It is basically a couple of stateless module methods that make it somewhat more convenient than calling ImageMagick by hand. The main reason to use MojoMagick is that you should consolidate your ImageMagick calls into one place, so why not do it here? If you improve on this tool, send me the patch. This tool came about because I wanted a fast, simple, lightweight, nothing-goes-wrong-with-it- because-it's-too-simple-to-break image tool. [![Gem Version](https://badge.fury.io/rb/mojo_magick.png)](http://badge.fury.io/rb/mojo_magick) Using it ======== Add to your Gemfile gem 'mojo_magick' Require it in your ruby code require 'mojo_magick' Go to town! Check out a couple of simple [examples, here](examples/) Examples ======== ## Image Resizing ### Obtain the size of an image (assuming image is "120wx222h") dimensions = MojoMagick::get_image_size(test_image) # ==> dimensions now holds a hash: {:height => 120, :width => 222} ### Resize an image so that it fits within a 100w x 200h bounding box (Note: this will scale an image either up or down to fit these dimensions which may not be what you want.) In this example, we overwrite our image, but if you pass in a different file for the second file name, a new file will be created with the resized dimensions MojoMagick::resize('/img/test.jpg', '/img/test.jpg', {:width=>100, :height=>200}) ### Resize an image so that it fills a 100 x 100 bounding box After this transformation, your image's short side will be 100px. This will preserve the aspect ratio. MojoMagick::resize('/img/infile.jpg', '/img/outfile.jpg', {:width=>100, :height=>100, :fill => true}) ### Resize an image so that it fills and is cropped to a 100 x 100 bounding box After this transformation, your image will be 100x100. But it does not distort the images. It crops out of the Center. MojoMagick::resize('/img/infile.jpg', '/img/outfile.jpg', {:width=>100, :height=>100, :fill => true, :crop => true}) ### Code sample of how to shrink all jpg's in a folder require 'mojo_magick' image_folder = '/tmp/img' Dir::glob(File::join(image_folder, '*.jpg')).each do |image| begin # shrink all the images *in place* to no bigger than 60pix x 60pix MojoMagick::shrink(image, image, {:width => 60, :height => 60}) puts "Shrunk: #{image}" rescue MojoMagick::MojoFailed => e STDERR.puts "Unable to shrink image '#{image}' - probably an invalid image\n#{e.message}" rescue MojoMagick::MojoMagickException => e STDERR.puts "Unknown exception on image '#{image}'\n#{e.message}" end end ## Setting Memory/Resource limits for ImageMagick Be sure you're upgraded to the current release of ImageMagick. set limits on disk, area, map and ram usage obtain/print a hash of default limits: puts MojoMagick::get_default_limits.inspect current\_limits shows same values: puts MojoMagick::get_current_limits.inspect MojoMagick::set_limits(:area => '32mb', :disk => '0', :memory => '64mb', :map => '32mb') puts MojoMagick::get_current_limits.inspect As of ImageMagick 6.6, you also have the ability to set `:threads` and `:time`. Read [ImageMagick docs on limits](http://www.imagemagick.org/script/command-line-options.php#limit) for more info. ## For more complex operations (thanks to Elliot Nelson for adding this code to the system) Two command-line builders, #convert and #mogrify, have been added to simplify complex commands. ### using #convert MojoMagick::convert('source.jpg', 'dest.jpg') do |c| c.crop '250x250+0+0' c.repage! c.strip c.set 'comment', 'my favorite file' end # Equivalent to: MojoMagick::raw_command('convert', 'source.jpg -crop 250x250+0+0 +repage -strip -set comment "my favorite file" dest.jpg') ### using #mogrify MojoMagick::mogrify('image.jpg') {|i| i.shave '10x10'} # Equivalent to: MojoMagick::raw_command('mogrify', '-shave 10x10 image.jpg') # Example showing some additional options: # assuming binary data that is rgb, 8bit depth and 10x20 pixels, :format => :rgb, :depth => 8, :size => '10x20'OAu MojoMagick::convert do |c| c.file 'source.jpg' c.blob my_binary_data, :format => :rgb, :depth => 8, :size => '10x20' c.append c.crop '256x256+0+0' c.repage! c.file 'output.jpg' end # Use .file to specify file names, .blob to create and include a tempfile. The # bang (!) can be appended to command names to use the '+' versions # instead of '-' versions. ### Create a brand new image from data binary_data = '1111222233334444' MojoMagick::convert do |c| c.rgba8 binary_data, :format => :rgba, :depth => 8, :size => '2x2' c.file 'output.jpg' end ### Get a list of available fonts fonts = MojoMagick::get_fonts fonts.first => # ### Create a new image with text Note: Use with care. If you don't have fonts installed ImageMagick can spin off wildly leaving MojoMagick not knowing what to do. For Unix/MacOSX, you should install `freetype` and `ghostscript`. MojoMagick::convert(nil, fname) do |c| c.background 'black' c.fill 'white' c.gravity 'center' c.pointsize 80 c.size '200x200' c.label 'the bird is the word' end ### Generate a composite MojoMagick::convert(nil, 'composite_out.png') do |c| c.size '200x200' c.image_block do # first layer c.background 'blue' c.fill 'white' c.gravity 'northwest' c.label 'NW' end c.image_block do # second layer c.background 'transparent' c.fill 'red' c.gravity 'southeast' c.label 'SE' end c.composite end Dependencies ============ This library has (in the past) been good for ruby 1.8.7 and beyond. Recent mods (as of 0.5.x) will require a more recent ruby (>1.9.3). If you're running on 1.8.7, you should be able to safely use 0.4.3 Do this by pinning it in your Gemfile gem 'mojo_magick', '0.4.3' Availablility ============= * [Github Repo](http://github.com/rcode5/mojo_magick) This is the current canonical branch. * Issues/Pull Requests can be submitted through the above repository. Contributions ============= Got a fix? Got a feature? * fork it * make a branch (named appropriately) * write your code * write your tests * test it (`rake` will run the tests) * submit a pull request Note: please don't change the version. We'll do that when we merge in the new code Recent Changes ============== #### Version 0.5.4 * Include image magick commandline failure from raw_command (on failure) * moved to Popen3 * added checks for Popen3 on windows * updated README to include info about submissions * probably no good for ruby 1.8.7 anymore #### Version 0.5.1 * add `LICENSE.txt` and update README * add `examples/` directory * add support for fonts * add support for building multi-layer images with image blocks (no explicit temp file creation) * [Moved repo to rcode5](http://github.com/rcode5/mojo_magick) Current support and maintenance is happening here. * added `simplecov` for test coverage reports #### Versions 0.4.x * Add rake tasks for gem building and tests * code cleanup * better handling of `gravity` parameter #### Version 0.3.0 * Add new github repo * added gemspec for building gem with bundler * updated tests for ImageMagick 6.6 * added ability to do fill + crop resizing * bumped version to 0.3.0 * [new github repo](https://github.com/bunnymatic/mojo_magick) References ========== * [Original SVN MojoMagick repository](http://www.misuse.org/science/2008/01/30/mojomagick-ruby-image-library-for-imagemagick/) - Initiated and developed by Steve Midgley * [ImageMagick](http://www.imagemagick.org/) * [FreeType](http://www.freetype.org) * [Ghostscript](http://www.ghostscript.com/) Copyright (c) 2013 Jon Rogers Copyright (c) 2008 Steve Midgley, released under the [MIT license](LICENSE.txt) Credit to Elliot Nelson for significant code contributions.
