In this paired lab, you will work with a partner to build a bitmap transformer CLI.

• Bitmap Specification

• Create a new repo called bitmap-transformer for this paired lab, and ensure you’ve added your partner as a collaborator. Create a new Java application by running gradle init --type java-application.

For this assignment you will be building a bitmap (.bmp) transformer CLI. It will read a bitmap in from disk, run one or more color or raster transforms and then write it out to a new file. This project will require manipulating binary data. Your solution should be composed of small tested methods that solve specific problems. Your methods should be thoughtfully named and well documented. You should run ./gradlew run --args 'input output transform' to run your application. Your bitmap transformer modules should not use any third party libraries.

• The CLI should be architected using best modularization practices.
• The CLI should contain a Bitmap class, and reading in a file should create a new Bitmap instance.
• The CLI should require at least three arguments: input-file-path output-file-path transfrom-name.
• The CLI should support a minimum of three transforms, each of which is an instance method in the Bitmap class.
• The CLI should log useful Error messages if used incorrectly.
• The CLI should log a success message on completion.

• Use JUnit to define descriptive tests.
• Each @Test method should aim to test a small well defined feature of a function.
• Write tests to ensure each function behaves correctly with valid and invalid inputs.

You will want to define a strategy for solving the problem before you begin to code. Once you have a strategy defined, you can break it into steps that can be split into helper methods. Each helper method should solve a small specific problem. The main method should utilize the helper modules to execute your original strategy.

1. Gather user input (infile, outfile, and transform)
2. Read the input bitmap file
3. Parse the bitmap’s data into a Bitmap object (instance of a Bitmap class that you write)
4. Using data from the parsed Bitmap, run a transform on the data directly (mutate the color or similar)
5. Write the mutated image data to the output file path
