                  DicomPixelBuffer pixels)

Construct a DICOM slice with a given title, DICOM header information, and image pixels

Method Detail

getPixelType

public DicomPixelBuffer.PixelType getPixelType()

Returns:

Returns the pixel type of the slice (byte/short grayscale, byte RGB)

getPixelBuffer

public DicomPixelBuffer getPixelBuffer()

Returns:

the underlying pixel buffer

getPixels

public void getPixels(int x,
                      int y,
                      int dx,
                      int dy,
