[NTG-context] Full page figure

Hello everybody in list. I have drawn title page for my book on paper, later scanned it. And now I want to add it to my book as a first page. But there is the a problem. When I place it as a figure it is too large to fit on page. I have discovered [size=fit] argument, but this places it inside the page and margins remains. So how can I place this title page without margins? (A4 scanned page to A4 PDF page) I have scan in two formats PNG and PDF (A4 paper size). Regards -- Mikoláš Štrajt
