- * 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.
