How to Read an Image using Matplotlib in Python

by ganesh Updated: Jan 17, 2023

As developers, we encounter many situations where we need to read images in our applications for image-processing tasks, including recognition, upload, enhancement, training, and many others.


Python has many libraries that provide the ability to work with images. The image capabilities in Python include image manipulation, enhancement, etc. Python users frequently use Matplotlib to build static, animated, and interactive visualizations. It offers a sophisticated drawing tool for creating eye-catching and educational statistical visuals. Matplotlib is designed to be used with the broader SciPy stack, which includes tools for working with arrays, numerical optimization, and data analysis. It is frequently combined with other libraries, such as NumPy and Pandas, to provide robust and engaging data visualizations. You can use the imread() function from the matplotlib.pyplot module to read an image in Python using matplotlib. This function accepts a string representing the image's path and returns a numpy.ndarray object with the image's pixel information. Note that the imread() function can only read image files that are supported by matplotlib, such as PNG, JPG, and BMP. You will get an error if you try to read an unsupported image file. 


Here is an illustration of how to read a picture in Python using matplotlib:

Code

In this solution we use the Imread function of the Matplotlib library.

  1. Copy the code using the "Copy" button above, and paste it in a Python file in your IDE.
  2. Modify the name, location of the image to be read in the code.
  3. Run the file to read the image.


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for "read image in python" in kandi. You can try any such use case!

If you do not have Matplotlib that is required to run this code, you can install it by clicking on the above link and copying the pip Install command from the Matplotlib page in kandi.

You can search for any dependent library on kandi like Matplotlib.

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in Python3.9.
  2. The solution is tested on Matplotlib 3.4.3 version.

Using this solution, we are able to read an image using the Matplotlib library in Python with simple steps. This process also facilities an easy to use, hassle free method to create a hands-on working version of code which would help us read an image in Python.
