IMG_ROT

Name


      IMG_ROT

Purpose


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

Category


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.

Keyword Parameters


Keywords


        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


Notes


      Note: deals with 2-D or 3-D image arrays and rotates
        correct image planes.
