Hi, thanks for your package !
I just want to report this error:

Works for me. What does Images.have_imagemagick report? How about run(which identify)?

[cmey]

julia> Images.have_imagemagick
true

julia> run(which identify)
ERROR: failed process: Process(which identify, ProcessExited(1)) [1]
in pipeline_error at process.jl:447
in run at process.jl:424

in a terminal:

OK, this looks like a dupe of #15. Can you try a HomeBrew install? Or see http://www.imagemagick.org/script/binary-releases.php#macosx.

I think the best solution will be to transition away from ImageMagick. I will work on this between now and the end of the year, starting with PNG. CC @rened, who has expressed similar interests.

Thanks, yes it looks like a dupe of #15. However, I don't get what Dahua did to make it work.
Not sure what you mean by trying a HomeBrew install.

I tried to install imagemagick using homebrew from terminal, it installed it but then no more luck with Images,
I tried to use the Julia package HomeBrew, but didn't succeed in using it:

julia> using Homebrew

julia> Homebrew.add("imagemagick")
Error: No available formula for imagemagick 
Please tap it and then try again: brew tap staticfloat/juliadeps
ERROR: failed process: Process(`/Users/cmey/.julia/Homebrew/deps/usr/bin/brew info staticfloat/juliadeps/imagemagick`, ProcessExited(1)) [1]

 in add at /Users/cmey/.julia/HomeBrew/src/HomeBrew.jl:126
 in add at /Users/cmey/.julia/HomeBrew/src/HomeBrew.jl:119

I tried brew tap staticfloat/juliadeps as suggested in this error message, but still no luck.

OK Got it working by installing the mac distribution directly from the imagemagick website (as you suggested as alternative):

tar xvfz ImageMagick-x86_64-apple-darwin12.5.0.tar.gz
export MAGICK_HOME="$HOME/Downloads/ImageMagick-6.8.7"
export PATH="$MAGICK_HOME/bin:$PATH"
export DYLD_LIBRARY_PATH="$MAGICK_HOME/lib/"

julia> using Images
julia> imread("/Users/cmey/Downloads/Chrism.jpg")
RGB Image with:
  data: 3x369x492 Array{Uint8,3}
  properties:
    limits: (0x00,0xff)
    colordim: 1
    spatialorder:  x y
    colorspace: RGB

Yay ! Thanks :)

[timholy]

Hooray, that's great!

I'm going to close this one specifically, but then open an issue to remind me to move away from ImageMagick.

Thanks again for sticking this through.
