PIL安装记录,编译支持jpeg png

 

PIL是python理想的图片处理module,但是想要良好的支持各种图片,还需要检查一下几步,否则会提示:IOError: decoder jpeg not available之类的。


我的环境:Linux mint 11 amd64 / Python2.7


第一步:安装zlib png freetype   jpeg

  • install zlib (ubuntu 官方源没有zlib,别想apt-get了)

      下载zlib,(zlib.net已墙,可以去SF.net),url: http://sourceforge.net/projects/libpng/files/zlib/1.2.5/zlib-1.2.5.tar.gz/download?use_mirror=superb-dca2

 

      shell:

$ tar -xvzf zlib-1.2.5.tar.gz
$ cd zlib-1.2.5
$ ./configure --prefix=/usr/local
$ make
$ sudo make install

  • install png(忘记apt-get吧)
shell:
$ wget ftp://ftp.simplesystems.org/pub/libpng/png/src/libpng-1.5.6.tar.gz (如果文件不存在就浏览 /src/目录查找一下最新版)
$ tar -xvzf libpng-1.5.6.tar.gz
$ cd libpng-1.5.6
$ ./configure --prefix=/usr/local
$ make
$ sudo make install
 
  • install freetype (忘记apt-get吧)

     shell:

$ wget http://nchc.dl.sourceforge.net/project/freetype/freetype2/2.4.7/freetype-2.4.7.tar.gz
$ tar -xvzf freetype-2.4.7.tar.gz
$ cd freetype-2.4.7/
$ ./configure --prefix=/usr/local
$ make
$ make install
 
  • install jpeg (忘记apt-get吧)

    shell:

$ wget http://www.ijg.org/files/jpegsrc.v8c.tar.gz
$ tar -xvzf jpegsrc.v8c.tar.gz
$ cd jpeg-8c/
$ ./configure --prefix=/usr/local
$ make
$ sudo make install
 

 

 

第二步:安装需要的 devel库(现在是想起apt-get的时候了)

 

shell:
$ sudo apt-get install libjpeg8-dev

$ sudo apt-get install libpng12-dev

$ sudo apt-get install libfreetype6-dev

$ sudo apt-get install zlib1g-dev

 

 

第三步:安装 PIL( Python Imaging Library

 

shell 写道
$ wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz
$ tar -xvzf Imaging-1.1.7.tar.gz
$ cd Imaging-1.1.7/

   

修改setup.py文件:
$ nano setup.py

修改如下:
JPEG_ROOT = "/usr/local/lib"
ZLIB_ROOT = "/usr/local/lib"
FREETYPE_ROOT = "/usr/local/lib"

 

   检查是否支持:

$ python setup.py build_ext -i
running build_ext
--------------------------------------------------------------------
PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version 1.1.7
platform linux2 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53)
[GCC 4.5.2]
--------------------------------------------------------------------
*** TKINTER support not available
--- JPEG support available         -----------------------> OK!
--- ZLIB (PNG/ZIP) support available -----------------------> OK!
--- FREETYPE2 support available ----------------------->  OK!
*** LITTLECMS support not available
--------------------------------------------------------------------
To add a missing option, make sure you have the required
library, and set the corresponding ROOT variable in the
setup.py script.

To check the build, run the selftest.py script.

 

   正式安装:

$ python setup.py build
$ sudo python setup.py install

 

最后一步:验证

 

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import Image
picPath = '~/images/1212.jpg'

im = Image.open(picPath)
print im.getbbox()

 

输出结果图片尺寸:
(0, 0, 600, 715)
 

 

yeah,搞定!
