ImageMagick Install Windows

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

• 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.

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!
