// .NAME vtkPNMReader - read pnm (i.e., portable anymap) files
|
|
|
|
// .SECTION Description
|
|
// 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.
