The window method from the Image class do not take the offset into account

[bathienle]

In my simple application, I use SLDC to segment a grayscale image based on a threshold.
Since my image is very large (1.5GB), I have tested the application on a window of the image using the window function.
At the end of the workflow, when I visualize the polygons on the image, they are located at the origin of the image and not at the position of the window.
