This will require a custom image processing library that supports image tilling and a way to implement custom image viewer that is not based on Gtk.Picture.

libvips looks like a good contender and it appears to support tilling (required to zoom on images without going OOM).
There is a complete image viewer made using vips, which could be useful to see how the zoom is implemented here.

Disregard what's written above. This can be achieved by subclassing Gdk.Texture. There are examples available in GTK4 Demo, Tuba and Extension Manager.
