code at Send watermark to back.

#3

I’ve tried the workaround, but it doesn’t work.

Text textBorrador = new Text(“Ahórcame”);
textBorrador.TextInfo.FontSize = 75;
textBorrador.RotatingAngle = 45;
textBorrador.TextInfo.Color = new Aspose.Pdf.Color(System.Drawing.Color.LightGray.Name);
textBorrador.TextInfo.RenderingMode = RenderingMode.StrokeText;

Aspose.Pdf.FloatingBox fbWaterMark = new Aspose.Pdf.FloatingBox(400,200);
fbWaterMark.Left = 100;
fbWaterMark.Top = 300;
fbWaterMark.Paragraphs.Add(textBorrador);

Aspose.Pdf.Section sectionPDF = docPDF.Sections[0];
Aspose.Pdf.HeaderFooter oddHeader = sectionPDF.OddHeader;
Aspose.Pdf.HeaderFooter evenHeader = sectionPDF.EvenHeader;

oddHeader.Paragraphs.Add(fbWaterMark);
evenHeader.Paragraphs.Add(fbWaterMark);

If I use docPDF.Sections[0] I don’t see any watermark. If I use docPDF.Sections[1], I see the watermark in the second page.

Thanks for the attention.

Hi,

Can you please send us the complete code including the part where you are creating the pdf.

Thanks.

// Save pdf to memory

docPDF.Save(pdfStream);

// After this just I create a temp file with this byte array to test the result.

Hi,

Sorry for the inconvenience but we are going to need the word document as well for testing.

Thanks.

#7

No problem. Here you have the word document.

#8

Hi,

I have been able to reproduce this problem. I will discuss this with the developers and we will inform you of a solution as soon as possible.

Thanks.

#9

Hi,

Sorry for my mistake. I checked this issue again and found you can use the example code at [Custom Watermark](http://www.aspose.com/wiki/default.aspx/Aspose.Pdf/CustomWatermark.html) and and the following line:

pdf1.IsWatermarkOnTop = false;

#10

I’ve tried IsWatermarkOnTop = false, but It seems to have the same behaviour.
When I use Sections[0] I don’t see any watermark, and when using Sections[1] the watermark is showed just in the second page.

Can you reproduce the problem?

Thanks again for the attention.

#11

I haven't seen any changes in the newest version of Aspose.pdf

Were you able to reproduce the problem?

#12

I don’t know why your last message is ignored and we have not replied to you. I am terribly sorry for that. I tested with the following code and it works:

//add watermark here
Text textBorrador = new Text(“Ahórcame”);
textBorrador.TextInfo.FontSize = 75;
textBorrador.RotatingAngle = 45;
textBorrador.TextInfo.Color = new Aspose.Pdf.Color(System.Drawing.Color.LightGray.Name);
textBorrador.TextInfo.RenderingMode = RenderingMode.StrokeText;
Aspose.Pdf.FloatingBox fbWaterMark = new Aspose.Pdf.FloatingBox(400,200);
fbWaterMark.Left = 100;
fbWaterMark.Top = 300;
fbWaterMark.Paragraphs.Add(textBorrador);
pdf.Watermarks.Add(fbWaterMark);
pdf.IsWatermarkOnTop = false;

#13

GREAT!

Thanks a lot.
