rpcl - converts PCL raster data to sprites
==========================================
This program converts black & white, CMY and CMYK PCL raster data into
sprites. It recognizes the format on its own and creates a sprite of the
appropriate colour depth (The palette might not be ideal at times. Well, you
can always fiddle it a bit). It understands compression types 0, 2 and 3 and
hence understands output produced by Acorn's PDumperLJ (LaserJet and DeskJet
printers) and the one patched by me (included in this release). I have tested
it with the following HP printer drivers:
- LaserJet 5
- DeskJet 600/C
- DeskJet 660C
They all work just fine. If others won't work just use these (after all this
is not dependent on what kind of printer you actually have).
This new version of rpcl doesn't stop after the first raster area it finds
but processes all of them and stores each in its own sprite file. If the
sprite-name you specify ends in a decimal string, sprites 2, ... will
be numbered accordingly, otherwise sprite 2 will have "001" appended and
the following ones will be numbered as one would expect.
So if you know there are multiple pages in the pcl file you better give
your sprite-name a number right away, e.g. ``rpcl <pcl-file> sprite001''.
Usage:
rpcl [options] infile outfile
Options:
-v Verbose mode - output information on the raster area
-w Give out warnings if there's anything within the raster area that's not
supposed to be there (characters). In that case the offending characters
are output.
-l# Set number of raster-lines you wish to cache. Default is 256, WimpSlot
will be extended if necessary.
This program is very useful if you want to test your printing code (no more wasting
of paper, just view the result on screen) or in case you need a sprite from one
of your (DTP-) documents.
In case you wish to keep the sprites for future viewing I recommend scaling them
down with ChangeFSI (1:4 is a good value) into a mode with a higher number of
colours (e.g. black/white into mode 27 or CMY(K) into mode 28). ChangeFSI will
smooth out the dithering/halftoning and antialias the image.
