+    \inherits QtObject
+
+    \brief Maps a numerical range to another range, so that the output value
+    of the second range follows that of the original range.
+
+    The minimum and maximum input and output values are specified as values of
+    the \l inputMinimum, \l inputMaximum, \l outputMinimum, and \l outputMaximum properties.
+    The original value is specified as the value of the \l output property.
+
+    For example, if you map input in the range of \c {-1,1} to output in the
+    range of \c {0,1000}, and the original value changes from -1 to 1, the
+    output value will change from 0 to 1000. This is useful when remapping
+    the current frame on the timeline, for example.
+
+    Designers can use the Range Mapper type in \QDS instead of writing
+    JavaScript expressions.
+
+    \section1 Example Usage
+
+    In the following example, we use a RangeMapper type to map the value range
+    from -1 to 1 that is specified for a \l Slider type to a range from 10 to
+    1000:
+
+    \code
+    Rectangle {
+        Slider {
+            id: slider
+            from: -1
+            to: 1
+            value: -1
+        }
+        RangeMapper {
+            id: rangeMapper
+            outputMinimum: 10
+            outputMaximum: 1000
+            inputMinimum: slider.from
+            inputMaximum: slider.to
+            input: slider.value
+        }
+    }
+    \endcode
