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 function import numpy as np import matplotlib.cbook as cbook import matplotlib.image as image import 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 function import numpy as np import matplotlib.cbook as cbook import matplotlib.image as image import 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() |
Output:
