vtkVolume16Reader is a source object that reads 16 bit image files.
Volume16Reader 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.
The Transform instance variable specifies a permutation transformation to map slice space into world space. vtkImageReader has replaced the functionality of this class and should be used instead.

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 vtkVolumeReader. |
|
Other objects make use of these methods Implements vtkVolumeReader. |
|
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 vtkVolumeReader. |
|
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 vtkVolumeReader. |
|
Construct object with NULL file prefix; file pattern "s.d"; image range set to (1,1); data origin (0,0,0); data spacing (1,1,1); no data mask; header size 0; and byte swapping turned off. Reimplemented from vtkStructuredPointsSource. |
|
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 vtkVolumeReader. |
|
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 vtkVolumeReader. |
|
These methods should be used instead of the SwapBytes methods. They indicate the byte ordering of the file you are trying to read in. These methods will then either swap or not swap the bytes depending on the byte ordering of the machine it is being run on. For example, reading in a BigEndian file on a BigEndian machine will result in no swapping. Trying to read the same file on a LittleEndian machine will result in swapping. As a quick note most UNIX machines are BigEndian while PC's and VAX tend to be LittleEndian. So if the file you are reading in was generated on a VAX or PC, SetDataByteOrderToLittleEndian otherwise SetDataByteOrderToBigEndian. |
|
Specify the dimensions for the data. |
|
Specify a mask used to eliminate data in the data file (e.g., connectivity bits). |
|
Specify the number of bytes to seek over at start of image. |
|
Turn on/off byte swapping. |
|
Set/Get transformation matrix to transform the data from slice space into world space. This matrix must be a permutation matrix. To qualify, the sums of the rows must be + or - 1. |
