[HOW-TO] Add new Scaler crops

[rahulc29]

The only scaler crop that seems to work is 64x64. If I try to change the scaler crop, nothing happens. The only scaler crops that are shown by the metadata is (0,0,64,64). I have a Camera Module 2 IMX219 and libcamera-apps works just fine (at full resolution). However, picamera2 does not allow me to change the scaler crop. Any help/pointers appreciated.

Hi, and thanks for the question. I'm afraid I wasn't quite sure what you were wanting to do, or what you had tried. Might you be able to attach a short self-contained test script (just a few lines, preferably) that shows what is not working as you expect? Thanks!
