Image Colors L ETS START THIS WITH some fun image programming. Its always nice to have some fun programming up your sleeve, and this code will give you just that. In this chapter we will look at codes to help you change the color of an image, so you can make it look the way you want it to. This code will give you some fun things to do to your images when coding.

Its also just a fun thing to play around with. 1. Type the following in a Python IDLE window. CODE: from ImageLibrary import * myfile=pickAFile() pict=makePicture(myfile) show(pic) This tells Python to use every function that is in your image library. This should not be done in a main window. You need to write this in a new window.

Do this by choosing, file -> New Window and then paste the code in an empty window, then pick run. You will then be asked if want to save your file. The file needs to be saved in an arbitrary location. The from ImageLibrary import* needs to be placed into every IDLE window. myfile=pickAFile() lets the computer know you need a window that you can pick the .jpg image file that you want to play with. pickAFile() will give you a return of the full name of your image file. 2. 2.

Ask Python to print myfile so you will be able to see how the image looks. As a reminder, print command looks like print myfile. The string should look like: C:/Users/Public/Pictures/image.jpg That means myfile is a string that states the picture that you want. You could use a string so you wont have to call pickAFile() each time that you need anything new. Like this: pic=makePicture(/users/nameGoesHere/Pictures/image.jpg) Make your picture: from ImageLibrary import * filename=pickAFile() pic=makePicture(filename) show(pic) This will load you picture into memory so you can change it. You dont need to call makePicture(myfile) unless you plan on putting the results in a useful place such as assigning it to a variable such as pic .

Make sure that you get the lower and upper case letters right because Python is case sensitive. Whenever you change something about the picture, you have to call show(pic) so you will be able to see your changes. Your changes do not update automatically when they are changed. 3. Open the image and display it CODE: from ImageLibrary import * myfile=pickAFile() pic=makePicture(myfile) show(pic) First thing you are going to do is make every red pixel level to 255: for p in getPixels(pict): setRed(p,255) show(pic) 3a. Change red, green, and blue levels until the image is black, then white, the green.

Another neat function is setColor(pixel,color) will change a pixel color. The list of predefined colors are cyan, magenta, pink, orange, yellow, darkGrey, lightGrey, grey, blue, green, red, black, white. You can also use this function to change a pixel color to orange instead of the regular blue, red, and green colors. 3b. Change the picture color using the for loop, setColor (pixel, color), and then you can use the colors that have already been defined. You can also use makeColor(redValue, greenValue, blueValue).

This lets you create any color you want. To make purple you use: Purple=makeColor (255, 0, 255) 3c. Play with r, g, b values to figure out how to create yellow color. Use the earlier code to make the change to the complete picture. You can use the makeLighter (color) function to lighten parts of color. It actually subtracts 40 from each main color green, red, and blue.
