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 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. 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, in
tiffconf.h. 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.
