# 3.5 Other `nip2` features useful for reflectograms

You can use `nip2`'s general image processing facilities to play around with reflectogram mosaics. You can make false-colour images of your reflectograms, blend them with visible images or X-rays, search them for edges, and so on see `$VIPSHOME/share/nip2/data/examples/registering/registering.ws` and `$VIPSHOME/share/nip2/data/examples/overlays_and_blending/overlay_blend.ws` for some examples.

There are also some first order mosaic functions: `Tasks` / `Mosaic` / `Two Points` / `Left to Right` and `Tasks` / `Mosaic` / `Two Points` / `Top to Bottom`. These functions automatically rotate and scale the right-hand image in a join. They are useful for assembling X-ray mosaics, and for fixing very difficult joins in reflectogram images. These functions work the same way as the `One Point` functions except that you will need to define two tie-points on each image.

You can mosaic images of any numeric type: 16-bit integer images are handy for mosaicing X-ray images, for example.
