在一次工作中，需要对图片进行处理，windows自带的 画图 软件达不到需要的要求，于是便自己写了个小工具，在此分享：
首先在Python 环境安装好的情况下 ，安装PIL(Python Imaging Library)模块
下面是一些使用
#coding=utf-8
import Image
import urllib2
import StringIO
import os
#改变图片大小
def resize_img(img_path):
try:
img = Image.open(img_path)
(width,height) = img.size
new_width = 1055
# new_height = height * new_width / width
new_height = 582
out = img.resize((new_width,new_height),Image.ANTIALIAS)
ext = os.path.splitext(img_path)[1]
new_file_name = '%s%s' %('new',ext)
out.save(new_file_name,quality=95)
except Exception,e:
print e
#改变图片类型
def change_img_type(img_path):
try:
img = Image.open(img_path)
img.save('new_type.png')
except Exception,e:
print e
#处理远程图片
def handle_remote_img(img_url):
try:
request = urllib2.Request(img_url)
img_data = urllib2.urlopen(request).read()
img_buffer = StringIO.StringIO(img_data)
img = Image.open(img_buffer)
img.save('remote.jpg')
(width,height) = img.size
out = img.resize((200,height * 200 / width),Image.ANTIALIAS)
out.save('remote_small.jpg')
except Exception,e:
print e
if __name__ == '__main__':
img_path = 'boy.png'
resize_img(img_path)
# change_img_type(img_path)
# img_url = 'http://img.hb.aicdn.com/042f8a4a70239f724ff7b9fa0fc8edf18658f41022ada-WcItWE_fw554'
# handle_remote_img(img_url)
