Hi robintao,

Sorry that you cannot create a spline to clip image boundary directly, but you can try to convert the spline line to polyline then clip.

Create a Spline then edit the spline convert to a Polyline.
Run IMAGECLIP command, select the image --”New boundary” --“Select Polyline”.

Please refer to my record steps:
