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.

Auto picks the best - * fit for the image on the specified paper size (eg portrait - * or landscape) if -h or -w is specified. Rotation is in - * degrees counterclockwise since that is how Postscript does - * it. Auto rotates 90 degrees ccw to produce landscape. - * - * Added maxPageWidth option using -W flag. MaxPageHeight and - * MaxPageWidth are mutually exclusive since the aspect ratio - * cannot be maintained if you set both. - * Rewrote PlaceImage to allow maxPageHeight and maxPageWidth - * options to work with values smaller or larger than the - * physical paper size and still preserve the aspect ratio. - * This is accomplished by creating multiple pages across - * as well as down if need be. - * - * 2001-Mar-21 - * I (Bruce A. Mallett) added this revision history comment ;) - * - * Fixed PS_Lvl2page() code which outputs non-ASCII85 raw - * data. Moved test for when to output a line break to - * *after* the output of a character. This just serves - * to fix an eye-nuisance where the first line of raw - * data was one character shorter than subsequent lines. - * - * Added an experimental ASCII85 encoder which can be used - * only when there is a single buffer of bytes to be encoded. - * This version is much faster at encoding a straight-line - * buffer of data because it can avoid alot of the loop - * overhead of the byte-by-bye version. To use this version - * you need to define EXP_ASCII85ENCODER (experimental ...). - * - * Added bug fix given by Michael Schmidt to PS_Lvl2page() - * in which an end-of-data marker ('>') was not being output - * when producing non-ASCII85 encoded PostScript Level 2 - * data. - * - * Fixed PS_Lvl2colorspace() so that it no longer assumes that - * a TIFF having more than 2 planes is a CMYK. This routine - * no longer looks at the samples per pixel but instead looks - * at the "photometric" value. This change allows support of - * CMYK TIFFs. - * - * Modified the PostScript L2 imaging loop so as to test if - * the input stream is still open before attempting to do a - * flushfile on it. This was done because some RIPs close - * the stream after doing the image operation. - * - * Got rid of the realloc() being done inside a loop in the - * PSRawDataBW() routine. The code now walks through the - * byte-size array outside the loop to determine the largest - * size memory block that will be needed. - * - * Added "-m" switch to ask tiff2ps to, where possible, use the - * "imagemask" operator instead of the "image" operator. - * - * Added the "-i #" switch to allow interpolation to be disabled. - * - * Unrolled a loop or two to improve performance. - */ - -/* - * Define EXP_ASCII85ENCODER if you want to use an experimental - * version of the ASCII85 encoding routine. The advantage of - * using this routine is that tiff2ps will convert to ASCII85 - * encoding at between 3 and 4 times the speed as compared to - * using the old (non-experimental) encoder. The disadvantage - * is that you will be using a new (and unproven) encoding - * routine.
