/**
* @class vtkVolumeReader
* @brief read image files
*
* vtkVolumeReader is a source object that reads image files.
*
* VolumeReader creates structured point datasets. The dimension of the
* dataset depends upon the number of files read. Reading a single file
* results in a 2D image, while reading more than one file results in a
* 3D volume.
*
* File names are created using FilePattern and FilePrefix as follows:
* snprintf (filename, sizeof(filename), FilePattern, FilePrefix, number);
* where number is in the range ImageRange[0] to ImageRange[1]. If
* ImageRange[1] <= ImageRange[0], then slice number ImageRange[0] is
* read. Thus to read an image set ImageRange[0] = ImageRange[1] = slice
* number. The default behavior is to read a single file (i.e., image slice 1).
*
* The DataMask instance variable is used to read data files with embedded
* connectivity or segmentation information. For example, some data has
* the high order bit set to indicate connected surface. The DataMask allows
* you to select this data. Other important ivars include HeaderSize, which
* allows you to skip over initial info, and SwapBytes, which turns on/off
* byte swapping. Consider using vtkImageReader as a replacement.
