If i understand what you want I will propose yoy this piece of code

pro wavelet_for_forum

x1 = read_tiff(filepath('image.tif',subdir =
['examples','data']))
z=128
x = congrid(x1, z,z ,/cubic)

info = wv_fn_daubechies(2, wavelet, scaling,ioff, joff)
wv_dwtpartial = wv_dwt(x,wavelet,scaling,ioff,joff, N_LEVELS = 2)

LL2=wv_dwtpartial[0:z/4-1,0:z/4-1]

tv, LL2

end

LL2 stands for the LL component of the second level

IF you want wavelet code more than what ITTVIS provides (eg a trous,
or Daubechies 7/9 wavelet etc) and without the limnitation of the
image been of the type: image[2^n, 2^n] (eg image[240, 458] without
the need of congrid) ask me
