% Extract the ASCII text from a PostScript file.  Nothing is displayed.
% Instead, ASCII information is written to stdout.  The idea is similar to
% Glenn Reid's `distillery', only a lot more simple-minded, and less robust.

% If SIMPLE is defined, just the text is written, with a guess at line
% breaks and word spacing.  If SIMPLE is not defined, lines are written
% to stdout as follows:
%
%	F <height> <width> (<fontname>)
%		Indicate the font height and the width of a space.
%
%	P
%		Indicate the end of the page.
% 
%	S <x> <y> (<string>) <width>
%		Display a string.
%
% <width> and <height> are integer dimensions in units of 1/720".
% <x> and <y> are integer coordinates, in units of 1/720", with the origin
%   at the lower left.
% <string> and <fontname> are strings represented with the standard
%   PostScript escape conventions.

% If COMPLEX is defined, the following additional types of lines are
% written to stdout.
%
%	C <r> <g> <b>
%		Indicate the current color.
%
%	I <x> <y> <width> <height>
%		Note the presence of an image.
%
%	R <x> <y> <width> <height>
%		Fill a rectangle.
%
% <r>, <g>, and <b> are RGB values expressed as integers between 0 and 1000.
%
% Note that future versions of this program (in COMPLEX mode) may add
%   other output elements, so programs parsing the output should be
%   prepared to ignore elements that they do not recognize.

% Note that this code will only work in all cases if systemdict is writable
% and if `binding' the definitions of operators defined as procedures
% is deferred.  For this reason, it is normally invoked with
%	gs -q -dNODISPLAY -dDELAYBIND -dWRITESYSTEMDICT ps2ascii.ps

% Thanks to:
%    J Greely <jgreely@cis.ohio-state.edu> for improvements to this code;
%    Jerry Whelan <jerryw@abode.ccd.bnl.gov> for motivating other improvements;
%    David M. Jones <dmjones@theory.lcs.mit.edu> for improvements noted below.

%%  Additional modifications by David M. Jones
%%  (dmjones@theory.lcs.mit.edu), December 23, 1997
%%  
%%  (a) Rewrote forall loop at the end of .show.write.  This fixes a
%%      stack leakage problem, but the changes are more significant
%%      than that.  
%% 
%%      .char.map includes the names of all characters in the
%%      StandardEncoding, ISOLatin1Encoding, OT1Encoding and
%%      T1Encoding vectors.  Thus, if the Encoding vector for the
%%      current font contains a name that is not in .char.map, it's
%%      redundant to check if the Encoding vector is equal to one of
%%      the known vectors.  Previous versions of ps2ascii would give
%%      up at this point, and substitute an asterisk (*) for the
%%      character.  I've taken the liberty of instead using the
%%      OT1Encoding vector to translate the character, on the grounds
%%      that in the cases I'm most interested in, a font without a
%%      useful Encoding vector was most likely created by a DVI to PS
%%      converter such as dvips or DVILASER (and OT1Encoding is
%%      largely compatible with StandardEncoding anyway).  [Note that
%%      this does not make my earlier changes to support dvips (see
%%      fix (a) under my 1996 changes) completely obsolete, since
%%      there's additional useful information I can extract in that
%%      case.]
%%      
%%      Overall, this should provide better support for some documents
%%      (e.g, DVILASER documents will no longer be translated into a
%%      series of *'s) without breaking any other documents any worse
%%      than they already were broken.
%% 
%%  (b) Fixed two bugs in dvips.df-tail: (1) changed "dup 127" to "dup
%%      128" to fix fencepost error, and (2) gave each font it's own
%%      FontName rather than having all fonts share the same name.
%%  
%%  (c) Added one further refinement to the heuristic for detecting
%%      paragraph breaks: do not ever start a new paragraph after a
%%      line ending in a hyphen.
%% 
%%  (d) Added a bunch of missing letters from the T1Encoding,
%%      OT1Encoding and ISOLatin1Encoding vectors to .letter.chars to
%%      improve hyphen-elimination algorithm.  This still won't help
%%      if there's no useful Encoding vector.
%% 
%%  NOTE: A better solution to the problem of missing Encoding vectors
%%  might be to redefine definefont to check whether the Encoding
%%  vector is sensible and, if not, replace it by a default.  This
%%  would alleviate the need for constant tests in the .show.write
%%  loop, as well as automatically solving the problem noted in fix
%%  (d) above, and the similar problem with .break.chars.  This should
%%  be investigated.  Also, the hyphen-elimination algorithm really
%%  needs to be looked at carefully and rethought.

%%* Modifications to ps2ascii.ps by David M. Jones
%%* (dmjones@theory.lcs.mit.edu), June 25-July 8, 1996

%%* Modifications:
%%* 
%%* (a) added code to give better support for dvips files by providing
%%*     FontBBox's, FontName's and Encoding vectors for downloaded
%%*     bitmap fonts.  This is done by using dvips's start-hook to
%%*     overwrite the df-tail and D procedures that dvips uses to
%%*     define its Type 3 bitmap fonts.  Thus, this change should
%%*     provide better support for dvips-generated PS files without
%%*     affecting the handling of other documents.
%%* 
%%* (b) Fixed two bugs that could potentially affect any PS file, not
%%*     just those created by dvips: (1) added missing "get" operator
%%*     in .show.write and (2) fixed bug that caused a hyphen at the
%%*     end of a line to be replaced by a space rather than begin
%%*     deleted.  Note that the first bug was a source of stack
%%*     leakage, causing ps2ascii to run out of operand stack space
%%*     occasionally.
%%* 
%%*     Search for "%%* BF" to find these modifications.
%%*     
%%* (c) Improved the heuristic for determining whether a line break
%%*     has occurred and whether a line break represents a paragraph
%%*     break.  Previously, any change in the vertical position caused
%%*     a line break; now a line break is only registered if the
%%*     change is larger than the height of the current font.  This
%%*     means that superscripts, subscripts, and such things as
%%*     shifted accents generated by TeX won't cause line breaks.
%%*     Paragraph-recognition is now done by comparing the indentation
%%*     of the new line to the indentation of the previous line and by
%%*     comparing the vertical distance between the new line and the
%%*     previous line to the vertical distance between the previous
%%*     line and its predecessor.
%%*     
%%* (d) Added a hook for renaming the files where stdout and stderr
%%*     go.
%%* 
%%* In general, my additions or changes to the code are described in
%%* comments beginning with "%%*".  However, there are numerous other
%%* places where I have either re-formatted code or added comments to
%%* the code while I was trying to understand it.  These are usually
%%* not specially marked.

%%* Define the OT1Encoding and T1Encoding vectors for use with dvips
%%* files.  Unfortunately, there's no way of telling what font is
%%* really being used within a dvips document, so we can't provide an
%%* appropriate encoding for each individual font.  Instead, we'll
%%* just provide support for the two most popular text encodings, the
%%* OT1 and T1 encodings, and just accept the fact that any font not
%%* using one of those encodings will be rendered as gibberish.
%%* 
%%* OT1 is Knuth's 7-bit encoding for the CMR text fonts, while T1
%%* (aka the Cork encoding) is the 8-bit encoding used by the DC
%%* fonts, a preliminary version of the proposed Extended Computer
%%* Modern fonts.  Unfortunately, T1 is not a strict extension of OT1;
%%* they differ in positions 8#000 through 8#040, 8#074, 8#076, 8#134,
%%* 8#137, 8#173, 8#174, 8#175 and 8#177, so we can't use the same
%%* vector for both.
%%* 
%%* Of course, we also can't reliably tell the difference between an
%%* OT1-encoded font and a T1-encoded font based on the information in
%%* a dvips-created PostScript file.  As a best-guess solution, we'll
%%* use the T1 encoding if the font contains any characters in
%%* positions above 8#177 and the OT1 encoding if it doesn't.
