This program is intended to take an image file and convert it into a P3 .ppm file. This can be done in two ways:
It is by far easier to download the Image_to_ppm.py file directly as it is only one 878 byte file.
To run the script, you will need numpy, OpenCV, and skimage packages installed. If you don't, you can install them with
pip3 install numpy
pip3 install scikit-image
pip3 install opencv-python
Then, to run the script, all you need to do is run the command
python3 Image_to_ppm.py <source_image>. It will create a new .ppm file in the same directory where you run the script. Note you do not actually have to be in the same directory as Image_to_ppm.py, but it saves you having to write out the full filepath.
If you don't want to install a bunch of python packages, you can run it from the compiled executable. To do so, run the following command:
<filepath to Image_to_ppm executable> <filepath to image>
Example:
Daniels-MacBook-Air:~ danieh65$ cd Desktop
Daniels-MacBook-Air:Desktop danieh65$ ls

Executable trump-laughter-un.jpg
Pictures trump-laughter-un.new.ppm
Daniels-MacBook-Air:Desktop danieh65$ /Users/danieh65/Desktop/Executable/Compiled\ files/Image_to_ppm /Users/danieh65/Desktop/trump-laughter-un.jpg
Daniels-MacBook-Air:Desktop danieh65$ echo "The following also works."
The following also works.
