Examples of PackedImageData

com.lightcrafts.mediax.jai.PackedImageData
This class is used by PixelAccessor to store packed image data along with access information. The data must be single banded and one bit in depth, and are stored in a one-dimensional byte array, with eight pixels packed into one byte. To insure that each scanline has an integral number of bytes the last byte may be padded with zeros. @since JAI 1.1
