Detailed Description

read 16 bit image files

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.

void vtkVolume16Reader::SetDataByteOrderToBigEndian ( )

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.
