+
+  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

+
+  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");

+	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.
