CentOS6下安装GraphicsMagick过程记录
GraphicsMagick号称图像处理领域的瑞士军刀。 短小精悍的代码却提供了一个鲁棒、高效的工具和库集合，来处理图像的读取、写入和操作，支持超过88种图像格式，包括重要的DPX、GIF、JPEG、JPEG-2000、PNG、PDF、PNM和TIFF。
通过使用OpenMP可是利用多线程进行图片处理，增强了通过扩展CPU提高处理能力。GraphicsMagick可以再绝大多数的平台上使用，Linux、Mac、Windows都没有问题。
GraphicsMagick支持大图片的处理，并且已经做过GB级别的图像处理实验。GraphicsMagick能够动态的生成图片，特别适用于互联网的应用。可以用来处理调整尺寸、旋转、加亮、颜色调整、增加特效等方面。GaphicsMagick不仅支持命令行的模式，同时也支持C、C++、Perl、PHP、Tcl、Ruby等的调用。事实上，GraphicsMagick是从 ImageMagick 5.5.2 分支出来的，但是现在他变得更稳定和优秀。
GraphicsMagick官网：http://www.graphicsmagick.org/index.html 目前最新版本为 1.3.26
安装建议：
先解压GraphicsMagick-1.3.26.tar.gz包 ./configure 检查png与jpg的支持情况，如不支持，请安装相应的图片库之后再安装GM服务。
安装一些基础包：
yum install libtool* libpng.x86_64 libpng-devel.x86_64 libpng-static.x86_64安装常见图片库jpeg及png
建立jpeg安装目录
mkdir /usr/local/jpeg6
mkdir /usr/local/jpeg6/bin
mkdir /usr/local/jpeg6/include
mkdir /usr/local/jpeg6/lib
mkdir /usr/local/jpeg6/man
mkdir /usr/local/jpeg6/man/man1
解压安装jpeg
tar xvf jpegsrc.v6b.tar.gz
cd jpeg-6b/
cp /usr/share/libtool/config/config.sub .
cp /usr/share/libtool/config/config.guess .
./configure --prefix=/usr/local/jpeg6/ --enable-shared --enable-static
make
make install64位系统以上两个cp务必执行，否则会报错
make: ./libtool：命令未找到
make: * [jcapimin.lo] 错误 127
安装libpng库
tar xvf libpng-1.4.12.tar.gz
cd libpng-1.4.12
./configure --prefix=/usr/local/png --enable-shared
make
make install安装GraphicsMagick
tar xvf GraphicsMagick-1.3.26.tar.gz
cd GraphicsMagick-1.3.26
./configure --prefix=/usr/local/graphicsMagick CPPFLAGS='-I/usr/local/png/include -I/usr/local/jpeg6/include' LDFLAGS='-L/usr/local/png/lib -L/usr/local/jpeg6/lib' --enable-shared
make
make install添加环境变量
vim /etc/profile
IM4JAVA_TOOLPATH=/usr/local/graphicsMagick/bin
export IM4JAVA_TOOLPATH
soure /etc/profile运行gm --version会显示版本信息及支持那些图片库等信息：
[root@waibao_121_180 tmp]# gm -version

GraphicsMagick常用方法
显示图像文件详细信息
identify a.jpg2.更改当前目录下*.jpg的尺寸大小，并保存于目录.thumb里面
gm mogrify -output-directory .thumbs -resize 320×200 *.jpg将三幅图像和并为一副图像
montage -mode concatenate -tile 3×1 image1.ppm image2.ppm image3.ppm concatenated.miff显示图像
display ‘vid:*.jpg’格式转换
convert a.bmp a.jpg
gm convert a.bmp a.pdf（转换为pdf)调整图像dpi和大小
convert -density 288 -geometry 25% image.gif image.gif（缩小为原先的1／4，并且dpi为288）
gm convert -resize 640×480 image.gif image.gif（转换为640×480的图像)
在图像上添加文字
convert -font Arial -fill blue -pointsize 18 -draw “text 10,10 ‘your text here'” test.tif test.png
从gif文件中抽取第一帧
convert “Image.gif[0]” first.gif
建立gif图像
convert -delay 20 frame*.gif animation.gif
gm convert -loop 50 frame*.gif animation.gif
（让动画循环50次）
gm convert -delay 20 frame1.gif -delay 10 frame2.gif -delay 5 frame3.gif animation.gif
（对每一帧手动指定延时）
截屏
import a.jpg
用鼠标点击所要截取的窗口，或者选择截屏区域，保存为a.jpg
gm import -frame a.jpg
保留窗口的边框
