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。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
}
JIRA是 Atlassian 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。
