[libcamera-devel] [PATCH v2 0/6] Digital zoom

[David Plowman]

Hi everyone

Here's version 2 of the digital zoom patches. I've applied the various
changes that were suggested - so thanks very much for those. The only
significant alteration is in the final patch where I had previously
added a command-line option to qcam to allow a digital zoom to be
requested. This feature has been moved to cam instead... do we think
it's useful there?

One last question. That example application code that I wrote in a
previous message - I wonder if we should try and include it in
documentation somewhere? And if so, do we have a natural home for it?

I hope that all makes sense!

Thanks and best regards
David
