| 467 | |
| 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. |

| 5212 | returns zero and the t2p->t2p_error variable is set to T2P_ERR_ERROR. |
| 5213 | |
