Hi everyone,

I am facing a problem, when placing a watermark behind a PDF. I m using third method of applying the watermark i.e.

XPen pen = new XPen(XColor.FromArgb(50, 75, 0, 130), 3);
XBrush brush = new XSolidBrush(XColor.FromArgb(50, 106, 90, 205));

// Stroke the outline of the path
gfx.DrawPath(pen, brush, path);

Most of the PDFs are working fine, but few of the PDFs generated from MS Word and Adobe Professional 7 are causing problem. When I place watermark on those PDFs, the text and scanned images got dimmed even not readable.

While the same PDf works fine with the other two methods provided for watermark. But I have to use the third one which causes issue. Could anyone please help me in this issue.

Don't forget to set PDF version to 1.4 or higher.
The first parameter of FromArgb specifies the opacity of the watermark - you could try other values with higher transparency.

The third method places watermarks before (not behind) the original content of the PDF file.

Hi,

I am working on the PDF with version higher than 1.4. The version of the PDF used is 1.6.
I am still working on it and found that the problem only occurs when I want to manipulate a PDF which is generated from a PDF using adobe PDF printer.
In the third method I set option to Append instead of prepend, then why it appears before text instead of behind text.
Please let me know what fix should be done.
Thanks
