▪ Sets the Start Offset and End Offset of the marquee in the first and second directions normal to the spine as a value offset from the marquee start or end (when Marquee Size method is Offset).
◦ Radial and Depth (when Radial is selected)
Radial is selected)—Exports the parameter value for editing outside of Warp.▪ Sets the Start and End of the marquee radial to the spine in one direction, and at a depth in the second, as a percentage of the original marquee (when Marquee Size method is Proportional).
▪ Sets the Start and Length of the marquee radial to the spine in one direction, and at a depth in the second, as a value (when Marquee Size method is Absolute).
