If I understand it correctly: your plane info can be derived from
int di = nativeView.istep();
int dj = nativeView.jstep();
int dp = nativeView.planestep();
E.g., if di=6 and dp=2 (and assuming 3 planes), you would have your 3x2 bytes per pixel contiguously,
while with di=2 you have the 16-bit values for one plane and one image row physically next to each other.
