Hi Whiletrue,
Regarding the text color, please try using this latest version from our BugFixes page or NuGet.
We have added the PdfSignatureAppearance.FontColor
property, you can use it like this:
PdfSignatureField signatureField = ...
// Get signature appearance settings.
PdfSignatureAppearance signatureAppearance = signatureField.Appearance;
// Set font family to "Times New Roman".
signatureAppearance.FontFamily = new PdfFontFamily("Times New Roman");
// Set font color to red.
signatureAppearance.FontColor = PdfColor.FromRgb(1, 0, 0);
// ...
Regarding the signature image, GemBox.Pdf currently doesn’t provide an easy-to-use API for adding images.
But note that we’re working on this, this feature should be available in the near future (within a month or two).
For now as a workaround, I could provide you a solution that uses GemBox.Document to create any kind of visual appearance that you want (both text and image) which you would then add to a signature field using GemBox.Pdf.
Let me know if you’re interested in this.
Regards,
Mario
