<p style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px">I am trying to develop an application in Java, using VTK to visualize DICOM files read from a directory, using a vtkImageViewer2 object to visualize. Below is the code segment that
 I try to execute:<br>

<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px">
vtkDICOMImageReader reader = new vtkDICOMImageReader();<br>
reader.SetDirectoryName("~/<wbr>DICOM/abdomen_bt/3");<br>
reader.Update();<br>
<br>
vtkImageViewer2 imageViewer2 = new vtkImageViewer2();<br>
imageViewer2.<wbr>SetInputConnection(reader.<wbr>GetOutputPort());<br>
<br>
vtkRenderWindowInteractor renderWindowInteractor = new vtkRenderWindowInteractor();<br>
<br>
imageViewer2.SetupInteractor(<wbr>renderWindowInteractor);<br>
<br>
imageViewer2.Render();<br>
imageViewer2.GetRenderer().<wbr>ResetCamera();<br>
renderWindowInteractor.Start()<wbr>;<br>
imageViewer2.Render();</div>

<br>
</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px">
My problem is that, this code segment renders an empty screen. But when I convert the same code segment to C++, the window renders the DICOM image successfully.</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px">
<br>
</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px">
The path to the DICOM directory is valid, and DICOM files are not compressed (180 of them), and I am using VTK 7.1.0.<br>
<br>
What might be the problem? Any help will be appreciated.<br>
<br>
Thank you.</div><span class="HOEnZb"><font color="#888888">
