 转换tif文件为图像文件可以使用JAI,jimi等包来处理

jimi处理一份39页的tif文件生成png并缩小,使用14秒。
JAI处理同一份文件却用了近60秒。(因该是偶技术问题造成的):-)

jimi处理的主要源码:

JimiCanvas jCanvas = new JimiCanvas();    
jCanvas.setImagePath(filepath);    
// 这里得到的就是tiff文件中第一页普通的Image对象了    
Image image = jCanvas.getImage();    
// 在这个文件中生成缩略图    
   
process(image);    
// 如果多于一页,循环取出    
while (jCanvas.hasNextImage()) {    
    jCanvas.nextImage();    
    image = jCanvas.getImage();    
    process(image);    
}    
   
public static void process(Image image) {    
    double width = (double) image.getWidth(null);    
    double height = (double) image.getHeight(null);    
    // 宽,高各缩小一半    
    int iWidth = (int) (width * 0.5);    
    int iHeight = (int) (height * 0.5);    
    // 用像生成其它图像文件一样的方式生成缩略图    
    BufferedImage bi = new BufferedImage(iWidth, iHeight, BufferedImage.TYPE_INT_RGB);    
    bi.getGraphics().drawImage(image, 0, 0, iWidth, iHeight, null);    
    // 输出BufferedImage    
}

JIRAAtlassian 公司开发的一款商业问题跟踪工具(开源项目经过申请可以免费使用,须提交源代码),可以对各种类型的问题进行跟踪管理,包括缺陷、需求变更、评审记录等。

安装及破解过程(MYSQL):

  • 下载atlassian-jira-enterprise-3.6.3-standalone.zip版本,其中已经包括tomcat5.x服务器
  • 下载mysql,偶使用的是mysql-5.0.22-win32解压版
  • 下载mysql jdbc驱动,JIRA默认使用的是hsql。网上有教程说要使用mysql-connector-java-3.1.12-bin.jar版本,偶本机正好有这个版本,没去试别的版本的jdbc驱动会不会出问题
  • 下载jira-jars-tomcat5.zip
  • 确保JDK1.5环境看安成功,在CMD下java -version试试 :)
  • 打开atlassian-jira-enterprise-3.6.3-standalone\atlassian-jira\WEB- INF\classes\entityengine.xml,搜索field-type-name,修改为field-type-name="mysql"
  • 将mysql-connector-java-3.1.12-bin.jar拷贝到atlassian-jira-enterprise-3.6.3-standalone\common\lib
  • 将jira-jars-tomcat5.zip拷贝到atlassian-jira-enterprise-3.6.3-standalone\common\lib
  • 修改atlassian-jira-enterprise-3.6.3-standalone\conf\server.xml,将下面大段修改为:
<RESOURCE name="jdbc/JiraDS" type="javax.sql.DataSource" password="" username="root"  
url="jdbc:mysql://localhost/jiradbautoReconnect=true&useUnicode=true&characterEncoding=UTF8&mysqlEncoding=utf8" 
maxActive="20" timeBetweenEvictionRunsMillis="5000" minEvictableIdleTimeMillis="4000" 
driverClassName="com.mysql.jdbc.Driver" auth="Container" />
  • 运行安装,打开 http://localhost:8080 进行安装
