Field Summary

Fields

Modifier and Type	Field	Description
static final int	CCITT_BLACKIS1	A flag indicating whether 1-bits are to be interpreted as black pixels and 0-bits as white pixels,
static final int	CCITT_ENCODEDBYTEALIGN	A flag indicating whether the filter expects extra 0-bits before each encoded line so that the line begins on a byte boundary.
static final int	CCITT_ENDOFBLOCK	A flag indicating whether the filter expects the encoded data to be terminated by an end-of-block pattern, overriding the Rows parameter.
static final int	CCITT_ENDOFLINE	A flag indicating whether end-of-line bit patterns are required to be present in the encoding.
static final int	CCITTG3_1D	Pure one-dimensional encoding (Group 3, 1-D)
static final int	CCITTG3_2D	Mixed one- and two-dimensional encoding (Group 3, 2-D)
static final int	CCITTG4	Pure two-dimensional encoding (Group 4)
protected int	typeCcitt	CCITT compression type when the image uses CCITT encoding.
