Replaced original PlaceImage function with several 52 * new functions that make support for multiple output pages 53 * from a single image easier to understand. Added additional 54 * warning messages for incompatible command line options. 55 * Add new command line options to specify PageOrientation 56 * Document Structuring Comment for landscape or portrait 57 * and code to determine the values from ouput width and height 58 * if not specified on the command line. 59 * Add new command line option to specify document creator 60 * as an alterntive to the string "tiff2ps" following model 61 * of patch submitted by Thomas Jarosch for specifiying a 62 * document title which is also supported now. 63 * 64 * 2009-Feb-11 65 * Richard Nolde: Added support for rotations of 90, 180, 270 66 * and auto using -r <90|180|270|auto>. Auto picks the best 67 * fit for the image on the specified paper size (eg portrait 68 * or landscape) if -h or -w is specified. Rotation is in 69 * degrees counterclockwise since that is how Postscript does 70 * it. The auto opption rotates the image 90 degrees ccw to 71 * produce landscape if that is a better fit than portait. 72 * 73 * Cleaned up code in TIFF2PS and broke into smaller functions 74 * to simplify rotations. 75 * 76 * Identified incompatible options and returned errors, eg 77 * -i for imagemask operator is only available for Level2 or 78 * Level3 Postscript in the current implmentation since there 79 * is a difference in the way the operands are called for Level1 80 * and there is no function to provide the Level1 version. 81 * -H was not handled properly if -h and/or -w were specified. 82 * It should only clip the masked images if the scaled image 83 * exceeds the maxPageHeight specified with -H. 84 * 85 * New design allows for all of the following combinations: 86 * Conversion of TIFF to Postscript with optional rotations 87 * of 90, 180, 270, or auto degrees counterclockwise 88 * Conversion of TIFF to Postscript with entire image scaled 89 * to maximum of values spedified with -h or -w while 90 * maintaining aspect ratio. Same rotations apply. 91 * Conversion of TIFF to Postscript with clipping of output 92 * viewport to height specified with -H, producing multiple 93 * pages at this height and original width as needed. 94 * Same rotations apply. 95 * Conversion of TIFF to Postscript with image scaled to 96 * maximum specified by -h and -w and the resulting scaled 97 * image is presented in an output viewport clipped by -H height. 98 * The same rotations apply. 99 * 100 * Added maxPageWidth option using -W flag. MaxPageHeight and 101 * MaxPageWidth are mutually exclusive since the aspect ratio 102 * cannot be maintained if you set both. 103 * Rewrote PlaceImage to allow maxPageHeight and maxPageWidth 104 * options to work with values smaller or larger than the 105 * physical paper size and still preserve the aspect ratio. 106 * This is accomplished by creating multiple pages across 107 * as well as down if need be. 108 * 109 * 2001-Mar-21 110 * I (Bruce A. Mallett) added this revision history comment ;) 111 * 112 * Fixed PS_Lvl2page() code which outputs non-ASCII85 raw 113 * data. Moved test for when to output a line break to 114 * *after* the output of a character. This just serves 115 * to fix an eye-nuisance where the first line of raw 116 * data was one character shorter than subsequent lines. 117 * 118 * Added an experimental ASCII85 encoder which can be used 119 * only when there is a single buffer of bytes to be encoded. 120 * This version is much faster at encoding a straight-line 121 * buffer of data because it can avoid a lot of the loop 122 * overhead of the byte-by-byte version. To use this version 123 * you need to define EXP_ASCII85ENCODER (experimental ...). 124 * 125 * Added bug fix given by Michael Schmidt to PS_Lvl2page() 126 * in which an end-of-data marker ('>') was not being output 127 * when producing non-ASCII85 encoded PostScript Level 2 128 * data. 129 * 130 * Fixed PS_Lvl2colorspace() so that it no longer assumes that 131 * a TIFF having more than 2 planes is a CMYK. This routine 132 * no longer looks at the samples per pixel but instead looks 133 * at the "photometric" value. This change allows support of 134 * CMYK TIFFs. 135 * 136 * Modified the PostScript L2 imaging loop so as to test if 137 * the input stream is still open before attempting to do a 138 * flushfile on it. This was done because some RIPs close 139 * the stream after doing the image operation. 140 * 141 * Got rid of the realloc() being done inside a loop in the 142 * PSRawDataBW() routine. The code now walks through the 143 * byte-size array outside the loop to determine the largest 144 * size memory block that will be needed. 145 * 146 * Added "-m" switch to ask tiff2ps to, where possible, use the 147 * "imagemask" operator instead of the "image" operator. 148 * 149 * Added the "-i #" switch to allow interpolation to be disabled. 150 * 151 * Unrolled a loop or two to improve performance. 152 */ 153 154 /* 155 * Define EXP_ASCII85ENCODER if you want to use an experimental 156 * version of the ASCII85 encoding routine. The advantage of 157 * using this routine is that tiff2ps will convert to ASCII85 158 * encoding at between 3 and 4 times the speed as compared to 159 * using the old (non-experimental) encoder. The disadvantage 160 * is that you will be using a new (and unproven) encoding 161 * routine.
