318 This is the main function.
319
320 The program converts one TIFF file to one PDF file, including multiple page
321 TIFF files, tiled TIFF files, black and white. grayscale, and color TIFF
322 files that contain data of TIFF photometric interpretations of bilevel,
323 grayscale, RGB, YCbCr, CMYK separation, and ICC L*a*b* as supported by
324 libtiff and PDF.
325
326 If you have multiple TIFF files to convert into one PDF file then use tiffcp
327 or other program to concatenate the files into a multiple page TIFF file.
328 If the input TIFF file is of huge dimensions (greater than 10000 pixels height
329 or width) convert the input image to a tiled TIFF if it is not already.
330
331 The standard output is standard output. Set the output file name with the
332 "-o output.pdf" option.
333
334 All black and white files are compressed into a single strip CCITT G4 Fax
335 compressed PDF, unless tiled, where tiled black and white images are
336 compressed into tiled CCITT G4 Fax compressed PDF, libtiff CCITT support
337 is assumed.
338
339 Color and grayscale data can be compressed using either JPEG compression,
340 ITU-T T.81, or Zip/Deflate LZ77 compression, per PNG 1.2 and RFC 1951. Set
341 the compression type using the -j or -z options. JPEG compression support
342 requires that libtiff be configured with JPEG support, and Zip/Deflate
343 compression support requires that libtiff is configured with Zip support,
344 in tiffconf.h. Use only one or the other of -j and -z. The -q option
345 sets the image compression quality, that is 1-100 with libjpeg JPEG
346 compression and one of 1, 10, 11, 12, 13, 14, or 15 for PNG group compression
347 predictor methods, add 100, 200, ..., 900 to set zlib compression quality 1-9.
348 PNG Group differencing predictor methods are not currently implemented.
349
350 If the input TIFF contains single strip CCITT G4 Fax compressed information,
351 then that is written to the PDF file without transcoding, unless the options
352 of no compression and no passthrough are set, -d and -n.
353
354 If the input TIFF contains JPEG or single strip Zip/Deflate compressed
355 information, and they are configured, then that is written to the PDF file
356 without transcoding, unless the options of no compression and no passthrough
357 are set.
358
359 The default page size upon which the TIFF image is placed is determined by
360 the resolution and extent of the image data. Default values for the TIFF
361 image resolution can be set using the -x and -y options. The page size can
362 be set using the -p option for paper size, or -w and -l for paper width and
363 length, then each page of the TIFF image is centered on its page. The
364 distance unit for default resolution and page width and length can be set
365 by the -u option, the default unit is inch.
366
367 Various items of the output document information can be set with the -e, -c,
368 -a, -t, -s, and -k tags. Setting the argument of the option to "" for these
369 tags causes the relevant document information field to be not written. Some
370 of the document information values otherwise get their information from the
371 input TIFF image, the software, author, document name, and image description.
372
373 The output PDF file conforms to the PDF 1.1 specification or PDF 1.2 if using
374 Zip/Deflate compression.

379 Here is a listing of the usage example and the options to the tiff2pdf
380 program that is part of the libtiff distribution. Options followed by
381 a colon have a required argument.
382
383 usage: tiff2pdf [options] input.tif
384
385 options:
386 -o: output to file name
387
388 -j compress with JPEG (requires libjpeg configured with libtiff)
389 -z compress with Zip/Deflate (requires zlib configured with libtiff)
390 -q: compression quality
391 -n no compressed data passthrough
392 -d do not compress (decompress)
393
394 -i invert colors
395
396 -u: set distance unit, 'i' for inch, 'm' for centimeter
397 -x: set x resolution default
398 -y: set y resolution default
399 -w: width in units
400 -l: length in units
401 -r: 'd' for resolution default, 'o' for resolution override
402 -p: paper size, eg "letter", "legal", "A4"
403 -f set PDF "Fit Window" user preference
404 -b set PDF "Interpolate" user preference
405 -e: date, overrides image or current date/time default, YYYYMMDDHHMMSS
406 -c: creator, overrides image software default
407 -a: author, overrides image artist default
408 -t: title, overrides image document name default
409 -s: subject, overrides image image description default
410 -k: keywords
411
412 -h usage
413
414 examples:
415
416 tiff2pdf -o output.pdf input.tiff
417
418 The above example would generate the file output.pdf from input.tiff.
419
420 tiff2pdf input.tiff
421
422 The above example would generate PDF output from input.tiff and write it
423 to standard output.
424
425 tiff2pdf -j -p letter -o output.pdf input.tiff
426
427 The above example would generate the file output.pdf from input.tiff,
428 putting the image pages on a letter sized page, compressing the output
429 with JPEG.

5108
5109 This function writes a PDF to a file given a pointer to a TIFF.
5110
5111 The idea with using a TIFF* as output for a PDF file is that the file
5112 can be created with TIFFClientOpen for memory-mapped use within the TIFF
5113 library, and TIFFWriteEncodedStrip can be used to write compressed data to
5114 the output. The output is not actually a TIFF file, it is a PDF file.
5115
5116 This function uses only TIFFWriteFile and TIFFWriteEncodedStrip to write to
5117 the output TIFF file. When libtiff would otherwise be writing data to the
5118 output file, the write procedure of the TIFF structure is replaced with an
5119 empty implementation.
5120
5121 The first argument to the function is an initialized and validated T2P
5122 context struct pointer.
5123
5124 The second argument to the function is the TIFF* that is the input that has
5125 been opened for reading and no other functions have been called upon it.
5126
5127 The third argument to the function is the TIFF* that is the output that has
5128 been opened for writing. It has to be opened so that it hasn't written any
5129 data to the output. If the output is seekable then it's OK to seek to the
5130 beginning of the file. The function only writes to the output PDF and does
5131 not seek. See the example usage in the main() function.
5132
5133 TIFF* output = TIFFOpen("output.pdf", "w");
5134 assert(output != NULL);

5140 This function returns the file size of the output PDF file. On error it
5141 returns zero and the t2p->t2p_error variable is set to T2P_ERR_ERROR.
5142
5143 After this function completes, call t2p_free on t2p, TIFFClose on input,
