Hello,
I have been following your advice and I reach my first goal.
I understand from JordiCP (Crop CameraExPreview) that the preview data comes in the original camera orientation and CameraEx applies some orientation transformations to the displayed image. I have been obliged to apply opposite transformation to display the delayed pictures buffered. But the calculations slowed the frame rate down too much. So i just rotate the imageview (SetPivotX, SetPivotY and SetRotation).
I have set the zoom parameter by code but this one is centered and it seems not easy to get the maxZoom value on a zone of interest different from the center.
Do you have any other advice to reach to zoom on another focus point that the centre of the picture of the camera's video stream.
I found the JSTouchImageView librairy, but maybe I should use another method?
Thanks for your advices.
Olivier
