Color value of an existing pixel

[mario51t]

I need to know the color value of a pixel in an existing jpg image. I did not find any solution in the .NET class library. While I have found two third party packages that claim to be able to do it, I'd like to avoid adding DLLs if possible. Anyone knows of a way to do this within VB.NET?

TIA, /Mario

Yes.. it is possible...
Look over the following code snip. It is used to capture the pixle color when the mouse is clicked on a spot in a picturebox.. (I was using it to select a transpancy color for a bitmap...)


Have fun

    Private Sub pBox1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles pBox1.MouseUp
        If Not pBox1.Image Is Nothing Then
            Dim bmp As New Bitmap(pBox1.Image)
            Try
                PictureBox1.BackColor = bmp.GetPixel(e.X, e.Y)
            Catch
            End Try
        End If
    End Sub
