A small Sinatra app influenced by http://dummyimage.com, but written in Ruby.
Try it online at http://fakeimage.heroku.com
Requires ruby 2.4.1. May work with older versions, but not tested or supported.
gem install bundler
bundle
ruby fakeimage.rb (or your rack-app-handler of choice)A Dockerfile and docker-compose.yml are included in the distribution if preferred. Getting up and running
locally should require nothing more than docker-compose up in that case.
In a browser, hit http://localhost:4567/300x200 for example, or change bg and text colors by passing them as GET params:
http://localhost:4567/95x150?color=red&textcolor=orange
Leave off the second dimension for a square.
http://localhost:4567/200
Multiple image formats are supported. Just add an extension to the size (e.g. http://localhost:4567/300x200.gif) to get that format. png (default), gif, and jpg are supported currently.
See the ImageMagick documentation for the canonical list of colors. Hex colors are also supported, but with the # replaced with a !, like http://localhost:4567/400x300?color=!849593.
