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.

As each byte is placed into ascii85_p this -* external is decremented. If the variable is decrement to -* or past zero then a newline is inserted into ascii85_p -* and the A85BREAKCNTR is then reset to A85BREAKLEN. -* Note: for efficiency reasons the A85BREAKCNTR variable -* is not actually checked on *every* character -* placed into ascii85_p but often only for every -* 5 characters. -* -* THE CALLER IS RESPONSIBLE FOR ENSURING THAT ASCII85_P[] IS -* SUFFICIENTLY LARGE TO THE ENCODED DATA! -* You will need at least 5 * (raw_l/4) bytes plus space for -* newline characters and space for an EOD marker (if -* requested). A safe calculation is to use 6*(raw_l/4) + 8 -* to size ascii85_p. -* -*****************************************************************************/ - -int Ascii85EncodeBlock( uint8 * ascii85_p, unsigned f_eod, const uint8 * raw_p, int raw_l ) - -{ - char ascii85[5]; /* Encoded 5 tuple */ - int ascii85_l; /* Number of bytes written to ascii85_p[] */ - int rc; /* Return code */ - uint32 val32; /* Unencoded 4 tuple */ - - ascii85_l = 0; /* Nothing written yet */ - - if ( raw_p ) - { - --raw_p; /* Prepare for pre-increment fetches */ - - for ( ; raw_l > 3; raw_l -= 4 ) - { - val32 = *(++raw_p) << 24; - val32 += *(++raw_p) << 16; - val32 += *(++raw_p) << 8; - val32 += *(++raw_p); - - if ( val32 == 0 ) /* Special case */ - { - ascii85_p[ascii85_l] = 'z'; - rc = 1; - } - - else - { - ascii85[4] = (char) ((val32 % 85) + 33); - val32 /= 85; - - ascii85[3] = (char) ((val32 % 85) + 33); - val32 /= 85; - - ascii85[2] = (char) ((val32 % 85) + 33); - val32 /= 85; - - ascii85[1] = (char) ((val32 % 85) + 33); - ascii85[0] = (char) ((val32 / 85) + 33); - - _TIFFmemcpy( &ascii85_p[ascii85_l], ascii85, sizeof(ascii85) ); - rc = sizeof(ascii85); - } - - ascii85_l += rc; - - if ( (A85BREAKCNTR -= rc) <= 0 ) - { - ascii85_p[ascii85_l] = '\n'; - ++ascii85_l; - A85BREAKCNTR = A85BREAKLEN; - } - } - - /* - * Output any straggler bytes: - */ - - if ( raw_l > 0 ) - { - int len; /* Output this many bytes */ - - len = raw_l + 1; - val32 = *++raw_p << 24; /* Prime the pump */ - - if ( --raw_l > 0 ) val32 += *(++raw_p) << 16; - if ( --raw_l > 0 ) val32 += *(++raw_p) << 8; - - val32 /= 85; - - ascii85[3] = (char) ((val32 % 85) + 33); - val32 /= 85; - - ascii85[2] = (char) ((val32 % 85) + 33); - val32 /= 85; - - ascii85[1] = (char) ((val32 % 85) + 33); - ascii85[0] = (char) ((val32 / 85) + 33); - - _TIFFmemcpy( &ascii85_p[ascii85_l], ascii85, len ); - ascii85_l += len; - } - } - - /* - * If requested add an ASCII85 End Of Data marker: - */ - - if ( f_eod ) - { - ascii85_p[ascii85_l++] = '~'; - ascii85_p[ascii85_l++] = '>'; - ascii85_p[ascii85_l++] = '\n'; - } - - return ( ascii85_l ); - -} /* Ascii85EncodeBlock() */ - -#endif /* EXP_ASCII85ENCODER */ - - -char* stuff[] = { -"usage: tiff2ps [options] input.tif ...", -"where options are:", -" -1 generate PostScript Level 1 (default)", -" -2 generate PostScript Level 2", -" -3 generate PostScript Level 3", -" -8 disable use of ASCII85 encoding with PostScript Level 2/3", -" -a convert all directories in file (default is first)", -" -b # set the bottom margin to # inches", -" -c center image (-b and -l still add to this)", -" -d # convert directory number #", -" -D enable duplex printing (two pages per sheet of paper)", -" -e generate Encapsulated PostScript (EPS) (implies -z)", -" -h # assume printed page height is # inches (default 11)", -" -w # assume printed page width is # inches (default 8.5)", -" -H # split image if height is more than # inches", -" -W # split image if width is more than # inches", -" -L # overLap split images by # inches", -" -i # enable/disable (Nz/0) pixel interpolation (default: enable)", -" -l # set the left margin to # inches", -" -m use \"imagemask\" operator instead of \"image\"", -" -o # convert directory at file offset #", -" -O file write PostScript to file instead of standard output", -" -p generate regular PostScript", -" -r # or auto rotate by 90, 180, 270 degrees or auto", -" -s generate PostScript for a single image", -" -T print pages for top edge binding", -" -x override resolution units as centimeters", -" -y override resolution units as inches", -" -z enable printing in the deadzone (only for PostScript Level 2/3)", -NULL -}; - -static void -usage(int code) -{ - char buf[BUFSIZ]; - int i; - - setbuf(stderr, buf); - fprintf(stderr, "%s\n\n", TIFFGetVersion()); - for (i = 0; stuff[i] != NULL; i++) - fprintf(stderr, "%s\n", stuff[i]); - exit(code); -} - -/* vim: set ts=8 sts=8 sw=8 noet: */ -/* - * Local Variables: - * mode: c - * c-basic-offset: 8 - * fill-column: 78 - * End: - */ -- cgit v1.2.3
