     \property QQuickItem::smooth
-    \brief whether the item is smoothly transformed.
+    \brief whether the item is smoothed or not.
 
-    This property is provided purely for the purpose of optimization. Turning
-    smooth transforms off is faster, but looks worse; turning smooth
-    transformations on is slower, but looks better.
+    Primarily used in image based elements to decide if the item should use smooth
+    sampling or not. Smooth sampling is performed using linear interpolation, while
+    non-smooth is performed using nearest neighbor.
 
-    By default smooth transformations are off.
+    In Qt Quick 2.0, this property has minimal impact on performance.
+
+    By default is true.
