I've applied the various\nchanges that were suggested - so thanks very much for those. The only\nsignificant alteration is in the final patch where I had previously\nadded a command-line option to qcam to allow a digital zoom to be\nrequested. This feature has been moved to cam instead... do we think\nit's useful there?\n\nOne last question. That example application code that I wrote in a\nprevious message - I wonder if we should try and include it in\ndocumentation somewhere? And if so, do we have a natural home for it?\n\nI hope that all makes sense!\n\nThanks and best regards\nDavid\n\nDavid Plowman (6):\n libcamera: Add SensorOutputSize property\n libcamera: Initialise the SensorOutputSize property\n libcamera: Add IspCrop control\n libcamera: Add geometry helper functions\n libcamera: pipeline: raspberrypi: Implementation of digital zoom\n cam: Add command line option to test IspCrop control\n\n include/libcamera/geometry.h | 20 +++\n include/libcamera/ipa/raspberrypi.h | 1 +\n src/cam/capture.cpp | 25 +++-\n src/cam/capture.h | 2 +-\n src/cam/main.cpp | 3 +\n src/cam/main.h | 1 +\n src/ipa/raspberrypi/raspberrypi.cpp | 7 +\n src/libcamera/camera_sensor.cpp | 6 +\n src/libcamera/control_ids.yaml | 9 ++\n src/libcamera/geometry.cpp | 129 ++++++++++++++++++\n .../pipeline/raspberrypi/raspberrypi.cpp | 47 +++++++\n src/libcamera/property_ids.yaml | 19 +++\n 12 files changed, 266 insertions(+), 3 deletions(-)"}
