[magick-users] parenthesis not work in windowsXP

[Vu The Cuong]

I'm using windowsXP with imageMagick 6.4.1.

When I ran this command:

convert   eye.gif \(storm.gif  -negate \) +append  cmd_bracket.gif

IM warned "unable to open image \(storm.gif : no such file or directory.

 

What can I do to fix this?

Regards
