Question

我写了下面的代码来打开一个tiff图像。其实我试图在java应用程序中使用imageJ（ImagePlus）库。但是它给出了错误信息。

＆＃34; ImageJ无法打开以这种方式压缩的TIFF文件（4）＆＃34;

非常感谢任何帮助。

                    int c[] = img.getPixel(x,y);

                     if (redValue < 30 &&greenValue >= 225 && blueValue >= 225) {
                         out.write("CyanPixel found at=" + x + "," + y);
                         out.newLine();

        }
    }

TIFF图片可以是compressed in various ways。 ImageJ只能打开some of them（另请参阅source code）。尝试使用Bio-Formats library及其帮助程序类BF打开文件：

import ij.ImagePlus;
import loci.plugins.BF;

/* ... */

ImagePlus imp = BF.openImagePlus("path/to/your/image.tiff");

ImageJ库无法打开tiff图像
