I would be interested in this script, I'm also interested in robs mention of pre blur prior to scaling, this is a new method to me and could you possible explain further.
I use the pre-blur in "Scale Down Neat" the filter was discussed here
viewtopic.php?f=28&t=5343&start=30&hilit=scale+down+neat and there also link for a more generic discussion on pre blur and scaling
Testing i found the theoretical amount of pre-blur a bit excessive for the type of images i edit (3D renders and photo manipulation )
Less , as 2 px of gaussian blur to scale down 4:1 a 4,800X3,600 still minimize aliasing, but has a better effect on the very fine and sharp noise often present in 3d render :
it doesn't make the noise vanish but less intrusive, as a sort of vague texture that may even add the sensation of depth
"Automatic pre-blur" calculate and apply the blur according to the theory (2.00 to scale down 2:1, 3.00 to scale down 3:1 and so on
"Automatic pre-blur" may be switch off to allow manual fine tuning
