        TRUECOL_ROTATE

Purpose

---

        This a wrapper for the rotate function. Rotate doesn't like
        arrays from true colour images.

Category

---

        Graphics

Calling Sequence

---

        result = TrueCol_Rotate(img,dir)

Inputs

---

      img: The array holding a true colour image. true colour
              images have a format like (3,x,y) where the first index
              refers to the three different colour channels.
      dir: The direction argument passed to the IDL Rotate
              function. See the IDL Rotate function for more information.

Outputs

---

      result: The rotated array.

Restrictions

---

      The input array (img) must be of the form array(3,x,y) where x
      and y are the horizontal and vertical dimensions of the image.
      It would be easy to modify this routine to handle the other
      forms of true colour images (where the colour index is the
      second or third dimension instead of the first).
