 * Revision history
 *
 * 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 alot of the loop
 *    overhead of the byte-by-bye 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.
