+ * Revision history
+ * 2013-Jan-21
+ *    Richard Nolde: Fix bug in auto rotate option code. 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.  So user beware, you have been warned!

+/*****************************************************************************
+*
+* Name:         Ascii85EncodeBlock( ascii85_p, f_eod, raw_p, raw_l )
+*
+* Description:  This routine will encode the raw data in the buffer described
+*               by raw_p and raw_l into ASCII85 format and store the encoding
+*               in the buffer given by ascii85_p.
+*
+* Parameters:   ascii85_p   -   A buffer supplied by the caller which will
+*                               contain the encoded ASCII85 data.
+*               f_eod       -   Flag: Nz means to end the encoded buffer with
+*                               an End-Of-Data marker.
+*               raw_p       -   Pointer to the buffer of data to be encoded
+*               raw_l       -   Number of bytes in raw_p[] to be encoded
+*
+* Returns:      (int)   <   0   Error, see errno
+*                       >=  0   Number of bytes written to ascii85_p[].
+*
+* Notes:        An external variable given by A85BREAKCNTR is used to
+*               determine when to insert newline characters into the
+*               encoded data.  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.
