Hello,

Thanks for your letter.
You could refer to below code snippet to achieve your requirement, If there is any question, just feel free to write back.

Code: Select all

//input x coordinate
Console.WriteLine("Please input x coordinate:");
float x = Convert.ToSingle(Console.ReadLine());
//input y coordinate
Console.WriteLine("Please input y coordinate:");
float y = Convert.ToSingle(Console.ReadLine());
//Check if there is text content in the rectangle
string text = doc.Pages[0].ExtractText(new RectangleF(x, y, 100, 100));
if (text == "")
{
     //Sign signature in the rectangle
     ...
}
else
Console.WriteLine("overlap with text!");

Hello,

Thanks for the response.
will this code works if there is already a signature in that particular location.

Does ExtractText method extracts existing digital signature as text?

Hello,

Thanks for the response,
Is it possible to show green tick mark on digital signature using spire.pdf.
We have used signature image property but it is hiding issuer name.

We need to show green tick mark in the middle of the digital signature with issuer name.
