Image-Blur-2

Solution and Tests to the Columbia University Image #2 problem.

Project structure

• lib/image.rb - contains solution
• spec/image_spec.rb - includes three different examples

Solution

• the method blank_matrix - gets as a parameter matrix and converts it to the matrix with the same dimention but with only zero values in it.
• the method blur - iterates through the matrix specified in a class constructor and if met ones it will replaces values in the matrix called transformed_matrix which is used as a result of the program. This method returns transformed_matrix as a result.
• the method output_image - converts matrix to string and prints it in a console

Test execution

• Run bundle install
• Open terminal window
• From the project directory run rspec
