sfftobmp - SFF (Structured Fax File) Converter
SYNOPSIS
sfftobmp [options] INFILE1 [INFILE2 ..] [-o OUTSPEC]
OPTIONS -h or -help Show this message and exit
-v or -version Show version and exit
-b or -bmp Output is one monochrome BMP file for each fax page
-p or -pbm Output is one Portable Bitmap file for each fax page
-j or -jpg Output is one JPEG file for each fax page
-jNUM or -jpg=NUM Use jpeg quality of NUM percent (1..99)
-T or -tifs Output is one single-page TIFF file for each fax page
-t or -tif Output is one multi-paged TIFF file containing all pages
-r or -keepres Inhibit line doubling for low-res faxes
-d or -keepdate Keep date and time of input file for the output file(s)
The OUTSPEC is interpreted as:
- a filename if only one input file is given. - a directory name if more than one input file is given.
If OUTSPEC is omitted, the name of the output files will be derived from the input files and created in the same directory.
Output on stdout is available for multipaged TIFF output only (option "-t"). Use "-" as output filename in this case.
In case of TIFF output, you can specify the compression by using additional specifiers:
-tr resp. -Tr : CCITT modified Huffman RLE
-t4 resp. -T4 : CCITT Fax Class 4 compression
The default is CCITT Fax Class 3 compression.

fax2tiff - create a TIFF Class F fax file from raw fax data
SYNOPSIS
fax2tiff [options] [-o output.tif] input.g3
DESCRIPTION
fax2tiff creates a TIFF file containing CCITT Group 3 or Group 4 encoded data from one or more files containing "raw" Group 3 encoded data,
typically obtained directly from a fax modem.
By default, each row of data in the resultant TIFF file is 2-dimensionally encoded and padded or truncated to 1728 pixels, as needed. The
resultant image is a set of low resolution (98 lines per inch) or medium resolution (196 lines per inch) pages, each of which is a single
strip of data.
OPTIONS
Input Data Options
The following input data options are supported:
-2 Assume input data is 2-d Huffman encoded.
-B Assume input data was encoded with black as 0 and white as 1.
-L Treat input data as having bits filled from least significant bit (LSB) to most significant bit (MSB). This is the default.
-M Treat input data as having bits filled from most significant bit (MSB) to least significant bit (LSB).
-R Specify the vertical resolution, in lines per inch, of the input images. By default, input images are assumed to have a
vertical resolution of 196 lines per inch. If images are low resolution facsimile, specify a value of 98 lines per inch.
-W Assume input data was encoded with black as 1 and white as 0. This is the default.
Output File Options
The following output file options are supported:
-1 Force output to be compressed with the 1-dimensional version of the CCITT Group 3 Huffman encoding algorithm.
-4 Force output to be compressed with the CCITT Group 4 Huffman encoding.
-o Specify the name of the output file.
-p Force the last bit of each End Of Line (EOL) code to land on a byte boundary. This "zero padding" is reflected in the con-
tents of the Group3Options tag of the resultant TIFF file.
-s Stretch the input image vertically by writing each input row of data twice to the output file.
-v Force fax2tiff to print the number of rows of data retrieved from the input file.
OPERANDS
The following operands are supported:
input.g3 The name of the input file that contains raw fax data.
EXTENDED DESCRIPTION
The generated file conforms to the TIFF Class F (FAX) specification for storing facsimile data. This means, in particular, that each page
of the data does not include the trailing return to control (RTC) code, as required for transmission by the CCITT Group 3 specifications.
The old, "classic" format is created if the -c option is used. The Class F format can also be requested with the -f option.
The default name of the output image is fax.tif. You can use the -o option to change the output filename.
Each input file is assumed to be a separate page of facsimile data from the same document. The order in which input files are specified on
the command line is the order in which the resultant pages appear in the output file.
Diagnostics
The following warnings and errors come from the decoding routines in the library.
Warning, %s: Premature ETheainputndata had(a row.that was shorter than the expected value of 1728. The row is padded with white.
%s: Premature EOF at scaThendecoder ran.out of data in the middle of a scanline. The resultant row is padded with white.
%s: Bad code word at rowAnd,invalid Group 3 code was encountered while decoding the input file. The row number and horizontal position is
given. The remainder of the input row is discarded, while the corresponding output row is padded with white.
%s: Bad 2D code word at AnainvaliddGroup 4 or 2D Group 3 code was encountered while decoding the input file. The row number and horizontal
position is given. The remainder of the input row is discarded, while the corresponding output row is padded with
white.
