Data buffers

This chapter discusses data buffers in detail. It shows you how to allocate and manage data buffers, and how to restrict an operation to a portion of a data buffer using child buffers and regions of interest. It shows you how YUV buffers are stored, how to create a user-defined buffer, and how Aurora Imaging Library defines the pixel reference position. It shows you how to grab images with a Bayer camera and restore the color information.
