Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface.
matplotlib.pyplot.imread() Function:
The imread() function in pyplot module of matplotlib library is used to read an image from a file into an array.
Syntax: matplotlib.pyplot.imread(fname, format=None)
Parameters: This method accepts the following parameters.
- fname : This parameter is the image file to read.
- format: This parameter is the image file format assumed for reading the data.
Returns: This method return the following.
- imagedata : This returns the image data
Below examples illustrate the matplotlib.pyplot.imread() function in matplotlib.pyplot:
Example #1:
# Implementation of matplotlib functionimport numpy as npimport matplotlib.cbook as cbookimport matplotlib.image as imageimport matplotlib.pyplot as plt with cbook.get_sample_data('loggf.png') as image_file: image = plt.imread(image_file) fig, ax = plt.subplots()ax.imshow(image)ax.axis('off') plt.title('matplotlib.pyplot.imread() function Example', fontweight ="bold")plt.show() |
Output:
Example #2:
# Implementation of matplotlib functionimport numpy as npimport matplotlib.cbook as cbookimport matplotlib.image as imageimport matplotlib.pyplot as plt with cbook.get_sample_data('loggf.png') as file: im = image.imread(file) fig, ax = plt.subplots() ax.plot(np.cos(10 * np.linspace(0, 1)), '-o', ms = 15, alpha = 0.6, mfc ='green') ax.grid()fig.figimage(im, 10, 10, zorder = 3, alpha =.5) plt.title('matplotlib.pyplot.imread() function Example', fontweight ="bold")plt.show() |
