I am trying to install ImageMagick on Windows. What I did is install Windows RailsInstaller created my version and now I need to use ImageMagick but for some reason it doesn't work.

I took the binary source code and install and run it from this page but didn't seem to do the trick Link

I also try the following http://www.youtube.com/watch?v=gEWAVlNCKhg but it doesn't work

For the first example In cmd all I have to do is the following command to my understand to make it work here what I get

C:\Sites\case>convert wizard: wizard.jpg
Invalid Parameter - wizard.jpg

C:\Sites\case>convert wizard.jpg
Invalid drive specification.

C:\Sites\case>convert logo: logo.gif
Invalid Parameter - logo.gif

C:\Sites\case>$ convert logo: logo.gif
'$' is not recognized as an internal or external command,
operable program or batch file.

C:\Sites\case>

Then i saw this. From the https://github.com/rmagick/rmagick which state it include rmagick but then i run bundle and get this

Installing rmagick (2.13.2)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension

Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling.

Thank for any help.

Here yo go, to install ImageMagick and build the RMagick gem and make it all work.

Follow below steps:

  1. Go here mirror images.
  2. Download ImageMagick of any version except the currently latest release, which has some issues
  3. Install it with options: Add to PATH and development headers. Installation path should not contain spaces.

  4. In the command line type convert -version to check if everything works. It should print something like:

    Version: ImageMagick 6.6.1-10 2010-05-15 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2010 ImageMagick Studio LLC Features: OpenMP

  5. Install the DevKit if you haven't already.

  6. Install the rmagick gem: gem install rmagick --platform=ruby -- --with-opt-lib=c:/ruby192/ImageMagick/lib --with-opt-include=c:/ruby192/ImageMagick/include

(Making sure the paths point to wherever you installed imagemagick)

It should print

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...

And after a few minutes if everything goes right, you should see

Successfully installed rmagick-2.13.1
1 gem installed
Installing ri documentation for rmagick-2.13.1...
Installing RDoc documentation for rmagick-2.13.1...

And that's it. Just two more links that were helpful: 1 blog and 2 blog if you still can't install

  • Seems good but you actually need to `prepend` the imagemagick bin dir to path, not just add it. – pguardiario Jun 08 '13 at 09:01

    The link is now broken. – Aux Nov 26 '13 at 15:49

    It looks like one of the issues with v7 is that the CLI has been renamed to "magick" instead of "convert"... so that broke some things for me (finding instead `system32/convert` per @john-pankowicz's comment below). – zrisher Jul 13 '17 at 23:39
  • check here for mirrors with older versions http://www.imagemagick.org/script/mirror.php – Aralox Aug 17 '19 at 10:58
  • As per @zrisher's comment, **on Windows**, need to change script commands from `convert ...` to `magick ...`. E.g. to check it is there, do `magick -version`. There no longer is "convert.exe" in the magick installation. – ToolmakerSteve Oct 01 '20 at 14:56

  • The first one is a path issue. There is a convert.exe that is getting found before the ImageMagick one.
  • The second one is because you don't have working build tools.

    pguardiario is exactly right. There is a convert.exe in c:\windows\system32. It is for converting a FAT volume to NTFS. It expects to be passed a drive letter. That is why it says "Invalid drive specification." I put ImageMagick at the start of the path and now not only did the ImageMagick test commands work, but I was able to install the Rmagick gem with no problem. – John Pankowicz Oct 23 '14 at 21:14
  • In current releases, need to change script commands from `convert ...` to `magick ...`. E.g. to check it is there, do `magick -version`. There no longer is "convert.exe" in the magick installation, so changing path variable will not help. – ToolmakerSteve Oct 01 '20 at 14:59

How to install ImageMagick on Windows 8.1, as of 5/1/2017:

  1. take a deep breath

  2. uninstall imagemagick/rmagick/everything that's failed so far

  3. make sure you have the DevKit that the accepted answer linked to

  4. Don't download the current v7 of ImageMagick. I have no idea why, but it doesn't work. Instead download ImageMagick-6.9.8-4-Q16-x86-dll.exe from here

  5. Install, including the headers. Since it's V6, it includes legacy utilities already so you don't have to worry about that. Install into your C: directory so there are no spaces in the path.
  6. Open up your environment variables. You know, System>advanced system settings>environment variables.
  7. Find PATH in system variables, edit and copy and paste the large variable value into a notepad or something so you can read it properly.
  8. Find ImageMagick's path, cut it out and paste it to the front. My PATH starts with "C:\ImageMagick-6.9.8-Q16;..." If it's not there, add it yourself.
  9. Update your PATH with ImageMagick at the front.
  10. You should be all setup, go into command prompt and type "convert -version". Rather than a "Invalid drive specification" result which drove me insane, you should see the current version specifications.
  11. Bobs your uncle, you have ImageMagick!

Install ImageMagick windows binaries from https://sourceforge.net/projects/imagemagick/files/im6-exes/, findout where is it installed

Like

C:\Program Files (x86)\ImageMagick-6.7.9-Q16

or some other directory, depending upon your system...

And run following commands in command prompt

set CPATH=C:\Program Files (x86)\ImageMagick-6.7.9-Q16\include
set LIBRARY_PATH=C:\Program Files (x86)\ImageMagick-6.7.9-Q16\lib
gem install rmagick

Replacing

C:\Program Files (x86)\ImageMagick-6.7.9-Q16

with directory where you actually installed Image Magick
