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 output 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 specifying 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 portrait. * * 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 implementation 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 specified 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.
