mogrify -splice?

[aporthog]

-splice is listed as an option to mogrify here: http://www.imagemagick.org/script/mogrify.php

But I get an error when I try to use it:

mogrify -background white -splice 161x0 +repage image.tif
mogrify.exe: unrecognized option `-splice' @ error/mogrify.c/MogrifyImageCommand/5848.
