设置一个clip_patch
下面是官网示例https://matplotlib.org/stable/ga ... -image-clip-path-py
import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.cbook as cbook
with cbook.get_sample_data('grace_hopper.jpg') as image_file:
image = plt.imread(image_file)
fig, ax = plt.subplots()
im = ax.imshow(image)
patch = patches.Circle((260, 200), radius=200, transform=ax.transData)
im.set_clip_path(patch)
ax.axis('off')
plt.show() |
