Estou tentando instalar o ImageMagick no Windows. O que fiz foi instalar o Windows RailsInstaller, criei a minha versão e agora preciso usar o ImageMagick, mas por algum motivo não funciona.

Eu peguei o código-fonte binário, instalei e executei a partir desta página, mas não consegui fazer o truquehttp://www.imagemagick.org/script/binary-releases.php#windows

Eu também tento o seguintehttp://www.youtube.com/watch?v=gEWAVlNCKhg mas não funciona

Para o primeiro exemplo Em cmd tudo que eu tenho que fazer é o seguinte comando para entender que eu faço funcionar aqui o que eu recebo

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
'
Então eu vi isso. Dehttps://github.com/rmagick/rmagick que estado incluem rmagick mas depois eu corro pacote e obter este
