This code is a submission for the Makers Academy week 6 test; a simulation of a basic graphical editor.
graphical_editor is the executable in the top-level directory.
- On start it lists all commands, including help
- It then prompts for a user command and loops until user wishes to exit
- Invalid commands or command parameters (all uppercase) are met with a prompt to try again or consult the help
The final unit test in /spec/editor_spec.rb does a demonstration of several commands to draw 'HELLO !' and then fills the background region. The 'O' in 'HELLO !' remains unfilled, as a demonstration of how fill works - i.e. it crosses to adjacent pixels of the same colour, but does not cross diagonally connected pixels.
