installed the package
brew install imagemagick
Test that it worked
# imagemagick ships w/ a few default images
# logo is the variable name of a built-in image
# this cmd saves a new file to your working directory called logo.gif
convert logo: logo.gif
# print some stats about the image
identify logo.gif
# display the image in an XQuartz X11 server
# THIS FAILS
display logo.gif
