PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. The ImageEnhance module contains a number of classes that can be used for image enhancement.
ImageEnhance.Color() method –
This class can be used to adjust the color balance of an image, in a manner similar to the controls on a color TV set. An enhancement factor of 0.0 gives a black and white image. A factor of 1.0 gives the original image.
Syntax: ImageEnhance.Color(image)
First, it is required to create an object of corresponding class in order to enhance image.
# This will import Image and ImageEnhance modules from PIL import Image, ImageEnhance # Opening Image im = Image.open(r"C:\Users\Admin\Pictures\images.png") # Creating object of Color class im3 = ImageEnhance.Color(im) # showing resultant image im3.enhance(0.0).show() |
Output:
For first image factor = 0.0 and for second image factor is 5.0.
ImageEnhance.Contrast() method –
This class can be used to control the contrast of an image, similar to the contrast control on a TV set. An enhancement factor of 0.0 gives a solid grey image. A factor of 1.0 gives the original image.
Syntax:
obj = ImageEnhance.Contrast(image)
obj.enhance(factor)First, it is required to create an object of corresponding class in order to enhance image.
# This will import Image and ImageEnhance modules from PIL import Image, ImageEnhance # Opening Image im = Image.open(r"C:\Users\Admin\Pictures\images.png") # Creating object of Contrast class im3 = ImageEnhance.Contrast(im) # showing resultant image im3.enhance(0.0).show() |
Output:
For first image factor is 5.0 and for second 0.0
