Turn off the work of a scatter when the mouse is outside of visible part of the object

[me2 beats]

what is a good way to avoid such a behavior of the scatter (see attached gif)?

I mean I don't want the scatter to let me do scaling/translation/rotation outside the visible part of the image, that is, to move the image only when the mouse is inside the circle.

Scatter:
    size: root.size
    Image:
        source: 'data/logo/kivy-icon-512.png'
        size: self.parent.size
        allow_stretch: True

I understand scatter is a rectangle and it can not be made in any other shape.
but I think there is a way to check if the mouse is on a colored or transparent pixel of the png image and if the pixel under the mouse is transparent, that is, we do not see the color here, then we set do_scale and do_translation = 0
