Can't use ImageMagick on Laravel 5 with Intervention Image

I followed these steps http://ift.tt/1i0tPWB for install Intervention Image library on Laravel 5. For now GD library is working which comes as a default library but i want to use imagemagick for this function http://ift.tt/2dHGfNl . I ran $php artisan vendor:publish --provider="Intervention\Image\ImageServiceProviderLaravel5" command for pull configuration file into my application but i got Publishing complete for tag[]! message and nothing change. So what is my mistake or am i missing something?
