Can you please provide more details about the code you are using to add the signature and the specific issue you are encountering with the vertical signature?

we are using following code.

for (int PageCnt = 1; PageCnt <= NumberofPageInFile; PageCnt++)
    {
        double xpos = 0, ypos = 0; int pageNumber = 0;
        string[] RectPos = strlist[0].Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
        pageNumber = Convert.ToInt32(RectPos[0]);
        xpos = Convert.ToDouble(RectPos[1]);
        ypos = Convert.ToDouble(RectPos[2]);
 
        PageSize size = pEdit.GetPageSize(PageCnt);
 
        ypos = GetYPosition(size.Height, ypos);
        xpos = GetXPosition(size.Width, xpos);
 
        if (size.Height > pEdit.GetPageSize(1).Height)
        {
            if (Convert.ToDouble(RectPos[2]) <= 100)
            {
 
                ypos = ypos + (size.Height - pEdit.GetPageSize(1).Height);
            }
 
            ypos = ypos - (size.Height - pEdit.GetPageSize(1).Height);
 
            if (ypos < 0)
            {
                ypos = System.Math.Abs(ypos);
            }
        }
        else if (size.Height < pEdit.GetPageSize(1).Height)
        {
            if (Convert.ToDouble(RectPos[2]) <= 100)
            {
 
                ypos = ypos + (pEdit.GetPageSize(1).Height - size.Height);
            }
 
            ypos = (pEdit.GetPageSize(1).Height - size.Height - ypos);
 
            if (ypos < 0)
            {
                ypos = System.Math.Abs(Convert.ToDouble(ypos));
            }
        }
 
        System.Drawing.Rectangle rect = new System.Drawing.Rectangle(Convert.ToInt32(xpos) + 10, Convert.ToInt32(ypos + 5), 150, 40);
 
 
        using (MemoryStream ms = new MemoryStream())
        {
            bitMapImage.Save(ms, ImageFormat.Png);
 
            pdfSign.SignatureAppearanceStream = ms;
            pdfSign.BindPdf(Destination);
            pdfSign.Sign(PageCnt, true, rect, signature);
            pdfSign.Save(Destination);
        }
    }

We tried to use your code snippet but it was giving runtime errors. Can you please share complete sample code (minimal) that can be used to replicate the issue? We will further proceed to assist you accordingly.

Its difficult to send whole code as its application size is big. Attaching the pdf file where we get the signature vertically. Please try signing on the attached file.

Looks like the pages inside PDF document are rotated on an angle due to which the signatures are being added vertically.
