#'# Fix emacs syntax highlighting
# foomatic-rip is a spooler-independent filter script which takes
# PostScript as standard input and generates the printer's page
# description language (PDL)/raster format as standard output. This
# kind of filter is usually called Raster Image Processor (RIP),
# therefore the name "foomatic-rip".
# Save it in one of the directories of your $PATH, so that it gets
# found when called from the command line (for spooler-less printing),
# link it to spooler-specific directories when you use CUPS or PPR:
# ln -s /usr/bin/foomatic-rip /usr/lib/cups/filter/
# ln -s /usr/bin/foomatic-rip /usr/lib/ppr/lib/
# ln -s /usr/bin/foomatic-rip /usr/lib/ppr/interfaces/
# Mark this filter world-readable and world-executable (note that most
# spoolers run the print filters as a special user, as "lp", not as
# "root" or as the user who sent the job).

# the page accounting information which CUPS needs on standard
# error.
# Redesign by Helge Blischke (2004-11-17):
# - As the PostScript job itself may define BeginPage and/or EndPage
# procedures, or the alternate pstops filter may have inserted
# such procedures, we make sure that the accounting routine
# will safely coexist with those. To achieve this, we force
# - the accountint stuff to be inserted at the very end of the
# PostScript job's setup section,
# - the accounting stuff just using the return value of the
# existing EndPage procedure, if any (and providing a default one
# if not).
# - As PostScript jobs may contain calls to setpagedevice "between"
# pages, e.g. to change media type, do in-job stapling, etc.,
# we cannot rely on the "showpage count since last pagedevice
# activation" but instead count the physical pages by ourselves
# (in a global dictionary).

## to apply option settings given by the command line and to set
## the defaults given in the PPD file.
# Examination strategy: read lines from STDIN until the first
# %%Page: comment appears and save them as @psheader. This is the
# page-independent header part of the PostScript file. The
# PostScript interpreter (renderer) must execute this part once
# before rendering any assortment of pages. Then pages can be
# printed in any arbitrary selection or order. All option
# settings we find here will be collected in the default option
# set for the RIP command line.
# Now the pages will be read and sent to the renderer, one after
# the other. Every page is read into memory until the
# %%EndPageSetup comment appears (or a certain amount of lines was
# read). So we can get option settings only valid for this
# page. If we have such settings we set them in the modified
# command set for this page.
# If the renderer is not running yet (first page) we start it with
# the command line built from the current modified command set and
# send the first page to it, in the end we leave the renderer
# running and keep input and output pipes open, so that it can
# accept further pages. If the renderer is still running from
# the previous page and the current modified command set is the
# same as the one for the previous page, we send the page. If
# the command set is different, we close the renderer, re-start
# it with the command line built from the new modified command
# set, send the header again, and then the page.
# After the last page the trailer (%%Trailer) is sent.
# The output pipe of this program stays open all the time so that
# the spooler does not assume that the job has finished when the
# renderer is re-started.
# Non DSC-conforming documents will be read until a certain line
# number is reached. Command line or JCL options inserted later
# will be ignored.
# If options are implemented by PostScript code supposed to be
# stuffed into the job's PostScript data we stuff the code for all
# these options into our job data, So all default settings made in
# the PPD file (the user can have edited the PPD file to change
# them) are taken care of and command line options get also
# applied. To give priority to settings made by applications we
# insert the options's code in the beginnings of their respective
# sections, so that sommething, which is already inserted, gets
# executed after our code. Missing sections are automatically
# created. In non-DSC-conforming files we insert the option code
# in the beginning of the file. This is the same policy as used by
# the "pstops" filter of CUPS.
# If CUPS is the spooler, the option settings were already
# inserted by the "pstops" filter, so we don't insert them
# again. The only thing we do is correcting settings of numerical
# options when they were set to a value not available as choice in
# the PPD file, As "pstops" does not support "real" numerical
# options, it sees these settings as an invalid choice and stays
# with the default setting. In this case we correct the setting in
# the first occurence of the option's code, as this one is the one
# added by CUPS, later occurences come from applications and
# should not be touched.
# If the input is not PostScript (if there is no "%!" after
# $maxlinestopsstart lines) a file conversion filter will
# automatically be applied to the incoming data, so that we will
# process the resulting PostScript here. This way we have always
# PostScript data here and so we can apply the printer/driver
# features described in the PPD file.
# Supported file conversion filters are "a2ps", "enscript",
# "mpage", and spooler-specific filters. All filters convert
# plain text to PostScript, "a2ps" also other formats. The
# conversion filter is always used when one prints the
# documentation pages, as they are created as plain text,
# when CUPS is the spooler "pstops" is executed after the
# filter so that the default option settings from the PPD file
# and CUPS-specific options as N-up get applied. On regular
# printouts one gets always PostScript when CUPS or PPR is
# the spooler, so the filter is only used for regular
# printouts under LPD, LPRng, GNUlpr or without spooler.

# We buffer the data only as long as we didn't determing which filters to
# use for this piece of data and with which options. There are no temporary
# files used.
# foomatic-rip splits into up to 6 parallel processes to do the whole
# filtering (listed in the order of the data flow):
# KID0: Generate documentation pages (only jobs with "docs" option)
# KID2: Put together already read data and current input stream for
# feeding into the file conversion filter (only non-PostScript
# and "docs" jobs)
# KID1: Run the file conversion filter to convert non-PostScript
# input into PostScript (only non-PostScript and "docs" jobs)
# MAIN: Prepare the job auto-detecting the spooler, reading the PPD,
# extracting the options from the command line, and parsing
# the job data itself. It analyses the job data to check
# whether it is PostScript and starts KID1/KID2 if not, it
# also stuffs PostScript code from option settings into the
# PostScript data stream. It starts the renderer (KID3/KID4)
# as soon as it knows its command line and restarts it when
# page-specific option settings need another command line
# or different JCL commands.
# KID3: The rendering process. In most cases GhostScript, "cat"
# for native PostScript printers with their manufacturer's
# PPD files.
# KID4: Put together the JCL commands and the renderer's output
# and send all that either to STDOUT or pipe it into the
# command line defined with $postpipe.
## This function runs the renderer command line (and if defined also
## the postpipe) and returns a file handle for stuffing in the
