Thanks TongMuan, that's all great information and most appreciated.
I have been reluctant to update my devices from Anna to Belle in case of binary compatibilities.
I would be very interested in your pureview article as I am keenly awaiting that device to check out the camera. I would expect a new SDK or at least API is required to access the new functionality ? eg select between oversampling or raw pixels, etc.
You are quite right about the jpeg quality setting. I was mistaken that it was in advanced settings as it was in fact in ecam.h and part of CCamera. I was calling it from the camerawrapper via the provided pointer but I eventually discovered this was the problem. Here is the code (out of context)...
However, when I did this, it did work;
iCamera = iCameraWrapper->Camera();
Yes I will consider absorbing the cammerawrappercode - it was just a good starting point. Thanks for the link.
IMPORT_C CCamera* Camera();
