Constructor

Parameters:

imageBuffer - that need to be decoded

ccittGroup - a code identifying the encoding scheme used

isEndofLine - A flag indicating whether end-of-line bit patterns are required to be present in the encoding.

isEncodedByteAlign - A flag indicating whether the filter expects extra 0 bits before each encoded line so that the line begins on a byte boundary.

columns - The width of the image in pixels.

rows - The height of the image in scan lines.

isBlack1 - a flag indicating whether 1 bits are to be interpreted as black pixels and 0 bits as white pixels.
