-+ 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.
-+
-+ The Portable Document Format (PDF) specification is copyrighted by Adobe
-+ 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
-+
-+ -j: compress with JPEG (requires libjpeg configured with libtiff)
-+ -z: compress with Zip/Deflate (requires zlib configured with libtiff)
-+ -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.

-+ This function writes a PDF to a file given a pointer to a TIFF.
-+
-+ The idea with using a TIFF* as output for a PDF file is that the file
-+ can be created with TIFFClientOpen for memory-mapped use within the TIFF
-+ library, and TIFFWriteEncodedStrip can be used to write compressed data to
-+ the output. The output is not actually a TIFF file, it is a PDF file.
-+
-+ This function uses only t2pWriteFile and TIFFWriteEncodedStrip to write to
-+ the output TIFF file. When libtiff would otherwise be writing data to the
-+ output file, the write procedure of the TIFF structure is replaced with an
-+ empty implementation.
-+
-+ The first argument to the function is an initialized and validated T2P
-+ context struct pointer.
-+
-+ The second argument to the function is the TIFF* that is the input that has
-+ been opened for reading and no other functions have been called upon it.
-+
-+ The third argument to the function is the TIFF* that is the output that has
-+ been opened for writing. It has to be opened so that it hasn't written any
-+ data to the output. If the output is seekable then it's OK to seek to the
-+ beginning of the file. The function only writes to the output PDF and does
-+ not seek. See the example usage in the main() function.
