greid@adobe.com (Glenn Reid) (06/08/89)
Thanks for all your comments and bug files from the last release of the
Distillery. Here is the latest release, which I think fixes most of
the bugs reported. There was one file that I couldn't fix that was
combining user-defined fonts with Times fonts in strange ways to form
Hebrew characters (I think) that still confuses the distillery. Other
than that, I hope it is pretty robust at this point. As usual, bug
reports, comments, and encouragement should be sent to greid@adobe.COM
Thanks,

% OVERVIEW:
% This is a meta-utility program that "distills" any PostScript
% language program into a simpler one. The resulting program
% will print exactly the same page as the original, but all
% unnecessary execution overhead is eliminated and the file is
% clean, uniform, and fast.
%
% RELEASE NOTES: [recent changes and details]
% First public release: 2/10/89
% Second release (numbered release 8): 2/17/89

% Release 9: 3/2/89
% - fixed color-induced [major efficiency loss] bug
% - produces %%BoundingBox and %%PageBoundingBox info (atend)
% - works better (bugs fixed) on rotated (landscape) documents

%
% MANY USES:
% * If you archive documents in PostScript format, they can often
% be made more compact and efficient by distilling them.
% * As a development tool, you can see what your program is
% really doing, and how simple and fast the driver could be.
% * Distilled files can be used as an interchange format,
% since arbitrary PostScript files can be converted to this
% uniform representation.
% * If your program can parse distilled files, then any arbitrary
% PostScript program can be used as input after distilling.
% * Many others.
%
% FEATURES:
% * correctly distills arbitrarily complex PostScript programs
% * output is universal, simple, and in default user coordinates
% * handles "charpath", "image", "imagemask", "awidthshow", etc.
% * correctly follows "save", "restore", "gsave", "grestore"
% * re-encodes fonts automatically to match application encoding
% * reduces prologue size to only about 25-30 lines
% * For machine-generated code:
% * output files are almost always SMALLER than original files
% * output files are almost always FASTER than original files
% * optimizes "show" to use "widthshow" whenever possible.
% * uses save/restore at page boundaries
% * observes structuring conventions and page independence
% * caches font dictionaries instead of repeating "findfonts"
% * output is normally VERY fast.
%
% HOW TO USE:
% This program redefines a bunch of operators, and is invoked
% with the word "distill". This file has to precede the job it is
% distilling, and you have to invoke it by calling "distill".
%
% PRINTERS:
% In general, start with this file (still.ps), add the word
% "distill" at the end (to invoke the procedure), and tack
% any PostScript language file onto the end. Send this to
% your favorite PostScript printer with an appropriate
% end-of-file indication at the end. Results will
% be returned across communication channel, often to a log
% file somewhere (Unix: /usr/adm/printername.log)
%
% INTERPRETERS: if you have an interpreter with a file system
% handy, first type "(still.ps) run" to load this file, then
% distill your file like this: "(prog.ps) distill". It will
% write the results in "prog.psx" (appends an x to the file
% name you give it).
%
% MACINTOSH: I have written a small Mac utility that is called
% "DistillPS" (an adaptation of "SendPS") that will perform the
% above PRINTER steps for you. If you are an Adobe registered
% developer, you can get a copy directly from Adobe (or see
% posting in USENET comp.binaries.mac group).
%
% BACKGROUND
% The basic idea is to execute the input file completely, with all of
% the painting operators redefined. When one of these operators is
% called by the client program, the distillery will write the
% path the output file (with all coordinates normalized to the default
% userspace coordinate system). Note that it will usually take LONGER
% to distill a file than it would to print it, because it executes the
% whole program, and much of it in a redefined state (slower). Usually
% only about 20% slower than original print time to distill.
%
% The routines in this file are broken down into several areas. Most
% of them are concerned with writing things to the output file,
% actually, although there are two other interesting areas. The first
% are the graphics state procedures, which attempt to keep track of the
% graphics state and, when a painting op is called, it writes out any
% changes to the graphics state since the last time it was called. This
% keeps each painting op from having to write gstate itself. The other
% interesting procs are simply the redefinitions of the painting ops
% themselves.
%
% KNOWN COMPATIBLE PROGRAMS
% The following applications have been tested (with some version of the
% driver, at least), successfully:
% Lotus Manuscript
% Macintosh "LaserPrep" (all documents, I think)
% DEC's VaxDocument
% Scribe
% PageMaker
% Frame Maker
% Adobe Illustrator
% TranScript (ditroff and enscript drivers)
% Pedigree Plot package (incomplete testing)
%
% KNOWN PROBLEMS:
% Clipping isn't handled correctly.
%
% The bounding box for text is a crude estimate.
%
% Some font tricks are difficult or impossible to distill correctly.
% Especially those that involve sharing various parts of a font
% between different font dictionaries, or changing the contents
% of a font after "definefont" has been executed. Luckily there
% aren't many programs that do things like that.
%
% Hand-written PostScript language programs (especially those
% that take advantage of looping constructs) may get BIGGER
% when you distill them, because the Distillery unrolls all loops.
% It is really intended for machine-generated files, but it should
% still work on programs tightly coded by hand (like Cookbook
% examples).
%
% Use of the "put" and "putinterval" operators to overwrite
% string bodies can confuse the optimization technique. If you
% see strange output (wrong characters printed, especially),
% try changing "/optimize true def" to "/optimize false def"
% at the very beginning of this program.
%
% Programs that use the "transform" operator to make resolution-
% rounding decisions may have the output file bound to a specific
% resolution. The last ProcSet (called "hacks") redefines a few
% operators to try to work around this. Output file is still
% device-independent in any case, but might look different.
%
% Distillery relies on bug in save/restore related to string bodies
% to preserve some information across save/restore. It is localized
% to the "adobe_staticvar" procedure set, but may not always work.
%
% In order to optimize re-encoding of fonts, the distillery takes
% an educated guess that the first re-encoded font it sees will
% have a representative encoding vector ("stdvec"). If this
% first font is not encountered before other marks are made, the encoding
% vector cannot be produced in the %%BeginSetup section, and the still
% is forced to repeat the vector every time a font is used. Work
% is in progress on a heuristic to improve this.
%
% In order to avoid building up the dictionary stack during
% execution, all definitions are made in one dictionary
% (PROLOGUE) and it is not explicitly brought to the top of
% the dictionary stack for each operation (to avoid
% "dictstackoverflow" errors). Most of the identifiers have
% been chosen to be reasonably unique, but there could be a
% conflict if user programs use the same names.
%
% Sometimes generates unnecessarily verbose code in the presence
% of lots of save/restores in original file. Try distilling the
% output a second time to improve this (like whiskey)....
%
% Some of the ProcSets depend on each other in weird ways, which
% is wrong, since only the script should depend on the procset
% definitions. Eventually this will get fixed.
%
% Does not always work correctly with user-defined fonts, especially
% those defined by the standard TeX driver (unfortunately). In
% particular, TeX bitmap fonts that are defined and have characters
% added on the fly are almost impossible to deal with reliably in this
% distillery approach.
%%BeginProcSet: originals 0.5 0
% This dictionary contains the original definitions of native operators
% that have been redefined by the Distillery. They are needed on
% occasion to permit the original program to execute operators without
% having the results distilled. The motivating factor for this is
% user-defined fonts, which "draw" into the font cache, but the effects
% are not wanted in the output file.
%
% This also serves as a list of the redbook operators that are redefined
% by the distillery code.
