What would be the most efficient way to get this to work in IDL. This is
obvious slow with the FOR DO BEGIN.....

============================================================ ===============

nx = 1024
ny = 768
North_bound = 3429
West_bound = 9249
line_res = 4
elem_res = 8
LINarr = LONarr(nx*ny)
PIXarr = LONarr(nx*ny)
k = 0L
FOR y = 0, ny-1 DO BEGIN
FOR x = 0, nx-1 DO BEGIN
LINarr(k) = North_bound + ( y * line_res)
PIXarr(k) = West_bound + ( x * elem_res)
k = k + 1L
ENDFOR
ENDFOR
