Matplotlib figure to image as a numpy array

We can use the following steps to convert a figure into a numpy array −

• Read a figure from a directory; convert it into numpy array.

• Use imshow() method to display the image.

• Use show() method to display it.

Example

from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
im = plt.imread("bird.jpg")
print("Numpy array of the image is: ", im)
im = plt.imshow(im)
plt.show()

Output

When we execute the code, it will show "bird.jpg" in a plot and show its numpy array on the console.

Numpy array of the image is: [[[162 162 170]
[162 162 170]
[160 163 170]
...
[ 97 98 92]
[ 98 100 95]
[ 94 96 91]]

[[159 159 167]
[159 159 167]
[157 160 167]
...
[ 94 95 89]
[ 95 97 92]
[ 92 94 89]]

[[157 158 163]

[154 157 164]
...
[ 93 94 89]

...

[[164 164 166]

[163 163 163]
...
[145 116 98]
