Once a - * rotation angle was set by the auto rotate check, it was - * retained for all pages that followed instead of being - * retested for each page. - * - * 2010-Sep-17 - * Richard Nolde: Reinstate code from Feb 2009 that never got - * accepted into CVS with major modifications to handle -H and -W - * options. Replaced original PlaceImage function with several - * new functions that make support for multiple output pages - * from a single image easier to understand. Added additional - * warning messages for incompatible command line options. - * Add new command line options to specify PageOrientation - * Document Structuring Comment for landscape or portrait - * and code to determine the values from ouput width and height - * if not specified on the command line. - * Add new command line option to specify document creator - * as an alterntive to the string "tiff2ps" following model - * of patch submitted by Thomas Jarosch for specifiying a - * document title which is also supported now. - * - * 2009-Feb-11 - * Richard Nolde: Added support for rotations of 90, 180, 270 - * and auto using -r <90|180|270|auto>. 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. The auto opption rotates the image 90 degrees ccw to - * produce landscape if that is a better fit than portait. - * - * Cleaned up code in TIFF2PS and broke into smaller functions - * to simplify rotations. - * - * Identified incompatible options and returned errors, eg - * -i for imagemask operator is only available for Level2 or - * Level3 Postscript in the current implmentation since there - * is a difference in the way the operands are called for Level1 - * and there is no function to provide the Level1 version. - * -H was not handled properly if -h and/or -w were specified. - * It should only clip the masked images if the scaled image - * exceeds the maxPageHeight specified with -H. - * - * New design allows for all of the following combinations: - * Conversion of TIFF to Postscript with optional rotations - * of 90, 180, 270, or auto degrees counterclockwise - * Conversion of TIFF to Postscript with entire image scaled - * to maximum of values spedified with -h or -w while - * maintaining aspect ratio. Same rotations apply. - * Conversion of TIFF to Postscript with clipping of output - * viewport to height specified with -H, producing multiple - * pages at this height and original width as needed. - * Same rotations apply. - * Conversion of TIFF to Postscript with image scaled to - * maximum specified by -h and -w and the resulting scaled - * image is presented in an output viewport clipped by -H height. - * The same rotations apply. - * - * 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 a lot of the loop - * overhead of the byte-by-byte 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.
