The gdcmviewer is a simple tool that show how to use vtkGDCMImageReader. The class that use gdcm to make a layer to VTK. gdcmviewer is basically only just a wrapper around VTK/GDCM.

This tool is meant for testing integration of GDCM in VTK. You should see it as a demo tool. It does compile with VTK ranging from 4.2 to 5.10, but only with VTK 5.2 (or above) can play with the widgets (as described below).

Simple Usage

For now gdcmviewer should be started from a command line prompt. The next argument should be the name of the DICOM file you wish to read. For instance:

$ gdcmviewer -V 012345.002.050.dcm

gdcmviewer will try to read your file, and then print the vtk information associated with this file. Basically what kind of image you are looking at.

· ScalarType is the DICOM Real World Value type

· Dimensions is the dimension of the image

· Spacing is the spacing of the image

· NumberOfScalarComponents should be 1 for grayscale & PALETTE COLOR and 3 for RGB, YBR data.
