Description

Hi. I am reading JPEG image file and using this library to convert it to BMP format. Resultant bitmap file has wrong color comparing to original file. Below is the code :

 

    ArrayList<File> files = new ArrayList<File>();
    files.add(new File("./files/25606_200x200.jpg"));
    files.add(new File("./files/91691-01.jpg"));
    for (File file : files)    
    {
      try
      {
        //File trgFile = ImageConverter.convert(file, "bmp");
        final BufferedImage bi = Imaging.getBufferedImage(file);        final File dstFile = new File(file .getAbsolutePath() + ".bmp");        Imaging.writeImage(bi, dstFile, ImageFormats.BMP);        System.out.println(dstFile.getName() + " has been converted successfully.");        
      }
      catch (Exception e)
      {
        e.printStackTrace();
      }        
    }

 

Image "25606_200x200.jpg.bmp" has the wrong color depth,  image "91691-01.jpg.bmp" has the right color depth but wrong color mapping (maybe the embedded ICC-Profile is the cause here).
