CalibratedSpaceName | Choose a valid non-qualified name for the calibrated coordinate space that will be attached to the coordinate space tree of the output image.
SpaceToOutput | Choose whether the selected space of the output image will be a fully-qualified copy of the calibrated space name, or a fully-qualified copy of the uncalibrated space name.
UnfilledPelValue UnfilledPelValueEnabled UnfilledPelPlane0Value UnfilledPelPlane1Value UnfilledPelPlane2Value | Select the value for unfilled pixels in the output image after the tool performs an image warping.
