Hi Everyone,

 

I am creating a Dicom Image viewer.

I am using Imagej for opening uncompressed images and Loci for Compressed
images.

 

I am opening my compressed images with the help of bio-Formats.jar.

After that I convert this image to Imagej's ImagePlus object and then
displaying onto my panel.

 

Everything is successful but after display when I change a Window level or
window center with just a fraction

then image gets fully white.

 

Is there is any problem in conversion or why image is ok with window level
and window center.

Here is my code for conversion of compressed image to imagej

 

 public ImagePlus openImage(String directory, String name)

      {

            stack = null;

            try

            {

                  ////setting file name as id

                  String id = directory + name;

                  red = new ImageReader();

                  red.setId(id);

 

                  ////for reading the metadata of image

                  mdr = new MetaDataReader(red);

 

                  ////for reading the width and height of image

                  width = (short)red.getSizeX();

                  height = (short)red.getSizeY();

                  short imageCount = (short)red.getImageCount();

 

                  stack = new ImageStack(width, height);

 

                  BufferedImage bimg = null;

                  for (short i = 0; i < 1; i++)

                  {

                        bimg = red.openImage(i);

 

                        ////creating a imageplus object with bimg

                        ImagePlus imp = new ImagePlus("", bimg);

 

////for getting image processor from imageplus object

                        ImageProcessor ip = imp.getProcessor();

                        stack.addSlice("", ip, i);

                  }

                  red.close(true);

            }

            catch (Exception e)

            {

                  return null;

            }

 

////create a new image plus object with above stack

//and return a new image Plus object

            return new ImagePlus(name, stack);

      }

 

 

Thanks in advance
