Calculate the area of an image using Matplotlib
• Last Updated : 17 Aug, 2020

Let us see how to calculate the area of an image in Python using Matplotlib.

Algorith :

1. Import the `matplotlib.pyplot` module.
2. Import an image using the `imread()` method.
3. Use the `shape` attribute of the image to get the height and width of the image. It fetches the number of of channels in the image.
4. Calculate the area as, `area = height * width`.
5. Dislpay the area.

Example 1 : Consider the following image : “GFG.jpg”

 `# import necessary library``import` `matplotlib.pyplot as plt`` ` `# read an image``img ``=` `plt.imread(``"GFG.jpg"``)`` ` `# fetch the height and width``height, width, _ ``=` `img.shape`` ` `# area is calculated as “height x width”``area ``=` `height ``*` `width`` ` `# display the area``print``(``"Area of the image is : "``, area)`

Output :

`Area of the image is : 50244`

Example 2 : Consider the following image : “image.jpg”

 `# import necessary library``import` `matplotlib.pyplot as plt`` ` `# read an image``img ``=` `plt.imread(``"image.jpg"``)`` ` `# fetch the height and width``height, width, _ ``=` `img.shape`` ` `# area is calculated as “height x width”``area ``=` `height ``*` `width`` ` `# display the area``print``(``"Area of the image is : "``, area)`

Output :

`Area of the image is : 213200`
