Here's what it looks like: for item in collection: We can use a new kind of loop called a "for-each" loop. To show the image on your computer: my_image.show() Accessing Pixels in an Image You can create a SimpleImage object by reading an image from file (jpg, png, gif, etc.) and storing it in a variable my_image = SimpleImage(filename) This is similar to when you used import random to use the random number generator libraryĮach SimpleImage object is made up of Pixel objects Functions in SimpleImage Library This is importing the SimpleImage module, so that it is accessible in the code you write. To use the SimpleImage library in your code, include at the top of your program file: from simpleimage import SimpleImage This is the SimpleImage library, and you will use this library to work with images. In folders for assignment or lecture on images, there is a file simpleimage.py. y increases going down, x increases going right The origin (0,0) is at the upper-left corner. and the pixels that make up a picture of a dog:Įach pixel has x and y coordinates in the image. You can set RGB values to make any color!įor example, here's a close-up of the pixels that make up a scene from the Pixar movie Monsters Inc. Each value represents brightness for that color (red, green, or blue). Resize an image to be the same size as another imageĮach pixel has single color encoded as 3 RGB values, where R = red, G = green, and B = blue. We've reached an exciting step in your Python journey - images!Ĭolor properties: pixel.red, een, pixel.blueĬreate a blank image with specified dimensions
