[magick-users] A grid appears when resizing. It wasn't invited. (Bug?)

[Seth Price]

"Box" shows the exact same behavior.

Another bug which may be related: resizing to 1080px results in all  
black except for the upper left corner. Resizing to 1600px results in  
a normal image.

I'm guessing it's not the point release because I've been having a  
similar problem (the above bug) since June. I should mention that my  
quantum size is set to 8 bits.


I also received this email confirming the problem:

Hi Seth,
FYI: I tried a couple of variations of your command on
Windows XP with IM 6.3.5 Q8 and both the Box and Point
filters generate that weird grid but the Lanczos
filter does not.

P.S. I have to reply direct to you because the IM
reflector won't accept email from my ISP because it's
listed in the SORBS database.
