procedure shift
Shifts (and optionally wraps) X by specified values.
Syntax
shift X, xs, ys [, zs] [, /wrap]
Arguments
| X: | The array to be shifted |
| xs: | Shift vector in the first dimension |
| ys: | Shift vector in the second dimension |
| zs: | Shift vector in the third dimension |
Switches
| wrap: | Pixels shifted off the array will be wrapped to the opposite side. |
Notes
If either shift vector is non-integer, a subpixel shift is applied and the array type changed to R4. Subpixel shift is only supported in 2 dimensions.
