For apps built before the image_processing gem became the default, the migration will involve two steps:

1. Migrating to the image processing syntax while still using ImageMagick;
2. Switching to Vips and updating the compression options;

Migrate to the image processing syntax

Before changing from ImageMagick to Vips, it's better to first test the new syntax and ensure everything is still working.

1. Move everything that has to do with compression to a saver hash:

Hi Pericles,

This morning I took a quick look at how ActiveRecord converts the query result
back into Ruby objects.

Here’s where it happens:

include

#homebrew > cask > Virtualbox > Vagrant > CentOS > Docker > Ubuntu  

$ ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
$ brew tap caskroom/homebrew-cask
$ brew install brew-cask
$ brew cask install virtualbox
$ brew cask install vagrant
$ brew tap homebrew/completions
$ brew install vagrant-completion
