<span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">Hi Vtk users:</span><div style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">
<br></div><div style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">I used Itk imageFileReader to read an image file and (.vtk) and obtained image informations well.It displayed x dimensions only as I have written codes to get dimensions along x direction only. ImageIObase class propose to use <font color="#ff0000">std::vector< SizeValueType > m_Dimensions(); </font>to get pixels alng x,y,z directions.As I am new comer to IUtk Please help me write 3D array to get dimensions.</div>
