/**
- * Enable/Disable AutoPadding for Vec3 Elements.
+ * Specifies the mapping between the Allocation's cells and an array's elements
+ * when data is copied from the Allocation to the array, or vice-versa.
*
- * <p> Vec3 Elements, such as {@link Element#U8_3} are treated as Vec4 Elements
- * with the fourth vector element used as padding. Enabling the AutoPadding feature
- * will automatically add/remove the padding when you copy to/from an Allocation
- * with a Vec3 Element.
- * <p> By default: Disabled.
+ * Only applies to an Allocation whose Element is a vector of length 3 (such as
+ * {@link Element#U8_3} or {@link Element#RGB_888}). Enabling this feature may make
+ * copying data from the Allocation to an array or vice-versa less efficient.
+ *
+ * <p> Vec3 Element cells are stored in an Allocation as Vec4 Element cells with
+ * the same {@link android.renderscript.Element.DataType}, with the fourth vector
+ * component treated as padding. When this feature is enabled, only the data components,
+ * i.e. the first 3 vector components of each cell, will be mapped between the array
+ * and the Allocation. When disabled, explicit mapping of the padding components
+ * is required, as described in the following example.
+ *
+ * <p> For example, when copying an integer array to an Allocation of two {@link
+ * Element#I32_3} cells using {@link #copyFrom(int[])}:
+ * <p> When disabled:
+ * The array must have at least 8 integers, with the first 4 integers copied
+ * to the first cell of the Allocation, and the next 4 integers copied to
+ * the second cell. The 4th and 8th integers are mapped as the padding components.
+ *
+ * <p> When enabled:
+ * The array just needs to have at least 6 integers, with the first 3 integers
+ * copied to the the first cell as data components, and the next 3 copied to
+ * the second cell. There is no mapping for the padding components.
+ *
+ * <p> Similarly, when copying a byte array to an Allocation of two {@link
+ * Element#I32_3} cells, using {@link #copyFromUnchecked(int[])}:
+ * <p> When disabled:
+ * The array must have at least 32 bytes, with the first 16 bytes copied
+ * to the first cell of the Allocation, and the next 16 bytes copied to
+ * the second cell. The 13th-16th and 29th-32nd bytes are mapped as padding
+ * components.
+ *
+ * <p> When enabled:
+ * The array just needs to have at least 24 bytes, with the first 12 bytes copied
+ * to the first cell of the Allocation, and the next 12 bytes copied to
+ * the second cell. There is no mapping for the padding components.
+ *
+ * <p> Similar to copying data to an Allocation from an array, when copying data from an
+ * Allocation to an array, the padding components for Vec3 Element cells will not be
+ * copied/mapped to the array if AutoPadding is enabled.
+ *
+ * <p> Default: Disabled.
*
* @param useAutoPadding True: enable AutoPadding; False: disable AutoPadding
