I need to rotate a WriteableBitmap and scale it down or up before it gets cropped. My current code will rotate but will crop the edges if the height is larger then the width. I assume I need to scale? public WriteableBitmap Rotate(WriteableBitmap Source, double Angle) { RotateTransform rt = new RotateTransform(); rt.Angle = Angle; TransformGroup transform = new TransformGroup(); transform.Children.Add(rt); Image tempImage2 = new Image(); WriteableBitmap wb; rt.CenterX = Source.PixelWidth / 2; rt.CenterY = Source.PixelHeight / 2; tempImage2.Width = Source.PixelWidth; tempImage2.Height = Source.PixelHeight; wb = new WriteableBitmap((int)(Source.PixelWidth), Source.PixelHeight); tempImage2.Source = Source; tempImage2.UpdateLayout(); wb.Render(tempImage2, transform); wb.Invalidate(); return wb; } How do I scale down the image so it will not be cropped? Or is there another way?
