+Scale filter description:
+
+Scales image to the specified Maximum Width and Maximum Height preserving
+Aspect Ratio if necessary.
+
+
+MaximumWidth        - Set the MaximumWidth property to the width (in pixels)
+                      that you wish to scale the image to.
+MaximumHeight       - Set the MaximumHeight property to the height (in pixels)
+                      that you wish to scale the image to.
+PreserveAspectRatio - Set the PreserveAspectRatio property to True
+                      [the default] if you wish to maintain the current aspect
+                      ration of the image, otherwise False and the image will
+                      be stretched to the MaximumWidth and MaximumHeight
+FrameIndex          - Set the FrameIndex property to the index of a frame if
+                      you wish to modify a frame other than the ActiveFrame,
+                      otherwise 0 [the default]
