/*

|
|
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.

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
|
|
|
|

|
|
|
|
|
|
|

|
2003-11-25 11:39:22 -05:00
|
|
|
-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
|
|
|

|
|
|
|
|
|
|
|
-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 TIFFWriteFile 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){
|
|
|
|
TIFFSeekFile(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.
