-
- 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.
-
- TIFF* output = TIFFOpen("output.pdf", "w");
- assert(output != NULL);
-
- if(output->tif_seekproc != NULL){
- t2pSeekFile(output, (toff_t) 0, SEEK_SET);
- }
-
- This function returns the file size of the output PDF file. On error it
- returns zero and the t2p->t2p_error variable is set to T2P_ERR_ERROR.
-
- After this function completes, call t2p_free on t2p, TIFFClose on input,
- and TIFFClose on output.
