Posted: 2016-10-28T17:49:15-07:00
From Anthony's page at http://www.imagemagick.org/Usage/masking/#alpha_shape, if saved to miff in IM 6.9.6.2, it does not work and one gets a black moon on transparency. If saved to mpc or png it works fine.
Input:
IM 6.9.6.2
Also using IM 7.0.3.4 Q16, all three result is solid red.
