一、windows上安装ImageMagick(参考:https://my.oschina.net/roaminlove/blog/96279)
地址:http://ftp.icm.edu.pl/pub/unix/graphics/GraphicsMagick/windows/
关于Q8,Q16(默认),Q32的说明:
  Q8表示: 8-bits per pixel quantum
  Q16表示:16-bits per pixel quantum
  Q32表示:32-bits per pixel quantum
  使用16-bit per pixel quantums在处理图片时比8-bit慢15%至50%,并须要更多的内存,处理一张1024x768像素的图片8-bit要使用3.6M内存,16-bit要使用7.2M内存,计算方法是: (5 * Quantum Depth * Rows * Columns) / 8。建议使用8,现在数码相机照的相片,每一种颜色就是8位深,3种颜色就是24位。注意事项:windows下运行,需要配置ImageMagick的安装路径,可用配置文件方式,也可配环境变量“PATH:D:\Program Files\GraphicsMagick-1.3.18-Q8”。

 

二. Linux下的安装与配置ImageMagick(Centos64、Redhat下测试成功)(参考:http://blog.csdn.net/blackonline/article/details/61195842)

1、查看所需依赖是否安装
      yum install -y gcc libpng libjpeg libpng-devel libjpeg-devel ghostscript libtiff libtiff-devel freetype freetype-devel

或:rpm -q libjpeg libjpeg-devel libpng libpng-devel freetype freetype- devel libtiff

2.下载GraphicsMagick

    wget ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/1.3/GraphicsMagick-1.3.25.tar.gz

3、新建文件夹graphicsMagick,在文件夹内解压GraphicsMagick-1.3.25.tar.gz

     tar -zxvf GraphicsMagick-1.3.25.tar.gz

4、编译

      ./configure --with-quantum-depth=8 --enable-shared

5、安装

      make

      make install

6、验证

      gm -version

7、测试,新建测试文件夹test,在测试文件夹储存一张测试图片testin.jpg,运行如下命名,查看是否成功

      gm convert -scale 100x100 testin.jpg testout.jpg

8、常用命令介绍 

      http://blog.csdn.net/cbbbc/article/details/52175559   

      http://blog.csdn.net/haima1998/article/details/73951312

 

三、下载 im4java(参考:http://blog.csdn.net/tangpengtao/article/details/9208047)

地址:http://sourceforge.net/projects/im4java/?source=directory

im4java的思路是通过线程或者进程执行graphicsmagick的命令,它的api只是为了能生成命令,而不是调用graphicsmagick的库。IM4JAVA是同时支持ImageMagick和GraphicsMagick的,这里是bool值,如果为true则使用GM,如果为false支持IM。
