ImageMagic for windows

1、安裝ImageMagick-6.2.6-8-Q16-windows-dll.exe

2、把安裝目錄下所有的dll文件copy到c:/windows/system32目錄下，以便調用dll。

3、解壓jmagick-6.2.6-win.zip，把q16/jmagick.dll copy 到c:/windows/system32目錄下。

4、把jar/jmagick.jar，q16/jmagick.dll copy 到jre的bin中(jdk的bin/lib中)。

5、利用jar/jmagick.jar進行java 開發。

如下是一些例子代碼：

JMagickScale.java 实现图片缩略图

//reading image
ImageInfo info = new ImageInfo("c:/image4.bmp");
MagickImage image = new MagickImage(info);

//resize image
MagickImage scaleImg = image.scaleImage(95, 80);

//write image to file
scaleImg.setFileName("c:/MyFile4.bmp");
scaleImg.writeImage(info);
}
}
JMagickTest.java 实现图片的各种操作示例,如旋转,加边框，设置背景，提升质量，加盖文字说明等等...

Is there a possibility that there are other versions of ImageMagick
libraries? Problem such as this can be a result of linking to the wrong
version of ImageMagick.

problem in executing jmagic in windows2000

Subject: problem in executing jmagic in windows2000

hello,

i downloaded ImageMagic in to my system. i am having windows 2000
instatlled on my system, it worked fine. and then i download JMagick. i
kept the jmagick.dll file at c:/winnt/System32 and at
c:/j2sdk1.4.1_01/jre/bin.
and libray at
c:/j2sdk1.4.1_01/jre/lib/ext/; and set my classpath to jar file. now
the problem is if i tryed to compile it it compiled without any error.
when i tried to execute the file it guve errirm

"The procedure entry point entry DestroyMagickInfo could not be located in the dynamic link library CORE_RL_magick"

Then i changed to another system where windows xp is installed and
there i found the java file is compiled and when i tried to execute it
. then it generated one *.log file. the log file is as follows

An unexpected exc eption has been detected in native code outside the VM.

i found that the error is coming at the line

MagickImage image= new MagickImage(infos);

why i am getting this error . what i need to be done inorder to use jmagick in both of my systems. please anyone help me.

i am really in need of solution for this because i am working in the
project related to images. where i need to take two images randomly and
create one final gif image.
Thanking you in advance.

现在web应用经常会用到缩略图。然后一旦生成的缩略图小于100px * 100px,一些常用的java包，生成的图片确实有点惨不忍睹。

研究了半天才研究出来，希望能让刚用到的朋友有点帮助。

现在介绍使用Jmagick的使用，可以生成质量很好的缩略图，当然还有其他很多图像处理的方法。

首先jmagick（http://www.yeo.id.au/jmagick/）是ImageMagick（http://www.imagemagick.org/）的java 应用的接口。所以要先安装ImageMagick应用程序，你的java应用才能使用,在主页上你可以轻松找到下载的链接。

1。下载jmagick,imagemagick

2.安装ImageMagick，网站上有安装方法（windows,unnix）,我只在win上做了安装，安装以后把安装目录下所有的dll文件copy到windows/system32/目录下。

3。下载的jmagick包含jmagick.jar,jmagick.dll文件，jmagick.dll需要copy到windows/system32/目录下。

4。web应用如果部署到tomcat下，那么最好在catalina.bat文件中改变如下设置

set
J***A_OPTS=%J***A_OPTS% -Xms256M -Xmx768M -XX:MaxPermSize=128M
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file="${catalina.base}/conf/logging.properties"

避免heap溢出的问题，参数看你自己的机器而定。（ -Xms256M -Xmx768M -XX:MaxPermSize=128M ）

5。还要注意如果部署到web应用，你在使用的class里面需要

System.setProperty("jmagick.systemclassloader","no");

要不然会报出UnsatisfiedLinkError: no JMagick in java.library.path.

实例如下：

public void resize(int w, int h) throws IOException {

try {
// Resize
System.setProperty("jmagick.systemclassloader","no");
ImageInfo info = new ImageInfo(sourceFileName);
MagickImage image = new MagickImage(info);
MagickImage scaled = image.scaleImage(w, h);//小图片文件的大小.
scaled.setFileName(destFile);
scaled.writeImage(info);

} catch(MagickApiException ex) {
System.out.println(ex);

} catch(MagickException ex) {
System.out.println(ex);
}
}
