Source and Image Files

You will need to download the following files:

• image.h - Header file for the library that will be used in labs throughout the course. This contains the Image class. You will not need to modify this code in the course.
• image.cc - Source file for image.h. You will not need to modify this code in the course.
• Makefile - Contains instructions for the computer on how to compile our code.
• lab1-skeleton.cc - Outline for the source file for this lab. You will need to modify this code in the lab.

You will also need the following image:

• test_image.png - Input image for this lab.

Compiling Source Code

To compile the code for this lab for the first time, follow these instructions:

1. Download the required files to a directory on your workstation.
2. Copy the skeleton code to the file that the Makefile is looking for by typing:
   cp lab1-skeleton.cc lab1.cc
3. Build the program by typing:
   make lab1

Testing Code and Previewing Images

Your program will take two arguments. The first is the input image file, and the second is the output image file. After successfully compiling your code, the following command will test your program:

Before you make changes to lab1.cc, this will create a file output.png that will be identical to the input image. You can preview the image by typing:

When you have successfully completed the lab as outlined in the instructions, your output image should look like the image provided in the solutions.
