python script----BMP 2 JPG

知道了CImage类,发现其实也是一样的!

不过还是喜欢脚本,灵活,方便,简洁!

 

从今天起，我彻底的爱上了python！
今天从网上下了些图片，结果保存成的是bmp格式！！不喜欢，我想把它们转成jpg格式的，想用photoshop来着，但是那是个大家伙，我想干脆自己写个程序得了，一开始想用cximage，是我在csdn社区里看到的一个c++的库，但是，我不会c++更不喜欢类啊类的！
后来，我想到了python，搜了搜就找到了pil库，很方便的，我就写了一个简单的script！
代码如下：
=======================================================

# -*- coding:utf-8 -*-
# Python Script
# BMP2JPG.py
#-----------------------------------------------------
# TO:
#     a script used to convert BMP files in current
#     directory to JPG files and save the JPG files
#     in a new directory named JPG
#     此脚本用来把当前目录下的bmp文件转换为jpg文件
#-----------------------------------------------------

#-----------------------------------------------------
# PS:
#     to use this script you must have pil installed

#     and i don't know much about python and programming
#     maybe these is something wrong that i don't konw
#-----------------------------------------------------
 
import os, sys
import Image
filenames = os.listdir(os.curdir)
os.mkdir("JPG")
if len(filenames)>4:
    for filename in filenames:
        if filename[-4:] == ".bmp":
            Image.open(filename).save("JPG/"+filename[:-4]+".jpg")

=================================================================
程序还是有问题的，因为我在程序里创建了一个名为“JPG”的文件夹来存放转换后的jpg文件
如果在当前的目录下有jpg这个文件夹的话，系统就会出错！

由于对python还不是很熟，所以，对于错误的处理还是没有经验的，不过，应该有办法的！
这几天好好学习一哈，把程序再改改！

加了个异常处理,不知道效果
