% SPQR Jan 94
%
%%%--------------------------------------------------------------------
%%% psfig merged with EPSF = epsfig Release 1
%%% 1.0 November 91
%%% 1.1 Dec 91 fixed some bugs
%%% 1.2 Jan 92 fixed bug that it never stopped reading PS file until
%%% it reached the end! merged in changes from psfig1.8
%%% (plain TeX definition of \fbox, new code for rotation)
%%% 1.3 Jan 92 separated out \special code so that dvitops can be
%%% supported. use \psfigdriver{dvitops}%
%%% 1.4 Jan 92 fixed dvitops. need to input psfig at different point
%%% in dvips from dvitops. define \psfig@start and \psfig@end to cope
%%% with this
%%% 1.5 Jan 92 force use of psfig method if using dvitops
%%% 1.6 May 92 fixed bugs
%%% 1.7 Sep 92 added support for emtex, sort of. reads a .bb file
%%% and imports .pcx file. Boolean flag \epsfigdos used
%%% to indicate that we cannot have more than one . in the
%%% suffix (ie we will look at file.bb not file.eps.bb)
%%%
%%% 1.8 Sep 92 added support for OzTeX; fixed bugs in dvips support
%%% (including clipping to bounding box); removed use of dimen100.
%%%
%%% 1.9 Dec 92 cleaned up documentation again
%%% 1.10 Mar 93 cleaned up for plain TeX
%%% 1.11 Mar 93 merged in changes by Peter Galko (supplied by CERN) for
%%% use with Textures
%%% 1.12 Apr 93 actually *tested* the Textures additions, and so rewrote
%%% from scratch (borrowed an idea from psbox)
%%% 1.13 May 93 allow for file names with _ or $ in them in \psdraft, and
%%% fix problem that occurred with missing BoundingBox
%%% 1.14 May 93 allow for .z suffix
%%% 1.15 July 93 allow for .gz suffix
%%% use \leavevmode as appropriate
%%% fix plain \TeX mode
%%% (fixes from Peter-Klaus Schilling <R02SCH@DSYIBM.DESY.DE>)
%%% 1.16 August 93 [peta@mcrcim.mcgill.edu (Peter Whaite)]
%%% -- Implement Perl scripts to do compressed file inclusion and bb
%%% generation.
%%% -- Add \pscompress.
%%% -- Tidy up comments.
%%% 1.17 September 93 SPQR
%%% better code for literal name printing
%%% allowed for spaces around , and =
%%% 1.18 17.9.93
%%% updates to epsbb and epsfig from Peter W
%%% 1.19 14.11.93
%%% mistaken placement of calculation of EPS@Height resulted in errors
%%%
%--------------------------------------------------------
%%%
%%% code rearranged by Sebastian Rahtz (spqr@uk.ac.york.minster)
%%% from work by
%%% Trevor Darrell; Tom Rokicki; Daniel Smith; H. Payne, Robert Russell
%%%
%%% This is a version of Darrell's `psfig' macros which are designed
%%% to be used with dvips or dvitops, and the `epsf' macros (these are
%%% automaticaly included by the style file). I did this because the
%%% \special commands used by `epsf' appear to be more robust and
%%% portable than the raw \specials used by `psfig', but I preferred
%%% the psfig interface. This system preserves the psfig interface,
%%% but mainly uses epsf macros to carry out the job. The user
%%% interface is identical to \psfig, but you just use \epsfig
%%% instead. Rotation uses the original psfig macros: I could not work
%%% out how to do rotation with the epsf macros.
%%%
%%% The same applies to `rheight' and `rwidth'
%%%
%%% If you *really* want old psfig behaviour regardless, use \psfig. It is
%%% still there. Some of the features have gone, however. \figurepath
%%% seemed redundant, since it could be controlled by the TEXINPUTS
%%% variable anyway.
%%%
%%% As an added feature, if FILE cannot be found, a file called FILE.bb
%%% is searched for. This should simply contain a %%BoundingBox line. A perl
%%% script "epsbb" is provided to generate these automatically. It is
%%% assumed that if this exists, then the actual postscript is in UNIX
%%% compress format in FILE.Z or in GNU gzip format in FILE.gz or FILE.z.
%%%
%%% The macros then read the BB from FILE.bb, but insert "`epsfig FILE`" in
%%% the output for dvips to interpret (don't worry, it knows about this).
%%% "Epsfig" is another perl script which searches the TEXINPUTS path for
%%% FILE or FILE.{gz,z,Z}.
%%%
%%% As an added bonus if you say \pscompress the -c switch will be passed to
%%% epsfig, causing automatic FILE.bb generation and compression the first
%%% time dvips is run. Files in the system directories will NOT be
%%% compressed.
%%% If you are *not* on a Unix system and use this, deliberately or by
%%% mischance, you will have problems!
%%%
%%% This file can be included in a dumped format, or used as a LaTeX
%%% style file, or used in plain TeX. It does not load itself twice (I hope)

%%% GDH 7/26/87 -- changed so that it first looks in the local directory,

%%% --- SPQR 12.91 removed most of this to use epsf directly
%%%
%%% More modifications by J. Daniel Smith on 29 March 1991 to allow the
%%% the included PostScript figure to be rotated. The amount of
%%% rotation is specified by the "angle=" parameter of the \epsfig command.
%%%
%%% Modified by Robert Russell on June 25, 1991 to allow users to specify
%%% .ps filenames which don't yet exist, provided they explicitly provide
%%% boundingbox information via the \epsfig command. Note: This will only work
%%% if the "file=" parameter follows all four "bb???=" parameters in the
%%% command. This is due to the order in which psfig interprets these params.
%%% ---- SPQR 12.91 removed all this

%-----------------------------USAGE---------------------------------------
% From: gvr@cs.brown.edu (George V. Reilly)
%
% \psdraft draws an outline box, but doesn't include the figure
% in the DVI file. Useful for previewing.
%
% \psfull includes the figure in the DVI file (default).
%
% \psscalefirst width= or height= specifies the size of the figure
% before rotation.
% \psrotatefirst (default) width= or height= specifies the size of the
% figure after rotation. Asymetric figures will
% appear to shrink.
%
% usage: \epsfig{file=, figure=, height=, width=,
% bbllx=, bblly=, bburx=, bbury=,
% rheight=, rwidth=, clip=, angle=, silent=}%
%
% "file" is the filename. If no path name is specified and the
% file is not found in the current directory,
% it will be looked for in directory \psfigurepath.
% "figure" is a synonym for "file".
% By default, the width and height of the figure are taken from
% the BoundingBox of the figure.
% If "width" is specified, the figure is scaled so that it has
% the specified width. Its height changes proportionately.
% If "height" is specified, the figure is scaled so that it has
% the specified height. Its width changes proportionately.
% If both "width" and "height" are specified, the figure is scaled
% anamorphically.
% "bbllx", "bblly", "bburx", and "bbury" control the PostScript
% BoundingBox.
% "rheight" and "rwidth" are the reserved height and width
% of the figure, i.e., how big TeX actually thinks
% the figure is. They default to "width" and "height".
% The "clip" option ensures that no portion of the figure will
% appear outside its BoundingBox. "clip=" is a switch and
% takes no value, but the `=' must be present.
% The "angle" option specifies the angle of rotation (degrees, ccw).
% The "silent" option makes \psfig work silently.

%%%
%%% we need Rokicki's EPSF macros anyway:
%
% EPSF.TEX macro file:
% Written by Tomas Rokicki of Radical Eye Software, 29 Mar 1989.
% Revised by Don Knuth, 3 Jan 1990.
% Revised by Tomas Rokicki to accept bounding boxes with no
% space after the colon, 18 Jul 1990.
%
% TeX macros to include an Encapsulated PostScript graphic.
% Works by finding the bounding box comment,
% calculating the correct scale values, and inserting a vbox
% of the appropriate size at the current position in the TeX document.
%
% To use with the center environment of LaTeX, preface the \epsffile
% call with a \leavevmode. (LaTeX should probably supply this itself
% for the center environment.)
%
% To use, simply say
% \input epsf % somewhere early on in your TeX file
% \epsfbox{filename.ps} % where you want to insert a vbox for a figure
%
% Alternatively, you can type
%
% \epsfbox[0 0 30 50]{filename.ps} % to supply your own BB
%
% which will not read in the file, and will instead use the bounding
% box you specify.
%
% The effect will be to typeset the figure as a TeX box, at the
% point of your \epsfbox command. By default, the graphic will have its
% `natural' width (namely the width of its bounding box, as described
% in filename.ps). The TeX box will have depth zero.
%
% You can enlarge or reduce the figure by saying
% \epsfxsize=<dimen> \epsfbox{filename.ps}
% (or
% \epsfysize=<dimen> \epsfbox{filename.ps})
% instead. Then the width of the TeX box will be \epsfxsize and its
% height will be scaled proportionately (or the height will be
% \epsfysize and its width will be scaled proportiontally). The
% width (and height) is restored to zero after each use.
%
% A more general facility for sizing is available by defining the
% \epsfsize macro. Normally you can redefine this macro
% to do almost anything. The first parameter is the natural x size of
% the PostScript graphic, the second parameter is the natural y size
% of the PostScript graphic. It must return the xsize to use, or 0 if
% natural scaling is to be used. Common uses include:
%
% \epsfxsize % just leave the old value alone
% 0pt % use the natural sizes
% #1 % use the natural sizes
% \hsize % scale to full width
% 0.5#1 % scale to 50% of natural size
% \ifnum#1>\hsize\hsize\else#1\fi % smaller of natural, hsize
%
% If you want TeX to report the size of the figure (as a message
% on your terminal when it processes each figure), say `\epsfverbosetrue'.
