WebPicture has an Operator_Convert method which will turn itself from/into a Picture. Both the following syntaxes are legal:

Dim p As Picture = MyWebPicture
Dim wp As WebPicture = p

Converting Picture to WebPicture gives you a PNG encoded image. For better performance avoid converting from WebPicture to Picture in your application and keep original Picture object.

Unlike WebFile, WebPicture defaults the session property to the session which it was created in.


Convert a Picture, created at runtime to a WebPicture to display using a WebImageView:

Dim p As New Picture(100, 100, 32)
p.Graphics.ForeColor = &c0000ff // Blue
p.Graphics.FillRect(10, 10, 50, 50)

Dim wp As WebPicture = p
ImageView1.Picture = wp
