第一步：在python27資料夾下建立一個mytool資料夾，然後建立showpicture.py

#coding:utf-8 
'''
python showpicture.py --image *.png
'''

from PIL import Image  
from pylab import *  
from PCV.tools import imtools
import argparse
import cv2  
ap = argparse.ArgumentParser()
ap.add_argument("-i","--image",required=True,help="Path to the image")
args = vars(ap.parse_args())
 
from matplotlib.font_manager import FontProperties  
font = FontProperties(fname=r"C:/Windows/Fonts/msyh.ttc", size=14)  
#im = array(Image.open('C:/pytm/pic/ceshi.jpg').convert('L'))  
im1 = array(Image.open(args["image"]))
    
subplot()  
axis('off')   
title(u'Picture', fontproperties=font)  
imshow(im1)  

  
show()  
 

（假設在python27/mytool下有一個trex.png影象）

python showpicture.py --image trex.png

第二版：

直接在eclipse上執行的：

#coding:utf-8   
''''' 
python showpicture.py --image *.png 
'''  
  
from PIL import Image    
from pylab import *    
  
   

from matplotlib.font_manager import FontProperties    
font = FontProperties(fname=r"C:/Windows/Fonts/msyh.ttc", size=14)    

im1 = array(Image.open('d:/0000/5/5.jpg'))        
subplot() 
gray()   
axis('off')     
title(u'Picture', fontproperties=font)    
imshow(im1)    
  
    
show()
