Lab 08

File structure:

• README.org - this file. fill out the top and use it for notes
• Makefile
• main.cpp - main driver
• funcs.h / funcs.cpp – add your functions here.
• test.cpp - add your tests
• doctest.h - testing library

The full text of the 136 version of the lab can be found here: https://maryash.github.io/135/labs/lab_06.html

Overall notes:

• Write your functions in funcs.cpp
• Write your tests in test.cpp
• I will test your program by running make test then ./test
• Don’t add .o, executable or any extraneous files to the repo
• You should commit and push your work frequently
• make sure to add sufficient tests to show that everything works

Specifc changes to the lab

Overall changes

• You do not have to download the sample image. It is in the repo and named test_image.pgm.
• The two functions in lab-images.cpp are already in funcs.cpp and funcs.h but have an additional first parameter - std::string filename so that you can load and save different image files easily. The sample code is already in main.cpp.

Tests

• This lab does not require doctests.

All the tasks.

For each task, write a function that creates an output image illustrating that it works. The output filenames should be:

• taska.pgm
• taskb.pgm
• taskc.pgm
• etc.

Running ./main should create all these image files with no user input.

Final note on image files

If you are using another image for any of the tasks, make sure to add it to the repo.
