Update

- 08.15.2007 - user defined image formats, save path, base file name, text overlay/watermark, and screen res guidelines... and some other ideas to implement.

Introduction

I have seen other articles that describe how to accomplish this, but had no luck in getting any to work with Internet Explorer 7. This is a simple example that captures a webpage, inlcuding elements below the fold, and saves it as an image. Here is what to expect:

^{Note that this has been resized, captured images are actual size.}

Using the code

This example includes only the basics. Images are saved as PNG's in the same directory as the exe. Saving as a different image format, variable pausing, and given filename should be relatively easy to add.

Private Sub GetImage()
    If WebBrowser1.Document Is Nothing Then
        Return
    End If
    Try
        Dim scrollWidth As Integer
        Dim scrollHeight As Integer
        scrollHeight = WebBrowser1.Document.Body.ScrollRectangle.Height
        scrollWidth = WebBrowser1.Document.Body.ScrollRectangle.Width
        WebBrowser1.Size = New Size(scrollWidth, scrollHeight)
        Dim bm As New Bitmap(scrollWidth, scrollHeight)
        WebBrowser1.DrawToBitmap(bm, New Rectangle(0, 0, bm.Width, bm.Height))
        Dim SaveAsName As String
        SaveAsName = Regex.Replace(textWebURL.Text, "(\\|\/|\:|\*|\?|\""|\<|\>|\|)?", "")
        bm.Save(SaveAsName & ".png", System.Drawing.Imaging.ImageFormat.Png)
        bm.Dispose()
    Catch ex As Exception
        MessageBox.Show(ex.Message, "Exception", MessageBoxButtons.OK, MessageBoxIcon.Error)
    Finally
        '
    End Try
    buttonCapture.Enabled = True
End Sub

Points of Interest

Waiting a second or two after the document has loaded will allow that much more of the client-side animation / js / etc. to be captured. If the web page is saved as a "white" image, try the above.
