如何删除图片中的填充？

Question

我只想在没有填充和轴的情况下保存图片 以下是代码：

#-*- coding:utf-8 -*-
import SimpleITK as sitk
import numpy as np
import matplotlib.pyplot as plt

url = r"G:to\my\filename.mha"
path = r'F:\image\s.png'
image = sitk.ReadImage(url)

max_index = image.GetDepth()
max_width = image.GetWidth()
max_height = image.GetHeight()
print(max_index,max_width,max_height)


# As list of 2D numpy arrays which cannot be modified (no data copied)
xxx = sitk.GetArrayViewFromImage(image)[75,:,:]
zzz = plt.imshow(xxx,cmap = 'gray')
plt.savefig(path)
plt.show()

然后我得到：

从这里接受我的回答：How to completely remove the white space around a scatterplot?

用以下代码替换最后三行：

fig,ax = plt.subplots(1)

fig.subplots_adjust(left=0,right=1,bottom=0,top=1)

ax.imshow(xxx)

ax.axis('tight')
ax.axis('off')
plt.savefig(path)
plt.show()
