Why not use the Thumbnail Stack that Eric Chatonet has on his

Just use 1/2 * the Height and get a smoother jpg since you will be
sampling
to get the smaller image.
yes, but the downsizing is probably not performed by the
subsampling that Josh wanted (btw, Josh, do you have wavelet or sub-
band filtering in mind?)
Hi François,
Wow! I don't need those, but it is very impressive if you have
implemented those algorithms!
What I am hoping to do is simply throw away every other line and
construct a new image only consisting of every other line.
I wonder if there is a way to use some kind of crude "nearest
neighbor" resizing method where I can resize to 50%, that will not
blend the lines but just throw away every other one.
No need for all the looping and slow pixel-by-pixel work.
as I said, it's a different algorithm.
