Hello,
I'm using the RadImageEditor control in a WPF application using the Office2013 theme.
With ScaleFactor at 0, there is a margin around the image and it is not aligned with the orther controls.
With another scale factor, the scroll bars are out by one pixel: the top of the image is one pixel lower than the vertical scroll bar and the left of the image is one pixel at the right of the horizontal scroll bar.
