Need help for Dicom image compression using dcm4che in java

[Vinayak Gaikwad]

hello,

i am vinayak ,

I am working on image compression of dicom images,for that i using dcm4che library.

in below code i have created dicom reader. to read dicom file. i got reader successfully .

String resource="D:\\CT_Head_Facial Bone 3D\\IM1";

DicomImageReader reader =  createImageReader(resource);

BufferedImage bi = readRawBufferedImage(reader, 1);

DicomStreamMetaData newMeta = copyMeta(reader, UID.JPEG2000LosslessOnly);

IIOImage iioimage = new IIOImage(bi, null, null);e here...

but at the time of writing image in to writer, 

ImageWriter writer = new DicomImageWriterSpi().createWriterInstance();

//ImageWriter imageWriterFactory=ImageWriterFactory.getInstance().getWriterForTransferSyntax("1.2.840.10008.1.2.4.90");

writer.setOutput(imageOutput);

writer.write(newMeta, iioimage, null);

writer.prepareWriteSequence(newMeta);

writer.writeToSequence(iioimage,null);

It showing error.

I have included all library dcm4che, jai image, jai_codec ,jai_core.

org.dcm4che2.data.ConfigurationError: No Image Writer of class com.sun.media.imageioimpl.plugins.jpeg2000.J2KImageWriterCodecLib available for format:jpeg2000

For resolve problem jpeg2000 use dcm4che3 version 3.3.8.
My code for display image in dcm4che3 is folllowing :

public BufferedImage readImage(  File input, int index) throws IOException{

     Iterator<ImageReader> iter = ImageIO.getImageReadersByFormatName("DICOM");
    DicomImageReader readers = (DicomImageReader) iter.next();
   
   
   
     DicomImageReadParam   param1 =  (DicomImageReadParam) readers.getDefaultReadParam();
     
     
     ImageInputStream iis = ImageIO.createImageInputStream(input);

             readers.setInput(iis, false);
     
       BufferedImage image =readers.read(index,param1);
   readers.dispose();
    return image;
}
