This class represents the ccittfax parameters. This is definitively detailed in:.

The CCITT decode parameters dictionary configures the CCITTFaxDecode filter, which implements the CCITT facsimile compression algorithms used for bi-level (black and white) image data.

The K entry selects the encoding scheme: a negative value uses Group 4 (two-dimensional), zero uses Group 3 one-dimensional, and a positive value uses mixed Group 3 encoding where the value limits the number of consecutive two-dimensional rows.

Group 4 encoding is generally more compact than Group 3 and is the most common choice for scanned document images. Group 3 encoding with K of 0 is compatible with older fax equipment.

The Columns and Rows entries define the image dimensions. The EndOfBlock entry controls whether an end-of-facsimile-block code terminates the data. The BlackIs1 entry controls the polarity of the image.

The DamagedRowsBeforeError entry allows a decoder to tolerate a limited number of corrupted scan lines before treating the stream as an error. This supports recovery from transmission errors in legacy fax data.
