最近项目中需要用到图片的一些特殊处理——比如:根据用户请求生成任意尺寸的图像。经过一些资料的查找,最终选用了php_imagick。利用ImageMagick,你可以根据web应用程序的需要动态生成图片, 还可以对一个(或一组)图片进行改变大小、旋转、锐化、减色或增加特效等操作,并将操作的结果以相同格式或其它格式保存。本节我们就来介绍一下如何在windows下安装php_imagick拓展。

1. 下载 Download ImageMagick

#下载页面:

http://www.imagemagick.org/script/binary-releases.php#windows

#直接下载:

http://www.imagemagick.org/download/binaries/ImageMagick-6.6.3-0-Q16-windows-dll.exe

2. 安装 Install ImageMagick

安装路径随意,我的安装是:

D:\WampServer\bin\ImageMagick-6.6.3-Q16

3. 测试 Testing the Installation

如果不加入环境变量的话,可以先下面方式测试:
Open the command prompt (Run->”CMD”->ENTER) and type in convert and press enter. You should see the help parameters of convert

cd D:\WampServer\bin\ImageMagick-6.6.3-Q16 # 回车
D:\WampServer\bin\ImageMagick-6.6.3-Q16>convert
Version: ImageMagick 6.6.3-0 2010-07-01 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2010 ImageMagick Studio LLC
Features: OpenMP

Usage: Magick [options ...] file [ [options ...] file ...] [options ...] file

Image Settings:
  -adjoin              join images into a single multi-image file
  -affine matrix       affine transform matrix
  -alpha option        activate, deactivate, reset, or set the alpha channel
  -antialias           remove pixel-aliasing
  -authenticate password
                       decipher image with this password

  -background color    background color
  -bias value          add bias when convolving an image
  -black-point-compensation

  -blue-primary point  chromaticity blue primary point
  -bordercolor color   border color
  -caption string      assign a caption to an image
.......
......
......

加入环境变量,方便以后使用(我的是WIndows7 系统):
我的电脑-》右键属性-》高级系统设置-》高级-》环境变量-》系统变量-》
-》找到Path, 点击编辑加入:

D:\WampServer\bin\ImageMagick-6.6.3-Q16;

加入完成之后,可以直接在命令行(CMD)使用convert了。

4. 下载DLL Downloading the php_Imagick.dll

Again the version problem, well if you are using PHP 5.2.x this is where you will get your dll.

我使用的是 (php5.2.9-2):php_imagick_dyn-Q16.dll

dyn = dynamic, st = static, q16 = 16 bit, q8= 8 bit. This should match your downloaded version of course. If you downloaded q16 dynamic library, your file will be php_imagick_dyn-Q16.dll

If you are using PHP 5.3.x, this is your location to download.

5. 编辑 PHP.ini

下载的php_imagick_dyn-Q16.dll保存到

D:\WampServer\bin\php\php5.2.9-2\ext\

然后编辑 PHP.ini
找到dll这里,加入下面的最后一行:

;extension=php_sybase_ct.dll
;extension=php_tidy.dll
;extension=php_xmlrpc.dll
;extension=php_xsl.dll
;extension=php_zip.dll
extension=php_imagick.dll

6. 重启Wamp

7. 通过查看phpinfo();

如果有imagick项应该成功了

8. 小测试

$im = new imagick( 'a.jpg' );
// resize by 200 width and keep the ratio
$im->thumbnailImage( 200, 0);
// write to disk
$im->writeImage( 'a_thumbnail.jpg' );

好了,完成了。
