<div>> Hi all,</div>
<div>> I'm a newer to VTK. I know that there are two VTK file formats to save</div>
<div>> objects, one is the legacy format, another is XML-based file format. For</div>
<div>> the XML-based format, different data types have different file extensions.</div>
<div>> For example, .vti for vtkImageData, .vtp for vtkPolyData, .vts for</div>
<div>> vtkStructuredGrid. However, for the legacy format, there is only one file</div>
<div>> extension (.vtk). My question is there a quick function in VTK to know the</div>
<div>> exact data type of a .vtk file?</div>
<div>></div>
<div>> Thanks,</div>
