I'm succesffully signing documents with multiples signatures. In all of them I set a company logo at the left of the "signature.Bounds" (a PNG file) and a graphic text at the right. The signature is visible and seems like a "stamp" in PDF.
Everytime I add a new signature to the same PDF, its logo is set and shown normally but the logo of any pre-existent signature disappears. Interesting to notice that all signature's graphic text remains correctly untouchable; only the logo is deleted.
I mean, if I have a signature with LOGO and TEXT in a PDF, adding a new signature to it erases only the logo of this older signature!
I'm using the default commands:
g = signature.Appearance.Normal.Graphics
g.DrawImage(bmp, New PointF(0, 0), ImageSize)
loadedDocument.Pages(0).Graphics.DrawString("Serial: " & Serial(1), Font, Pen, Brush, x, y)
Does anyone have any idea about why it is happening?
I appreciate any help.
