Simple VTK Example
A very simple VTK example - a raw 2D datafile is read
it's magnified by a factor of 3 and then it's displayed on a window.
The pipeline:
vtkImageReader->vtkImageMagnify->vtkRenderWindow
The image file is a raw file of 64 rows * 64 columns. The values are
2 byte (short int) long.
It's a greyscale dataset (NumberOfScalrComponents = 1)
