I need to write text, e.g. "Copyright", on top of a photograph and then save the photo with the text embedded in it to a file and/or a database.

Dim Canvas As Graphics
Dim image1 As Bitmap

Canvas = Graphics.FromImage(Photo.Image)
Dim PhotoImage As Image
PhotoImage = Photo.Image

Dim GridColor As Color = Color.White
Dim GridBrush As New SolidBrush(GridColor)
Dim GridPen As New Pen(GridColor)
Dim GridFont As New Font("Verdana", 12, FontStyle.Bold)
Canvas.DrawString("Copyright", GridFont, GridBrush, 10, 10)

' Line below causes Graphics type cannot be converted to Bitmap error
image1 = Canvas
PhotoImage = image1

' Draw image to screen.
e.Graphics.DrawImage(image1, New PointF(0.0F, 0.0F))

As you can see, I tried using a bitmap as a transitional stage between an image and a graphics object, but that didn't work. What I think I need is a ToImage method that does the opposite of the FromImage method.

Any suggestions would be gratefully received,
David.
