| | How to get the bitmap image of a control Hi all How to retrieve the bitmap image of a given WPF control (or visualtree) ? I'd like to be able to insert a kind of control "screen copy" in an arbitrary destination (a Word document for instance). Is there an easy way to do that ? I think I've seen that somewhere but I can't remember where. Thanx in advance. |

And I can't figure what I'im doing wrong. Here is my code (vb sorry )Public Function GetImageFromVisual(ByVal Target As Visual, ByVal width As Integer, ByVal height As Integer) As RenderTargetBitmap Dim bounds As Rect = VisualTreeHelper.GetDescendantBounds(Target) Dim renderBitmap As New RenderTargetBitmap(width, height, 96, 96, PixelFormats.Pbgra32) Dim visual As New DrawingVisual() Dim context As DrawingContext = visual.RenderOpen With context Dim brush As New VisualBrush(Target) context.DrawRectangle(brush, Nothing, New Rect(New Point(), bounds.Size)) End With renderBitmap.Render(visual) Return renderBitmap End Function If ever you can see something... Thanx in advance |

| | Re: How to get the bitmap image of a control Salut, I don't have time to debug it, but I can send you a working example per email if you want, and you can build on that. My example will be in C# though :-( Let me know Greetings, Laurent Patrice wrote: Quote: > On 31 oct, 23:32, Patrice <contact-on...@xxxxxx-si.com> wrote: Quote: >> On 31 oct, 23:25, "Laurent Bugnion, MVP" <galasoft...@xxxxxx> >> wrote: >> >> >> >> >> Quote: >>> Hi, >>> Patrice wrote: >>>> Hi all >>>> How to retrieve the bitmap image of a given WPF control (or >>>> visualtree) ? >>>> I'd like to be able to insert a kind of control "screen copy" in an >>>> arbitrary destination (a Word document for instance).
