To view a PPM image on a Mac you can use the preview app that comes preinstalled. On a PC, you can download the File Viewer Plus app from the Microsoft Store. Two tiny PPM images are included with this assignment. You can open them in a text editor to gain a better understanding of how PPM files are organized. Both images have a greenish background with a red line from the top left to the bottom right corner. The tinyl.ppm file is 5 x 5 pixels and the tiny2.ppm file is 20 x 20 pixels.
