Detailed Description

Raw image interface.

To use this interface, you need to inherit it and create your own implementation for a specific image type. See an example of implementation in face_sdk_3divi/example/cv_raw_image.py.

WARNING: Member functions RawImage.data, RawImage.width, RawImage.height and RawImage.format can't throw any exceptions, since they will be called from the dynamic library and throwing an exception can cause a crash.
So instead of throwing an exception you can return some invalid values:

• NULL pointer - from the RawImage.data,
• non-positive number - from the RawImage.width and RawImage.height,
• negative number - from the RawImage.format.
  The facerec library will handle incorrect data and will throw a Error exception object that you will be able to catch.
