/*
This is the main function.
The program converts one TIFF file to one PDF file, including multiple page
TIFF files, tiled TIFF files, black and white. grayscale, and color TIFF
files that contain data of TIFF photometric interpretations of bilevel,
grayscale, RGB, YCbCr, CMYK separation, and ICC L*a*b* as supported by
libtiff and PDF.
If you have multiple TIFF files to convert into one PDF file then use tiffcp
or other program to concatenate the files into a multiple page TIFF file.
If the input TIFF file is of huge dimensions (greater than 10000 pixels height
or width) convert the input image to a tiled TIFF if it is not already.
The standard output is standard output. Set the output file name with the
"-o output.pdf" option.
All black and white files are compressed into a single strip CCITT G4 Fax
compressed PDF, unless tiled, where tiled black and white images are
compressed into tiled CCITT G4 Fax compressed PDF, libtiff CCITT support
is assumed.
Color and grayscale data can be compressed using either JPEG compression,
ITU-T T.81, or Zip/Deflate LZ77 compression, per PNG 1.2 and RFC 1951. Set
the compression type using the -j or -z options. JPEG compression support
requires that libtiff be configured with JPEG support, and Zip/Deflate
compression support requires that libtiff is configured with Zip support,
in tiffconf.h. Use only one or the other of -j and -z. The -q option
sets the image compression quality, that is 1-100 with libjpeg JPEG
compression and one of 1, 10, 11, 12, 13, 14, or 15 for PNG group compression
predictor methods, add 100, 200, ..., 900 to set zlib compression quality 1-9.
PNG Group differencing predictor methods are not currently implemented.
If the input TIFF contains single strip CCITT G4 Fax compressed information,
then that is written to the PDF file without transcoding, unless the options
of no compression and no passthrough are set, -d and -n.
If the input TIFF contains JPEG or single strip Zip/Deflate compressed
information, and they are configured, then that is written to the PDF file
without transcoding, unless the options of no compression and no passthrough
are set.
The default page size upon which the TIFF image is placed is determined by
the resolution and extent of the image data. Default values for the TIFF
image resolution can be set using the -x and -y options. The page size can
be set using the -p option for paper size, or -w and -l for paper width and
length, then each page of the TIFF image is centered on its page. The
distance unit for default resolution and page width and length can be set
by the -u option, the default unit is inch.
Various items of the output document information can be set with the -e, -c,
-a, -t, -s, and -k tags. Setting the argument of the option to "" for these
tags causes the relevant document information field to be not written. Some
of the document information values otherwise get their information from the
input TIFF image, the software, author, document name, and image description.
The output PDF file conforms to the PDF 1.1 specification or PDF 1.2 if using
Zip/Deflate compression.

Systems, Incorporated. Todos derechos reservados.
Here is a listing of the usage example and the options to the tiff2pdf
program that is part of the libtiff distribution. Options followed by
a colon have a required argument.
usage: tiff2pdf [options] input.tif
options:
-o: output to file name
#ifdef JPEG_SUPPORT
-j: compress with JPEG (requires libjpeg configured with libtiff)
#endif
#ifdef ZIP_SUPPORT
printf (-z: compress with Zip/Deflate (requires zlib configured with libtiff));
#endif
-q: compression quality
-n: no compressed data passthrough
-d: do not compress (decompress)
-i: invert colors
-u: set distance unit, 'i' for inch, 'm' for centimeter
-x: set x resolution default
-y: set y resolution default
-w: width in units
-l: length in units
-r: 'd' for resolution default, 'o' for resolution override
-p: paper size, eg "letter", "legal", "a4"
-F: make the tiff fill the PDF page
-f: set pdf "fit window" user preference
-b: set PDF "Interpolate" user preference
-e: date, overrides image or current date/time default, YYYYMMDDHHMMSS
-c: creator, overrides image software default
-a: author, overrides image artist default
-t: title, overrides image document name default
-s: subject, overrides image image description default
-k: keywords
-h: usage
examples:
tiff2pdf -o output.pdf input.tiff
The above example would generate the file output.pdf from input.tiff.
tiff2pdf input.tiff
The above example would generate PDF output from input.tiff and write it
to standard output.
tiff2pdf -j -p letter -o output.pdf input.tiff
The above example would generate the file output.pdf from input.tiff,
putting the image pages on a letter sized page, compressing the output
with JPEG.
