Matplotlib.pyplot.imread Example

Matplotlib.pyplot.imread Example. The values in the array are rgb values (y, x, color).the array is a standard numpy array, so you can use argwhere and argmax to get the required information (argmax finds first occurrence of 1 or true in the boolean array of 0 and 1 or false and true).you desired distances are the x coordinates:. Read an image from a file into an array.

As you can see the pie chart draws one piece (called a wedge) for each value in the array (in this case [35, 25, 25, 15]). Import matplotlib.pyplot as plt my_img = plt.imread ('my_img.tiff') my_clipped_img = my_img [s1:s2,r1:r2] the latter has the benefit of not creating a full sized array, but just of the size you want.
