[RESOLVED] Save screenshot as jpeg

Hello, I'm using the below code to capture desktop screenshot, it is working but doesn’t encode the screenshot result in real jpeg, I came to know that from the huge size of the saved jpeg file around 5MB!!!

Can anyone please help in fixing this issue?

Code:

---

           
Dim ScreenSize As Size = New Size(My.Computer.Screen.Bounds.Width, My.Computer.Screen.Bounds.Height)
            Dim screenGrab As New Bitmap(My.Computer.Screen.Bounds.Width, My.Computer.Screen.Bounds.Height)
            Dim g As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(screenGrab)
            g.CopyFromScreen(New Point(0, 0), New Point(0, 0), ScreenSize)

            screenGrab.Save("C:\Screenshot.jpeg")

---

Well obviously its not going to work:

Code:

---

Dim screenGrab As New Bitmap(My.Computer.Screen.Bounds.Width, My.Computer.Screen.Bounds.Height)

You're creating a new Bitmap
I once heard a quote: "You can put a Tuxedo on a goat, but it's still a goat."
Basically, you can save a file as a jpeg, but if you create it as a bitmap, it's still a bitmap.

The Save method is overloaded. You can specify the file format as well as the path. Let Intellisense guide you. Put the cursor at the end of that line and hit Backspace and Intellisense should popup and provide you with your options. If it doesn't then just hit Ctrl+Space.

Code:

Private Sub SaveImage()
        Dim BMPname As String
        Dim graph As Graphics = Nothing
        Try
            Dim bmp As Bitmap = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height)
            graph = Graphics.FromImage(bmp)
            graph.CopyFromScreen(0, 0, 0, 0, bmp.Size)
           
            BMPname = "C:\Screenshot.jpeg"

            bmp.Save(BMPname,System.Drawing.Imaging.ImageFormat.Jpeg)

        Finally
            graph.Dispose()
        End Try
    End Sub

Thank you Smartacus :)
