// .NAME vtkVolumeReader - read image files
|
|
// .SECTION Description
|
|
// 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:
|
|
// sprintf (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 imbedded
|
|
// 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.
