"-morphology thicken" in v7

[snibgo]

This seems to be broken in v7. I use an example from http://www.imagemagick.org/Usage/morphology/#thicken

Input man.gif


v6.9.9-50 (correct result):

Code: Select all

convert man.gif -morphology Thicken 3x1+2+0:1,0,0 mn_thk_v6.gif

v7.0.7-28 (bad result):

Code: Select all

magick man.gif -morphology Thicken 3x1+2+0:1,0,0 mn_thk_v7.gif

I can't see anything in http://www.imagemagick.org/script/porting.php that would explain this problem, but I might have missed something.

I can confirm the same issue on IM 7.0.8.45 Q16 Mac OSX
