How we can convert a dicom file(.dcm) to a jpeg image using java? Here is my code:
import java.io.File; import java.io.IOException; import org.dcm4che2.tool.dcm2jpg.Dcm2Jpg; public class MainClass { public static void main(String[] args) throws IOException{ Dcm2Jpg conv = new Dcm2Jpg(); conv.convert(new File("C:\\Users\\lijo.joseph\\Desktop\\Dicom\\IM-0001-0001.dcm"), new File("C:\\Users\\lijo.joseph\\Desktop\\Dicom\\IM-0001-0001.jpg")); } }
and i am getting the following error while running the project
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException at MainClass.main(MainClass.java:7) Caused by: java.lang.ClassNotFoundException: org.apache.commons.cli.ParseException at java.net.URLClassLoader$1.run(URLClassLoader.java:372) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:360) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 1 more
please help and thanks in advance
Here is the link Converting DICOM to JPEG using dcm4che 2
Following is my code which works perfectly.I have placed it with imports so it might be use-full.
import java.awt.image.BufferedImage; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.util.Iterator; import javax.imageio.ImageIO; import javax.imageio.ImageReader; import javax.imageio.stream.ImageInputStream; import org.dcm4che2.imageio.plugins.dcm.DicomImageReadParam; import com.sun.image.codec.jpeg.JPEGCodec; import com.sun.image.codec.jpeg.JPEGImageEncoder; public class Examplke1 { static BufferedImage myJpegImage=null; public static void main(String[] args) { File file = new File("test5/12840.dcm"); Iterator iterator =ImageIO.getImageReadersByFormatName("DICOM"); while (iterator.hasNext()) { ImageReader imageReader = (ImageReader) iterator.next(); DicomImageReadParam dicomImageReadParam = (DicomImageReadParam) imageReader.getDefaultReadParam(); try { ImageInputStream iis = ImageIO.createImageInputStream(file); imageReader.setInput(iis,false); myJpegImage = imageReader.read(0, dicomImageReadParam); iis.close(); if(myJpegImage == null){ System.out.println("Could not read image!!"); } } catch (IOException e) { e.printStackTrace(); } File file2 = new File("/test.jpg"); try { OutputStream outputStream = new BufferedOutputStream(new FileOutputStream(file2)); JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(outputStream); encoder.encode(myJpegImage); outputStream.close(); } catch (IOException e) { e.printStackTrace(); } System.out.println("Completed"); } } }

If you don't want to use direct Dcm2Jpg.java file then you can include below jar file.
dcm4che-tool-dcm2jpg-2.0.23.jar
In this jar you can import org.dcm4che2.tool.dcm2jpg.Dcm2Jpg this java file
