The ByteBuffer
is a class of byte array for an image
buffer.
The return value of get and the value for set
is between 0 and 255. If 257 is passed to set, it is
converted to 1. If -1 is passed, it is converted to 255.
The value in the buffer 0 represents 0, 127 does 127, -128 does 128, and -1 does 255.
