I am converting a image (5 bands) to 1D using reform. I then apply a
function to this data and get a double "Array[3]"result. How do I then
convert this result back into the origional image dimensions? eg:

image= READ_IMAGE('test.tif')
imagesize = SIZE(image, /DIMENSIONS)
nx=imagesize[1]
ny=imagesize[2]
npix = nx*ny
coords_2d = array_indices([nx,ny], lindgen(npix), /dimen)
imageR= REFORM(image,5,npix)

I then apply a function to this data and get a return in the form of:

IDL> help, ret3
RET3 DOUBLE = Array[3]

I'm struggling to covert this back to a 3D image. Any ideas?
