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.

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkStructuredPointsSource. Reimplemented in vtkVolume16Reader. |
|
Other objects make use of this method. Implemented in vtkVolume16Reader. |
|
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkStructuredPointsSource. Reimplemented in vtkVolume16Reader. |
|
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkStructuredPointsSource. Reimplemented in vtkVolume16Reader. |
|
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkSource. Reimplemented in vtkVolume16Reader. |
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkStructuredPointsSource. Reimplemented in vtkVolume16Reader. |
