#This program loads an image, displays it, and then creates, displays

#and saves a new image that has only the green channel displayed.


#Import the packages for images and arrays:

import matplotlib.pyplot as plt


inputFile = input("Enter name of the input file: ")

outputFile = input("Enter name of the output file: ")


img = plt.imread(inputFile)
#Read in image from csBridge.png


img2 = img.copy()
#make a copy of our image
img2[:,:,0] = 0
#Set the green channel to 0
img2[:,:,2] = 0
#Set the blue channel to 0


plt.imsave(outputFile, img2)
#Save the image we created to the file: reds.png
