Quite by coincidence, I happen to be sitting in front of the exact 
same Ubuntu version you are using.  It seems that the functionality is 
working for the command line:

  MAGICK_DEBUG=transform /usr/bin/gm convert logo: -filter blackman -resize '20%' null:
13:16:05 0:01 0.000u 25775 resize.c/ResizeImage/1281/Transform:
   Resizing image of size 654x418 to 131x84 using Blackman filter
13:16:05 0:01 0.010u 25775 resize.c/VerticalFilter/1006/Transform:
   Enter VerticalFilter() ...
13:16:05 0:01 0.010u 25775 resize.c/VerticalFilter/1177/Transform:
   Normal exit VerticalFilter()
13:16:05 0:01 0.010u 25775 resize.c/HorizontalFilter/809/Transform:
   Enter HorizontalFilter() ...
13:16:05 0:01 0.020u 25775 resize.c/HorizontalFilter/979/Transform:
   Normal exit HorizontalFilter()

Since it works for the utility, it can clearly work via the API as 
well since the utility uses the API.

What resize API function are you invoking and what parameters are you 
passing?
