And Rotator supports the following features.
- Image crop operation support.
- Rotate operation support to 90, 180 or 270 degree.
- Flip operation support to vertical, horizontal or both.
. as limitaions, the pixel format to source buffer should be
same as the one to destination buffer and no scaler.
This driver is registered to IPP subsystem framework to be used by user side
and user can control the Rotator hardware through some interfaces of IPP
subsystem framework.
