NAME

       tiff2pdf - convert a TIFF image to a PDF document

SYNOPSIS

       tiff2pdf [ options ] input.tiff

DESCRIPTION

       tiff2pdf opens a TIFF image and writes a PDF document to standard output.

       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 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.  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 be configured with Zip support.  Use only one or
       the other of -j and -z.

       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  options.   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.

OPTIONS

       -o output-file
              Set the output to go to file output-file

       -j     Compress with JPEG (requires libjpeg configured with libtiff).

       -z     Compress with Zip/Deflate (requires :program`zlib` configured with libtiff).

       -p paper-size
              Set paper size, e.g., letter,  legal, A4.

       -F     Cause the tiff to fill the PDF page.

       -u [ i | m ]
              Set distance unit, i for inch, m for centimeter.

       -w width
              Set width in units.

       -l length
              Set length in units.

       -x xres
              Set x/width resolution default.

       -y yres
              Set y/length resolution default.

       -r [ d | o ]
              Set d for resolution default  for  images  without  resolution,  o  for  resolution
              override for all images.

       -f     Set PDF Fit Window user preference.

       -e YYYYMMDDHHMMSS
              Set  document  information  date,  overrides  image  or  current date/time default,
              YYYYMMDDHHMMSS.

              Set document information creator, overrides image software default.

       -a author
              Set document information author, overrides image artist default.

       -h     List usage reminder to stderr and exit.

EXAMPLES

       The following example would generate the file output.pdf from input.tiff:

          tiff2pdf -o output.pdf input.tiff

       The  following  example would generate PDF output from input.tiff and write it to standard
       output:

          tiff2pdf input.tiff

       The following example would generate the file  output.pdf  from  input.tiff,  putting  the
       image  pages  on  a letter sized page, compressing the output with JPEG, with JPEG quality
       75, setting the title to Document, and setting the Fit Window option:

          tiff2pdf -p letter -j -q 75 -t "Document" -f -o output.pdf input.tiff
