Middleman Dragonfly Thumbnailer
Middleman Dragonfly Thumbnailer is a Middleman extension that lets you easily create thumbnails using Dragonfly's fantastic thumb processor.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install middleman-dragonfly_thumbnailer
Just add the following to your config.rb file:
<%= thumb_tag 'image.png', '100x100#', class: 'thumbnail' %> <%= thumb_tag 'image.gif', '100x100#', format: 'jpg', frame: 1, class: 'thumbnail' %>
The second argument is a geometry string which specifies the dimensions and options such as aspect ratio and cropping. You can also change the output format and choose the frame for GIFs. Have a look at https://markevans.github.io/dragonfly/imagemagick for examples of what you can do. Any other options will be passed to the image_tag helper.
When running Middleman in development, thumbnails will be generated on the fly and encoded in data URLs.
During a build, the thumbnails will be saved next to original image in a sub directory named using the geometry string, so the thumbnail for
images/image.png will be saved as
