Detailed Description

map a slice of a vtkImageData to the screen

vtkImageSliceMapper is a mapper that will draw a 2D image, or a slice of a 3D image. For 3D images, the slice may be oriented in the X, Y, or Z direction. This mapper works via 2D textures with accelerated zoom and pan operations.

Thanks:
Thanks to David Gobbi at the Seaman Family MR Centre and Dept. of Clinical Neurosciences, Foothills Medical Centre, Calgary, for providing this class.
