Purpose

---

      Rotate a 2-D or 3-D image array by any angle.

Calling Sequence

---

      out = img_rot(in,ang,mag,x0,y0)

Inputs

---

      in = Input image. in
      ang = rotation angle (deg) in
      mag = Mag factor (def=1.0) in
      x0,y0 = x,y subscript to rotate about. in
        Same as for IDL rot.

        Same keywords as the IDL rot routine.
        ERROR=err error flag: 0=ok, 1=not 2-D or 3-D,
          2=wrong number of color channels for 3-D array.

Outputs

---

      out = Rotated image. out

Common Blocks
