Hi,

if you check the code from gauss_smooth you can see where the problem
occurs. Gauss_smooth generates internally a normalized kernel and then
fixes it to integer.

Based on this code you can do your own cuisine using convol:

a=intarr(800,800)
a[*,400]=1000 & a[400,*]=1000

; this call is necessary to compile "create_gaussian"
tvscl, gauss_smooth(a, 20)

; parameters are arbitrary, be careful
k = FIX(create_gaussian(20, 100, 2) * 100)
tvscl, convol(a, k, total(k))

Cheers,

Fabien
