Android Question webview.CaptureBitmap.WriteToStream - help needed

[Zeev Goldstein]

hi

i'm trying to save a webview content as image using this

Dim out As OutputStream
    out.InitializeToBytesArray(1000)
    out =  File.OpenOutput(File.DirInternal, "image.jpg",False)
    Text_WebView.CaptureBitmap.WriteToStream(out,100,"JPG")
    out.Close

with or without Erel's following code called as he said from activity_create

Sub EnableSlowWebViewDocumentDraw
    Dim p As Phone
    If p.SdkVersion >= 21 Then
        Dim jo As JavaObject
        jo.InitializeStatic("android.webkit.WebView").RunMethod("enableSlowWholeDocumentDraw", Null)
    End If
End Sub

i get the following error (on the bold line in my code)
java.lang.IllegalArgumentException: No enum constant android.graphics.Bitmap.CompressFormat.JPG

problem solved using this correction

Dim out As OutputStream
    out = File.OpenOutput(File.Dirinternal, "image.png", False)
    Text_WebView.CaptureBitmap.WriteToStream(out, 100, "PNG")
    out.Close
