MagickFilter

A powerful yet very simple to use gem to apply all sorts of cool instagram types of filters to your images or photos in your Ruby on Rails application. With this gem you can use all sorts of filters like Poster, Sepia, Navy, Sketch etc. You can apply frames of different types of frames with different colours to your images or photos as well.

This Gem is an attempt to build Ruby Gem and release it to rubygems.org. Latest version of this gem allows you to add frame to existing photo. This Gem is in early stage. I'll keep on adding some more filters and features with time.

This Gem is based on Image Magick, So please make sure that you have image magick installed on your system.

Installation

Add this line to your application's Gemfile:

gem 'magick_filter'

And then execute:

$ bundle

Or install it yourself as:

$ gem install magick_filter

Usage

1. Latest version of this Gem supports adding frames to photo with different colors. You can choose any desired color for frame from ImageMagick color list

   MagickFilter::Tool.apply_frame(image_path, frame_color, frame_type) 
   

   a) Option 1st => Basic Frame
   MagickFilter::Tool.apply_frame(image_path, "snow", "basic")
   b) Option 2nd => Sunken Frame
   MagickFilter::Tool.apply_frame(image_path, "snow", "sunken")             
   

   Different color options example - 
   a) MagickFilter::Tool.apply_frame(image_path, "snow", "basic")
   b) MagickFilter::Tool.apply_frame(image_path, "LightPink", "BASIC")
   c) MagickFilter::Tool.apply_frame(image_path, "SlateBlue1", :basic)
   

Default frame type is "basic", frame_type is case insensitive. You can add "basic", "BASIC" or :basic

1. In present there are 12 filters available in this Gem. Use the given below commands ( from Filter Examples section ) on console to convert photos.

   MagickFilter::Tool.process(image_path, filter_type)
   

   a) MagickFilter::Tool.process(image_path, "sketch")
   b) MagickFilter::Tool.process(image_path, "BRIGHT")
   c) MagickFilter::Tool.process(image_path, :sepia)
   d) MagickFilter::Tool.process(image_path, "rough")
   

Filter type is case insensitive, you can add "sketch", "SKETCH" or :sketch
