This function, red_channel, returns a red-shaded version of an image. Makes image darker by halving red, green, blue values Reads image from file specified by filename. This function, darker, returns a darker version of an image. pixel,red, een, pixel.blue Now, let's look at some examples. Higher R, G, B values means that there is more of that color present in the pixel. You can also get the RGB values of a pixel, which are integers between 0 and 255. You can get the x and y coordinates of a pixel in an image: pixel.x, pixel.y For example, this is how you can access the width and height of an image: image.width, image.heightĮach pixel in an image also has properties: # The code here gets repeated once for each pixel in imageĮach SimpleImage image has properties you can access. Here's how to use a for-each loop with an image: image = SimpleImage("flower.jpg") 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
