A small Sinatra app influenced by http://dummyimage.com.
Try it online at http://fakeimage.fly.dev
Requires Ruby 2.7+. May work with older versions, but not tested or supported.
gem install fakeimage
fakeimage --port 5000 # all arguments are forwarded to `rackup`git clone [email protected]:xxx/fakeimage.git
cd fakeimage
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.
