python 图像处理(从安装Pillow开始)

时间:2021-07-31 09:06:44

python2.x及以下用的是PIL(图像处理库是 PIL(Python Image Library)),最新版本是 1.1.7  可在http://www.pythonware.com/products/pil/index.htm 下载和学习。

不过从该网站可看出它不支持python3.x

Pillow由PIL而来(支持3.x),所以该导入该库使用import PIL

由于本人用的是python 3.4 所以下载的Pillow

关于下载第三方库,有三种方法,之前用的都是

第一种方法

  1 下载第三方包,解压

  2 在命令提示符里输入cmd,然后用cd进入到第三方包的路径下

  3 输入python setup.py build

  4 输入python setup.py install

效率低下

故这次打算安装pip和easy_installer工具,通过代码就可以安装,

安装可参考:http://heipark.iteye.com/blog/1916758 或者http://blog.chinaunix.net/uid-12014716-id-3859827.html(内有官网地址)

除此之外在相应的官网也提供详细的安装教程(Mac OS的话真是快很多)

easy_installer简便安装:

Windows (simplified) (官网说明)

For Windows without PowerShell 3 or for installation without a command-line, download ez_setup.py using your preferred web browser or other technique and “run” that file.

保存本地后运行就在安装了,

pip安装 法1:下载解压,cd切换到pip的目录,找到setup.py文件,然后输入python setup.py install

最后显示

Installed d:\python34\lib\site-packages\pip-7.1.2
Processing dependencies for pip==7.1.2
Finished processing dependencies for pip==7.1.2

法2(推荐):安装完easy_install 后就可以执行这样的命令了

C:\Users\Administrator>easy_install pip
Searching for pip
Best match: pip 7.1.
Processing pip-7.1.-py3..egg
pip 7.1. is already the active version in easy-install.pth
Installing pip-script.py script to D:\python34\Scripts
Installing pip.exe script to D:\python34\Scripts
Installing pip.exe.manifest script to D:\python34\Scripts
Installing pip3-script.py script to D:\python34\Scripts
Installing pip3.exe script to D:\python34\Scripts
Installing pip3.exe.manifest script to D:\python34\Scripts
Installing pip3.-script.py script to D:\python34\Scripts
Installing pip3..exe script to D:\python34\Scripts
Installing pip3..exe.manifest script to D:\python34\Scripts Using d:\python34\lib\site-packages\pip-7.1.-py3..egg
Processing dependencies for pip
Finished processing dependencies for pip

那么接下来就是pip的使用(可参考http://www.th7.cn/Program/Python/201410/289949.shtml)

C:\Users\Administrator>pip install Pillow
Collecting Pillow
Downloading Pillow-2.9.0-cp34-none-win32.whl (1.2MB)
100% |████████████████████████████████|
Installing collected packages: Pillow
Successfully installed Pillow-2.9.0

那么pillow就安装成功了

在Pillow的官网教程也有教程http://pillow.readthedocs.org/installation.html 多种安装方式可参考

接下来

C:\Users\Administrator>python
Python 3.4.2 (v3.4.2:ab2c023a9
Type "help", "copyright", "cre
>>> 2
2
>>> from PIL import Image
>>>

没报错,说明安装成功

接下来可在http://pillow.readthedocs.org/index.html开始学习,或参考他人blog 后面将继续出图像处理的例子~
