Pixels are this type in the file. This is an alternative way of setting the dimensions. It is more compatable with the imaging pipelines. Set the image dimensions. This also computes the increments.
Dimensions have to be set manually because, the header is ignored.
This is here for compatability with the vtkVolume16 reader. If there is a tail on the file, you want to explicitly set the header size. The mask is for legacy compatablilty. These methods should be used instead of the SwapBytes methods. They indicate the byte ordering of the file you are trying to read in.
