+ * RAW12 is a single-channel, 12-bit per pixel, densely packed in each row,

+ * an image sensor.
+ *
+ * In an image buffer with this format, starting from the first pixel of each

+ * - a vertical stride equal to the height
+ * - strides are specified in bytes, not in pixels
+ *
+ * size = stride * height
+ *
+ * When stride is equal to width * (12 / 8), there will be no padding bytes at

+ * This format must be accepted by the gralloc module when used with the
+ * following usage flags:
