we used till now this code in order to add signiture to our html:

EO.Pdf.HtmlElement input = htmlResult.HtmlDocument.GetElementById(htmlTxtId);
var txt = new AcmTextBox();
txt.Style.OffsetX = input.Location.X;
txt.Style.OffsetY = input.Location.Y;
txt.Style.Height = input.Size.Height;
txt.Style.Width = input.Size.Width;
txt.Name = pdfTxtName;
AcmPageLayout layout = new AcmPageLayout(new AcmPadding(0, 0, 0, 0));
AcmRender render = new AcmRender(input.Location.Page, 0, new AcmPageLayout(new AcmPadding(0, 0, 0, 0)));
render.Render(txt);

this doesnt do the trick any more. do we have any other option to add a signature?
the last row in the code throws execption:

at EO.Internal.bar.m()
at EO.Internal.bar.a(PdfColor A_0)
at EO.Pdf.PdfField.set_Color(PdfColor value)
at EO.Pdf.Acm.AcmField.e(gw A_0)
at EO.Pdf.Acm.AcmContent.e(gw A_0)
at EO.Pdf.Acm.AcmRender.a(AcmBlock A_0, Int32 A_1)
at EO.Pdf.Acm.AcmRender.a(Int32 A_0, AcmContent[] A_1)
at Formally.AddSignatureToPdf(HtmlToPdfResult htmlResult, String htmlTxtId, String pdfTxtName, ...) in ...


please give us a solution to our problem.

thanks in advance
