Thanks for the report. You must have been the only person with a cpu without sse3 to try it because the automatic optimization detection wasn't correct. For opt=0 it always used sse3 routines. For right now you'll have to set opt manually for processors without sse3. Fixed in next version.

Are you saying you get that error when height is actually mod 2? Or just that you get that error on images that don't have mod 2 height? In the second case, just crop a line or add a line and remove it later. I'll remove that restriction for dh=true operation in the next version.

Maybe, you are free to try
. I think it's unlikely to make any useful difference.
