Hi All,

I would like to ask you a query regarding Apose.Pdf.Net. My requirement is to add a “multiline transparent textbox” over PDF page. For more explanation you can see attached sample PDF.

Any help is highly anticipated.

Thanks in advance.

Regards,

Ashish

Hi Ashish,

Thanks for your interest in our products.

In order to fulfill your requirements, you may consider adding TextStamp to the pages of an existing PDF file. Please try using the following code snippet to accomplish your requirement.

C#

//open document
PdfFileStamp fileStamp = new PdfFileStamp();
fileStamp.BindPdf("c:/pdftest/test_pdf.pdf");

//Instantiate a stamp object
Aspose.Pdf.Facades.Stamp logoStamp = new Aspose.Pdf.Facades.Stamp();
logoStamp.Opacity = 0.5f;
logoStamp.SetOrigin(100, 100);

//Instantiate an object of FormattedText class
FormattedText formatText = new FormattedText("Hello World!", System.Drawing.Color.FromArgb(180, 0, 0), Aspose.Pdf.Facades.FontStyle.TimesItalic, EncodingType.Winansi, false, 50);

//Add another line for Stamp
formatText.AddNewLineText("Good Luck");

//BindLogo to PDF
logoStamp.BindLogo(formatText);

//add stamp to PDF file
fileStamp.AddStamp(logoStamp);

// save stamped PDF file
fileStamp.Save("c:/pdftest/MultiLineStamp.pdf");

Hi Nayyer,

First of all thanks for the response and the code provided by you.

I am afraid to say that you did not get it correctly as my requirement is different from the output produced by code provided by you.

Let me explain my requirement once again. I need to add a transparent (say opacity 30%) rectangle on any certain location. Then we need to add multiline text over the transparent box, however our text will not be transparent. Please see again the attached pdf in my first post.

Please let me know if you need further clarification.

Thanks in advance.

Regards,
Ashish
