+    \qmlproperty bool BlendedImage::smooth
+
+    Set this property if you want the image to be smoothly filtered when scaled or
+    transformed.  Smooth filtering gives better visual quality, but is slower.  If
+    the BlendedImage is displayed at its natural size, this property has no visual or
+    performance effect.
+
+    \note Generally scaling artifacts are only visible if the image is stationary on
+    the screen.  A common pattern when animating an image is to disable smooth
+    filtering at the beginning of the animation and reenable it at the conclusion.
