ImageMagick及PHP的imagick扩展的安装及配置

admin

September 23, 2010 - 8 minutes read - 1699 words

在看在 ” 基于CentOS 5.5 搭建nginx +php +php-fpm+mysql高性能php平台“的1.7的时候，发现以下两个包，

wget http://blog.s135.com/soft/linux/nginx_php/imagick/ImageMagick.tar.gz wget http://pecl.php.net/get/imagick-2.3.0.tgz

不太清楚两个包的区别是什么的，在网上查了一下，注意区别如下：

imagick 是一个 PHP 的扩展，用 ImageMagick 提供的API来进行图片的创建与修改，不过这些操作已经包装到扩展imagick中去了，最终调用的是ImageMagick提供的API.

ImageMagick是一套软件系列，主要用于图片的创建、编辑以及转换等，详细的解释见ImageMagick的官方网站 http://www.imagemagick.org/，ImageMagick与GD的性能要高很多，如果是在处理大量的图片时更加能体现ImageMagick的性能。

英文原文介绍如下：

imagick is a native php extension to create and modify images using the ImageMagick API.

ImageMagick is a software suite to create, edit, and compose bitmap images.. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.

著名的图片服务提供商 Flickr 使用的是ImageMagick，还有 Yupoo、手机之家使用的也是ImageMagick。

1.安装ImageMagick

这里主要说说Linux下的安装，Windows下的安装就不说了，Windows下的安装相对简单一些，参考 http://www.imagemagick.org/script/install-source.php#windows

由于安装imagick扩展时需要依赖ImageMagick的函数库，因此必须要先安装ImageMagick

从地址ftp://ftp.imagemagick.org/pub/ImageMagick/可以找到ImageMagick的地址

[root@CentOS_Test_Server software]# wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick-6.5.3-10.tar.gz

通过命令man ImageMagick可以查看ImageMagick手册的内容，特别要注意ImageMagick中的大小写，不要写错了

2.安装PHP的扩展imagick

安装imagick扩展时需要PHP >= 5.1.3，ImageMagick >= 6.2.4

从 http://pecl.php.net/package/imagick 找到imagick的最新的stable版本

[root@CentOS_Test_Server software]# wget http://pecl.php.net/get/imagick-2.2.2.tgz

让我们来看看imagick的扩展的配置选项

[root@CentOS_Test_Server imagick-2.2.2]# ./configure –help | more

`configure’ configures this package to adapt to many kinds of systems.

Usage: ./configure [OPTION]… [VAR=VALUE]…

To assign environment variables (e.g., CC, CFLAGS…), specify them as

VAR=VALUE. See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:

-h, –help display this help and exit

–help=short display options specific to this package

–help=recursive display the short help of all the included packages

-V, –version display version information and exit

-q, –quiet, –silent do not print `checking…’ messages

–cache-file=FILE cache test results in FILE [disabled]

-C, –config-cache alias for `–cache-file=config.cache’

-n, –no-create do not create output files

–srcdir=DIR find the sources in DIR [configure dir or `..’]

Installation directories:

–prefix=PREFIX install architecture-independent files in PREFIX

[/usr/local]

–exec-prefix=EPREFIX install architecture-dependent files in EPREFIX

[PREFIX]

By default, `make install’ will install all the files in

/usr/local/bin’, /usr/local/lib’ etc. You can specify

an installation prefix other than /usr/local’ using –prefix’,

for instance `–prefix=$HOME’.

For better control, use the options below.

Fine tuning of the installation directories:

–bindir=DIR user executables [EPREFIX/bin]

–sbindir=DIR system admin executables [EPREFIX/sbin]

–libexecdir=DIR program executables [EPREFIX/libexec]

–datadir=DIR read-only architecture-independent data [PREFIX/share]

–sysconfdir=DIR read-only single-machine data [PREFIX/etc]

–sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

–localstatedir=DIR modifiable single-machine data [PREFIX/var]

–libdir=DIR object code libraries [EPREFIX/lib]

–includedir=DIR C header files [PREFIX/include]

–oldincludedir=DIR C header files for non-gcc [/usr/include]

–infodir=DIR info documentation [PREFIX/info]

–mandir=DIR man documentation [PREFIX/man]

System types:

–build=BUILD configure for building on BUILD [guessed]

–host=HOST cross-compile to build programs to run on HOST [BUILD]

–target=TARGET configure for building compilers for TARGET [HOST]

Optional Features:

–disable-FEATURE do not include FEATURE (same as –enable-FEATURE=no)

–enable-FEATURE[=ARG] include FEATURE [ARG=yes]

–enable-shared=PKGS build shared libraries default=yes

–enable-static=PKGS build static libraries default=yes

–enable-fast-install=PKGS optimize for fast installation default=yes

–disable-libtool-lock avoid locking (might break parallel builds)

Optional Packages:

–with-PACKAGE[=ARG] use PACKAGE [ARG=yes]

–without-PACKAGE do not use PACKAGE (same as –with-PACKAGE=no)

–with-libdir=NAME Look for libraries in …/NAME rather than …/lib

–with-php-config=PATH Path to php-config php-config

–with-imagick=DIR Enables the imagick extension. DIR is the prefix to Imagemagick installation directory.

–with-imagick-gm=DIR GraphicsMagick backend. NO LONGER SUPPORTED!

–with-gnu-ld assume the C compiler uses GNU ld default=no

–with-pic try to use only PIC/non-PIC objects default=use both

–with-tags=TAGS include additional configurations automatic

Some influential environment variables:

CC C compiler command

CFLAGS C compiler flags

LDFLAGS linker flags, e.g. -L if you have libraries in a

nonstandard directory

CPPFLAGS C/C++ preprocessor flags, e.g. -I if you have

headers in a nonstandard directory

CPP C preprocessor

Use these variables to override the choices made by `configure’ or to help

it to find libraries and programs with nonstandard names/locations.

./configure –with-php-config=/usr/local/webserver/php/bin/php-config –with-imagick=/usr/local/imagemagick

编译过程中如果报错，则通过ln -s把ImageMagick的so及la文件链接到/usr/lib目录下，如果不报错，则不需要做链接，我原来是由于安装包不对，导致用tar zxvf解压的时候文件解出来的不全，例如一些.h文件都没有解压出来，所以编译当然会报错了，因此我才加了下面这些链接，后来编译还是报错。

[root@CentOS_Test_Server lib]# ln -s /usr/local/imagemagick/lib/libMagickCore.so /usr/lib/libMagickCore.so

小记编译imagick扩展遇到的郁闷的问题

由于原来在目录/home/software下已经有文件imagick-2.2.2.tgz，这个文件是在vista下面下载后，通过Vmware共享给CentOS的，后来我通过wget又下载了一个，很巧的是也同样还是这个版本，文件名一模一样，因此新下载的imagick扩展自动命名为imagick-2.2.2.tgz.1，wget的下载日志“23:08:08 (35.1 KB/s) – `imagick-2.2.2.tgz.1′ saved [77212/77212]”，解压的时候解的仍然是vista下面下载的那个文件，因此导致解压的时候报错，解压出来的文件不全，因此导致编译报错，可能是与安装包的格式有关吧，参考 http://linux.chinaunix.net/bbs/thread-1026205-1-1.html，与这个有点类似吧，通过wget下载的安装包应该是不会出现这个问题的，然后rm imagick-2.2.2.tgz，mv imagick-2.2.2.tgz.1 imagick-2.2.2.tgz，tar zxvf imagick-2.2.2.tgz，解压后正常，说明是安装包的问题，然后后来的一切就都正常了。

make install也就是把编译生成的so文件拷贝到php的扩展目录下

[root@CentOS_Test_Server imagick-2.2.2]# make install

/bin/sh /home/software/imagick-2.2.2/libtool –mode=install cp ./imagick.la /home/software/imagick-2.2.2/modules

cp ./.libs/imagick.so /home/software/imagick-2.2.2/modules/imagick.so

cp ./.libs/imagick.lai /home/software/imagick-2.2.2/modules/imagick.la

PATH=”$PATH:/sbin” ldconfig -n /home/software/imagick-2.2.2/modules

———————————————————————-

Libraries have been installed in:

/home/software/imagick-2.2.2/modules

If you ever happen to want to link against installed libraries

in a given directory, LIBDIR, you must either use libtool, and

specify the full pathname of the library, or use the `-LLIBDIR’

flag during linking and do at least one of the following:

– add LIBDIR to the `LD_LIBRARY_PATH’ environment variable

during execution

– add LIBDIR to the `LD_RUN_PATH’ environment variable

during linking

– use the `-Wl,–rpath -Wl,LIBDIR’ linker flag

– have your system administrator add LIBDIR to `/etc/ld.so.conf’

See any operating system documentation about shared libraries for

more information, such as the ld(1) and ld.so(8) manual pages.

———————————————————————-

Installing shared extensions: /usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/

查看so文件是否已经生成，发现imagick.so文件已经在php的扩展目录下面了，证明已经安装成功

[root@CentOS_Test_Server imagick-2.2.2]# ll /usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/

总计 3040

-rwxr-xr-x 1 root root 172209 05-17 19:07 db4.so

-rwxr-xr-x 1 root root 517843 04-28 20:55 eaccelerator.so

-rwxr-xr-x 1 root root 748762 07-22 03:30 imagick.so

-rwxr-xr-x 1 root root 1308827 07-08 19:10 xapian.so

3.相关配置

vi /usr/local/webserver/php/etc/php.ini，加入如下的一行

extension = “imagick.so”

然后执行php -m | grep imagick，发现已经出现imagick模块了，证明imagick已经生效了

[root@CentOS_Test_Server imagick-2.2.2]# php -m | grep imagick

imagick

上面只是命令行生效了，为了让web服务器也生效，必须要重启php-fpm(我的环境是Nginx+fastcgi方式执行的php)

[root@CentOS_Test_Server imagick-2.2.2]# /usr/local/webserver/php/sbin/php-fpm restart

Shutting down php_fpm . done

Starting php_fpm done

vi index.php,输入如下的内容

phpinfo()

在浏览器执行index.php即可看到模块imagick已经生效

4.测试

PHP的imagick安装以后，提供4个PHP的图片处理类，分别是Imagick、ImagickDraw、ImagickPixel、ImagickPixelIterator，可以参考PHP的英文手册(一般指的是chm格式的手册，可以下载到本地查阅)或者在线手册( http://cn.php.net/imagick)

可以用两种方式进行调用，一种方式是直接调用/usr/local/imagemagick/bin目录下的命令，第二种方式是调用PHP的imagick扩展提供的api

测试一,通过php扩展进行调用

vi /home/htdocs/www/imagick_test1.php，输入如下的代码

header(‘Content-type: image/jpeg’);

$image = new Imagick(‘old_s.jpg’);

// If 0 is provided as a width or height parameter,

// aspect ratio is maintained

$image->thumbnailImage(100, 0);

echo $image;

然后在浏览中执行，即可看到一张100px × 80px的图片，old_s是大S的意思，也就是我是用大S的照片做的测试，在这里就不截图了，其它的例子大家看手册基本就会用了

另外可以在上述文件中的第一行加入判断模块imagick已经安装或加载的代码，extension_loaded(‘imagick’) or die(‘imagick not loaded’);

测试二,通过命令行进行调用

进入到图片所在目录

cd /home/htdocs/www

/usr/local/imagemagick/bin/convert old_s.jpg -resize 50% old_s.png

原来的图片old_s.jpg是800640，转换后生成的图片old_s.png是400320，刚好减少一半

每个命令的选项少的有几十个，多的则有上百个选项，非常复杂，功能非常的强大，参考 http://www.imagemagick.org/script/command-line-tools.php

另外，Discuz采用了ImageMagick及GD两种方式来处理图片，Discuz7.0版本有个文件Discuz_7.0.0_SC_GBK/upload/include/image.class.php,基中的方法Thumb_IM及Watermark_IM使用的就是ImageMagick，大家可以参考一下Discuz的代码。

BTW:我写这篇博客是用的笔记本电脑的电池，因为有一段时间没有用笔记本电脑的电池了，以后每月尽量充放电一次，以保持电池的容量，电池大概用了二个小时零10分钟吧，还算可以
