Processing Class 5: Images, Video and Saving

Hello Class. This week we are going to revisit nested for loops to move through images and grab data. We are also going to explore how to use video, both local files and a webcam. After we get through that we will learn how to save out versions of our sketches for others to see.

Images:

Processing has a native data type specific to images called PImage. Anytime you want to work with an image you need to use a PImage. The PImage object has multiple properties. Some of them are an array of pixel color value, width, and height. Images that are made up of a grid of pixels are called raster graphics.

Video:

Video requires using the video library from processing. We will explore basic use so that we have a better understanding of how to use libraries for next weeks class.
