Create a TIFF Class F fax file from raw fax data

usage: fax2tiff [options] input.raw...
where options are:
 -3		input data is G3-encoded		[default]
 -4		input data is G4-encoded
 -U		input data is uncompressed (G3 or G4)
 -1		input data is 1D-encoded (G3 only)	[default]
 -2		input data is 2D-encoded (G3 only)
 -P		input is not EOL-aligned (G3 only)	[default]
 -A		input is EOL-aligned (G3 only)
 -M		input data has MSB2LSB bit order
 -L		input data has LSB2MSB bit order	[default]
 -B		input data has min 0 means black
 -b		input data has min 0 means black (same as -B)
 -W		input data has min 0 means white	[default]
 -w		input data has min 0 means white (same as -W)
 -R #		input data has # resolution (lines/inch) [default is 196]
 -X #		input data has # width			[default is 1728]

 -o out.tif	write output to out.tif
 -7		generate G3-encoded output		[default]
 -8		generate G4-encoded output
 -u		generate uncompressed output (G3 or G4)
 -5		generate 1D-encoded output (G3 only)
 -6		generate 2D-encoded output (G3 only)	[default]
 -p		generate not EOL-aligned output (G3 only)
 -a		generate EOL-aligned output (G3 only)	[default]
 -c		generate "classic" TIFF format
 -f		generate TIFF Class F (TIFF/F) format	[default]
 -m		output fill order is MSB2LSB
 -l		output fill order is LSB2MSB		[default]
 -r #		make each strip have no more than # rows
 -s		stretch image by duplicating scanlines
 -v		print information about conversion work
 -z		generate LZW compressed output
