/**
* @class vtkPNMReader
* @brief read pnm (i.e., portable anymap) files
*
*
* vtkPNMReader is a source object that reads pnm (portable anymap) files.
* This includes .pbm (bitmap), .pgm (grayscale), and .ppm (pixmap) files.
* (Currently this object only reads binary versions of these files.)
*
* PNMReader 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.
*
* To read a volume, files must be of the form "FileName.<number>" (e.g.,
* foo.ppm.0, foo.ppm.1, ...). You must also specify the DataExtent. The
* fifth and sixth values of the DataExtent specify the beginning and ending
* files to read.
