I tried all the examples, Anthony. It's not working. It used to work 
just fine before. I haven't touched my code, it just broke after the 
upgrade to the latest IM :(

I even tried:

convert in.jpg -interpolate mesh -filter point -matte -background 
"transparent" -virtual-pixel transparent +distort SRT 5 out.jpg

to no avail

Any other ideas please?
