If you choose to ReSample, specify either DownSample or SubSample from
the pull-down menu. The default setting is DownSample .
Downsampling decreases the number of pixels in the image. Each pixel it
places has the average value of all the pixels it replaces.
Subsampling chooses a pixel in the center of the sample area and replaces
the entire area with that pixel at the specified resolution.
