How does imshow handle the alpha channel with an M x N x 4 input?(Matplotlib)
Let's take an example to see how imshow() handles the alpha channel with an M×N×4 input.
Steps
- Set the figure size and adjust the padding between and around the subplots.
- Return a new array of given shape and type, filled with 1's.
- Handle the alpha channel.
- Display the data as an image, i.e., on a 2D regular raster.
- To display the figure, use show() method.
Example
import numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True d = np.ones((100, 100, 4), dtype=np.uint8)*255 d[:, :, 1] = np.linspace(0, 255, num=100) plt.imshow(d) plt.show()
