ImageJ庫無法打開tiff圖像

Question

我已經編寫了下面的代碼來打開一個tiff圖像。其實我試圖在java應用程序中使用imageJ（ImagePlus）庫。但它給錯誤信息。

「的ImageJ不能打開TIFF以這種方式（4）壓縮文件」

任何幫助將不勝感激。

public class GetPixelCoordinates { 

//int y, x, tofind, col; 
/** 
* @param args the command line arguments 
* @throws IOException 
*/ 
    public static void main(String args[]) throws IOException { 
     try { 
      //read image file 

      ImagePlus img = new ImagePlus("C:\\javaCode\\TestIJ\\check_1.tiff"); 

      //write file 
      FileWriter fstream = new FileWriter("C:\\javaCode\\TestIJ\\log.txt"); 
      BufferedWriter out = new BufferedWriter(fstream); 

      //find cyan pixels 
      for (int y = 0; y < img.getHeight(); y++) { 
       for (int x = 0; x < img.getWidth(); x++) { 

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

        // Color color = new Color() 
        int redValue = c[0]; 
        int greenValue = c[1]; 
        int blueValue = c[2]; 


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

        } 
       } 
      } 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
}

TIFF圖像可以是compressed in various ways。 ImageJ只能打開some of them（另請參閱source code）。嘗試使用Bio-Formats library及其輔助類BF打開文件：

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

/* ... */ 

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