I have two bitmapviewer, one with the Rectanglerubberband control on it and another is to display the area highlighted by the Rectanglerubberband control. My problem is I don't know the right way to display the selected area. I am using the following code but I assume it will be slow as I need to reload the original image from file each time, then crop the image according to the Rectanglerubberband. Code:
bmvEdit.Bitmap.Load(ImageName)
bmvOriginal.Bitmap.Load(ImageName)
RectangleRubberband1.Connect(bmvOriginal)
Private Sub RectangleRubberband1_RectangleChanged(ByVal sender As Object, ByVal e As Aurigma.GraphicsMill.WinControls.RectangleEventArgs) Handles RectangleRubberband1.RectangleChanged
RectangleRubberband1.ResizeMode = WinControls.ResizeMode.Proportional
If Not RectangleRubberband1.Rectangle = Nothing Then
bmvEdit.Bitmap.Load(ImageName)
Dim Transform As BitmapTransform
Transform = New Crop(RectangleRubberband1.Rectangle)
Transform.ApplyTransform(bmvEdit.Bitmap)
End If
End Sub
There has to be a more resource friendly way to do this. Edited by user Wednesday, December 19, 2007 3:18:43 PM(UTC)

Hello, Yes, there is more resource-friendly way. You have no need to reload the original image from file every time (loading from file is a time-consuming operation). It will be faster to use already loaded bitmap from the first BitmapViewer control. Here is small code snippet which illustrates the way: Code: bmvOriginal.Bitmap.Load("Y:\MultiLayerViewer\lexus.jpg")
bmvEdit.Bitmap = CType(bmvOriginal.Bitmap.Clone(), Aurigma.GraphicsMill.Bitmap)
Private Sub RectangleRubberband1_RectangleChanged(ByVal sender As Object, ByVal e As Aurigma.GraphicsMill.WinControls.RectangleEventArgs) Handles RectangleRubberband1.RectangleChanged
RectangleRubberband1.ResizeMode = WinControls.ResizeMode.Proportional
If Not RectangleRubberband1.Rectangle.IsEmpty Then
Dim cropTransform As Aurigma.GraphicsMill.Transforms.Crop
cropTransform = New Aurigma.GraphicsMill.Transforms.Crop(RectangleRubberband1.Rectangle)
cropTransform.ApplyTransform(bmvOriginal.Bitmap, bmvEdit.Bitmap)
End If
End Sub
