Urwid ueberzogen provides widgets which allows to easily use ueberzug with urwid.

urwid-ueberzogen

The source code contains a more detailed documentation.

Positions are calculated relative to this widget
which means that urwid_ueberzogen.Container has to be the root widget
in order to calculate the absolute position.

To make it easier to work with placements
changes are only transmitted on redrawing the urwid layout.
This also means that for example calling the hide function
of this class won't do anything till urwid redraws the screen.
If you want to see changes immediately you have to use it the following way:

with canvas.lazy_drawing:
    image_container.hide()

Puts an image placement above an urwid widget.
