Inputting image data to PDF with iText

I have an ImageButton in my website that has a dynamic source well it basically looks like this: "data:image/svg+xml;base64,...."

So I am trying to insert an image in to PDF using that. This is the code I use

iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(new Uri(((ImageButton) FindControl(fieldKey)).ImageUrl));

I either get a "The URI is empty" error or a path not found.

Any ideas how to approach this?

I doubt anyone would google this but I figured it out so why not post an anwser.

To implement data img types in to PDF remove the prefix part and then convert it back from base 64 in to array byte.

string theSource = ((ImageButton)FindControl(fieldKey)).ImageUrl.Replace("data:image/png;base64,", "");
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(Convert.FromBase64String(theSource));
