468 This is the main function.
469
470 The program converts one TIFF file to one PDF file, including multiple page
471 TIFF files, tiled TIFF files, black and white. grayscale, and color TIFF
472 files that contain data of TIFF photometric interpretations of bilevel,
473 grayscale, RGB, YCbCr, CMYK separation, and ICC L*a*b* as supported by
474 libtiff and PDF.
475
476 If you have multiple TIFF files to convert into one PDF file then use tiffcp
477 or other program to concatenate the files into a multiple page TIFF file.
478 If the input TIFF file is of huge dimensions (greater than 10000 pixels height
479 or width) convert the input image to a tiled TIFF if it is not already.
480
481 The standard output is standard output. Set the output file name with the
482 "-o output.pdf" option.
483
484 All black and white files are compressed into a single strip CCITT G4 Fax
485 compressed PDF, unless tiled, where tiled black and white images are
486 compressed into tiled CCITT G4 Fax compressed PDF, libtiff CCITT support
487 is assumed.
488
489 Color and grayscale data can be compressed using either JPEG compression,
490 ITU-T T.81, or Zip/Deflate LZ77 compression, per PNG 1.2 and RFC 1951. Set
491 the compression type using the -j or -z options. JPEG compression support
492 requires that libtiff be configured with JPEG support, and Zip/Deflate
493 compression support requires that libtiff is configured with Zip support,
494 in tiffconf.h. Use only one or the other of -j and -z. The -q option
495 sets the image compression quality, that is 1-100 with libjpeg JPEG
496 compression and one of 1, 10, 11, 12, 13, 14, or 15 for PNG group compression
497 predictor methods, add 100, 200, ..., 900 to set zlib compression quality 1-9.
498 PNG Group differencing predictor methods are not currently implemented.
499
500 If the input TIFF contains single strip CCITT G4 Fax compressed information,
501 then that is written to the PDF file without transcoding, unless the options
502 of no compression and no passthrough are set, -d and -n.
503
504 If the input TIFF contains JPEG or single strip Zip/Deflate compressed
505 information, and they are configured, then that is written to the PDF file
506 without transcoding, unless the options of no compression and no passthrough
507 are set.
508
509 The default page size upon which the TIFF image is placed is determined by
510 the resolution and extent of the image data. Default values for the TIFF
511 image resolution can be set using the -x and -y options. The page size can
512 be set using the -p option for paper size, or -w and -l for paper width and
513 length, then each page of the TIFF image is centered on its page. The
514 distance unit for default resolution and page width and length can be set
515 by the -u option, the default unit is inch.
516
517 Various items of the output document information can be set with the -e, -c,
518 -a, -t, -s, and -k tags. Setting the argument of the option to "" for these
519 tags causes the relevant document information field to be not written. Some
520 of the document information values otherwise get their information from the
521 input TIFF image, the software, author, document name, and image description.
522
523 The output PDF file conforms to the PDF 1.1 specification or PDF 1.2 if using
524 Zip/Deflate compression.

529 Here is a listing of the usage example and the options to the tiff2pdf
530 program that is part of the libtiff distribution. Options followed by
531 a colon have a required argument.
532
533 usage: tiff2pdf [options] input.tif
534
535 options:
536 -o: output to file name
537
538 -j: compress with JPEG (requires libjpeg configured with libtiff)
539 -z: compress with Zip/Deflate (requires zlib configured with libtiff)
540 -q: compression quality
541 -n: no compressed data passthrough
542 -d: do not compress (decompress)
543 -i: invert colors
544 -u: set distance unit, 'i' for inch, 'm' for centimeter
545 -x: set x resolution default
546 -y: set y resolution default
547 -w: width in units
548 -l: length in units
549 -r: 'd' for resolution default, 'o' for resolution override
550 -p: paper size, eg "letter", "legal", "a4"
551 -F: make the tiff fill the PDF page
552 -f: set pdf "fit window" user preference
553 -b: set PDF "Interpolate" user preference
554 -e: date, overrides image or current date/time default, YYYYMMDDHHMMSS
555 -c: creator, overrides image software default
556 -a: author, overrides image artist default
557 -t: title, overrides image document name default
558 -s: subject, overrides image image description default
559 -k: keywords
560
561 -h: usage
562
563 examples:
564
565 tiff2pdf -o output.pdf input.tiff
566
567 The above example would generate the file output.pdf from input.tiff.
568
569 tiff2pdf input.tiff
570
571 The above example would generate PDF output from input.tiff and write it
572 to standard output.
573
574 tiff2pdf -j -p letter -o output.pdf input.tiff
575
576 The above example would generate the file output.pdf from input.tiff,
577 putting the image pages on a letter sized page, compressing the output
578 with JPEG.

5180 This function writes a PDF to a file given a pointer to a TIFF.
5181
5182 The idea with using a TIFF* as output for a PDF file is that the file
5183 can be created with TIFFClientOpen for memory-mapped use within the TIFF
5184 library, and TIFFWriteEncodedStrip can be used to write compressed data to
5185 the output. The output is not actually a TIFF file, it is a PDF file.
5186
5187 This function uses only t2pWriteFile and TIFFWriteEncodedStrip to write to
5188 the output TIFF file. When libtiff would otherwise be writing data to the
5189 output file, the write procedure of the TIFF structure is replaced with an
5190 empty implementation.
5191
5192 The first argument to the function is an initialized and validated T2P
5193 context struct pointer.
5194
5195 The second argument to the function is the TIFF* that is the input that has
5196 been opened for reading and no other functions have been called upon it.
5197
5198 The third argument to the function is the TIFF* that is the output that has
5199 been opened for writing. It has to be opened so that it hasn't written any
5200 data to the output. If the output is seekable then it's OK to seek to the
5201 beginning of the file. The function only writes to the output PDF and does
5202 not seek. See the example usage in the main() function.
