so i load a gif onto a canvas and when i click the canvs i want to get
the color of the pixel that is clicked.
so i need to ge the object im clicking.
i was told in another thread to use find_withtag or find_closest but
it is not working, maybe im using the
method on the wrong object.
how do i do this?
and how do i then get specifics about that object, ie the pixel-color?
