解压缩PackBits时的Apache-Commons Sanselan AIOOBE

Question

尝试使用Apache-Commons Sanselan加载以PackBits压缩压缩的ArrayIndexOutOfBoundsException时的开箱即用的TIFF.

代码：

import org.apache.sanselan.*;

public class TIFFHandler {
    public static Image loadTIFF(String fileName) throws ImageReadException, IOException {
        File imageFile = new File(fileName);
        BufferedImage bi = Sanselan.getBufferedImage(imageFile);
        return bi;
    }

    public static void main(String[] args) throws IOException, ImageReadException {
        String TIFFFILE = "test_image.tif";
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        JPanel panel = new JPanel();
        BufferedImage bi = (BufferedImage) loadTIFF(TIFFFILE);
        ImageIcon ii = new ImageIcon(bi);
        JLabel lbl = new JLabel(ii);
        panel.add(lbl);
        frame.setVisible(true);
    }
}

堆栈跟踪：

我已经尝试过对这个问题进行分析，但我认为lost...any方向会很有帮助。TIFF图像在a**中是一种痛苦。

您可以从Apache快照存储库中尝试Commons Imaging的更新版本。Javadoc还没有上线，你必须通过checking out the code from SVN和运行mvn javadoc:javadoc来构建它。

如果您发现更多问题或想要提出改进建议，可以将它们提交到JIRA。此外，如果您对API的使用有疑问，开发人员也会很乐意为您提供帮助。他们在mailing list上等你。
