Pixels to Pictures Supplemental Material    

"Pixels to Pictures" is free courseware authored by MathWorks® to help teach students "the basics of programming while they edit images, build GIFs, and create color filters and face masks that are applied in popular apps."

Recommended Ages: 10+

This repository provides additional MATLAB® live scripts and functions to supplement the Pixels to Pictures courseware. The Courseware Overview is broken down into 5 days. I teach this material through CoderDojo over the course of 10 lessons (roughly half a "day" per lesson). As such, the supplemental scripts refer to these lesson numbers instead of the Course Overview day numbers.

Short walkthrough videos for the first five lessons can be found on my CoderDojo MATLAB YouTube playlist. (Note, as described below, some of the setup steps have changed.)

Getting Started

The supplemental lessons can be used in one of two ways:

1. Open the supplemental project by double-clicking on the P2P-Supplement.prj project file from the MATLAB File Panel. This sets everything up for you, and needs to be done each time you open MATLAB and want to use this material.

2. Or, if you already have the base Pixels to Pictures content installed with the corresponding PixelstoPictures.prj project open, you can run these supplemental lessons by navigating to the supplemental "lessons" folder in MATLAB. (This approach provides direct access the Image Library that comes with Pixels to Pictures.)
