fakeimage

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 git@github.com: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.
