[RESOLVED] [2005] Image Overlay

If I have two images and I want to overlay them. How would I do that?

Example:

Image 1:
http://radar.weather.gov/ridge/Overl...Topo_Short.jpg

Image 2:
http://radar.weather.gov/ridge/Overl...ounty_Long.gif

How would I take image 2 and overlay it over image 1?

Do it in photoshop maybe?... Just kidding :) Sorry I don't have the answer for you.

Try this link

I'm not quite understanding the information in that link. That is dealing with the Form1_Paint event. I need this to happen outside of that event.

I have a treeview control with a list of all the states and their radar id's.

Here is the code.

Code:

---

    Private Sub cmdRadar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRadar.Click
        Dim TopoString As String
        Dim CountyString As String
        Dim Request As HttpWebRequest
        Dim Response As WebResponse
        Dim str As IO.Stream

        lblStatus.Text = "Requesting Topo Image"
        StatusStrip1.Refresh()
        TopoString = "http://radar.weather.gov/ridge/Overlays/Topo/Short/" & GetRadarID(tvRadarID.SelectedNode.Text) & "_Topo_Short.jpg"
        Request = WebRequest.Create(TopoString)
        Response = Request.GetResponse()
        str = Response.GetResponseStream
        Dim Topo_Pic As New Bitmap(str)
        lblStatus.Text = "Topo Image Received"
        StatusStrip1.Refresh()

        lblStatus.Text = "Requesting County Image"
        StatusStrip1.Refresh()
        CountyString = "http://radar.weather.gov/ridge/Overlays/County/Long/" & GetRadarID(tvRadarID.SelectedNode.Text) & "_County_Long.gif"
        Request = WebRequest.Create(CountyString)
        Response = Request.GetResponse()
        str = Response.GetResponseStream
        Dim County_Pic As New Bitmap(str)
        lblStatus.Text = "County Image Received"
        StatusStrip1.Refresh()

        PictureBox1.Image = (Topo_Pic)
    End Sub

    Private Function GetRadarID(ByVal TreeViewNodeText As String)
        Try
            Dim tmpVar As Integer
            Dim ParsedID As String
            tmpVar = Strings.InStr(TreeViewNodeText, "-")
            ParsedID = Strings.Mid(TreeViewNodeText, 1, tmpVar - 2)
            Return ParsedID
        Catch ex As Exception
            Return 0
        End Try
    End Function

When you click the button I need to to overlay the County Image on top of the Topo image...

This is going to be difficult since everytime you need to redraw the picture nothing will happen.

There is no way to overlay the two images and then display them in a picturebox?
