OS X wrong image signature
Posted: 2014-06-11T21:43:46-07:00
I am getting an unexepcted image signature on OS X. Stranger is the fact that I get different output depending on how IM was installed...
I also asked my coworkers to run the command (all use OS X) and they also got the wrong result.
Arch Linux, Windows, and Amazon Linux give the correct output (I hope).
Test command (also having the same problem with convert -identify)
expected output (image signature): 4cfd67bfba32fa8a46ed20b9e1c1656508cc573f7e4bde90268fa024b220d0cd
bad output on OS X 10.9.3 (IM installed using homebrew)
bad output on OS X 10.9.3 (IM installed using MacPorts)
good output on Arch Linux 3.14.6-1-ARCH x64 (installed using packer)
good output on Windows 7 Home Premium SP1 x64 (installed using http://www.imagemagick.org/download/bin ... 64-dll.exe)
good output on Amazon Linux AMI release 2014.03 (installed from Amazon Repository)
I also asked my coworkers to run the command (all use OS X) and they also got the wrong result.
Arch Linux, Windows, and Amazon Linux give the correct output (I hope).
