python将图片转换为word python将图片转换为数字

1、转化为数组

-*- coding: utf-8 -*-
from PIL import Image
 from pylab import *
 #读取图片并转为数组
 im = array(Image.open("C:\\Users\\Administrator\\Desktop\\22.png"))
 #输出数组的各维度长度以及类型
 print im.shape,im.dtype
 #输出位于坐标100,100，颜色通道为r的像素值
 print im[100,100,0]
 #输出坐标100,100的rgb值
 print im[100,100]及类型
 print im.shape,im.dtype

2、 获取每一个像素值

im = im.convert("RGB")
 r,g,b = im.getpixel((10,10))

 

3、图片切割

先 pip install Pillow
from PIL import Image
def cut_pic(pic_filepath,cut_pic_filepath,index):
     u''' 裁剪图片
     :param pic_filepath 需要裁剪图片url
     :param cut_pic_filepath 裁剪后图片存储的url
     :param index 裁剪坐标字典 example index = {"left":20,"upper":20,"right":20,"lower":20 }
     :return False：裁剪失败 True ：裁剪成功
     :example cut_pic(pic_filepath,cut_pic_filepath,index)
     '''
     img = Image.open(pic_filepath)
     try :
         cropped = img.crop((index["left"], index["upper"], index["right"], index["lower"]))
         cropped.save(cut_pic_filepath)
     except Exception as e:
         print (e)
         return False
     return True
