Class PdfSubByteSampleModel

    java.lang.Object
      java.awt.image.SampleModel
          com.sun.pdfview.PdfSubByteSampleModel

    public class PdfSubByteSampleModel

extends java.awt.image.SampleModel

Provides a read-only sample-model where components are less than a byte in width while allowing for pixels to cross byte-boundaries. For example, this allows 2 pixels made of 3 4-bit-bands (p[pixel,band]) to be stored in 3 bytes as p[0,1] p[0,2] | p[0,3] p[1,0] | p[1,1] p[1,2]. `MultiPixelPackedSampleModel`, which allows for sub-byte components, does not allow for such byte spanning, while the PDF specification does permit it -- hence the existence of this class.
