%%%%
%%%%  This package has the LPPL maintenance status `maintained' and is
%%%%  currently maintained by MSP:  contact@mathscipub.org 
%%%%
%%%%  It comprises the files: pinlabel.sty (this file) and the manual
%%%%  pinlabdoc.pdf where full documentation may be found, togther 
%%%%  with the source files for the documentation.
%%%% 
%%%% 
%%%%  pinlabel.sty  is designed for inserting perfectly formatted TeX
%%%%       labels in eps or pdf files for inclusion in documents.
%%%%       It uses the coordinates provided by ghostview (or gv) to
%%%%       position the label and reads the relevant bounding box
%%%%       information from the eps file (which must be provided: if
%%%%       your figure exists only as a pdf file, then run pdf2eps).
%%%%       Several features are provided which facilitate perfect 
%%%%       first-time label positioning, of which the most important
%%%%       is auto-spacing, which sets the label a predetermined gap
%%%%       away from the figure object which is being labelled.  The
%%%%       gap is \hair (a TeX dimension, preset to 3pt, but settable
%%%%       on the fly) and the direction of the spacing is chosen 
%%%%       automatically.  The result is consistent and eye-pleasing
%%%%       spacing.
%%%%       In use, read the position of the object that you wish to
%%%%       label and do not guess the position of the actual label.
%%%%       Then choose the orientation of the label (eg [tr] which
%%%%       means top-right) and the label will automatically be set
%%%%       so that top-right of the label bounding box is set one  
%%%%       \hair away from the object being labelled.
%%%%       
%%%%       
%%%%  pinlabel.sty  was written specifically for the use of editors and  
%%%%       authors of MSP papers and is the recommended package for
%%%%       use for labelling diagrams for MSP.
%%%%        
%%%%  pinlabel.sty  is a revised version of geomsfig.sty with improved 
%%%%       functionality and simpler syntax.  The old syntax remains
%%%%       available for backwards compatibility, see below.
%%%% 
%%%%  new syntax: \pinlabel {label} by x-pin y-pin at x-location y-location
%%%%       and   \pinlabel* {label} by x-pin y-pin at x-location y-location
%%%% 
%%%%       where "x-pin y-pin" is the point in intrinsic coords in label
%%%%       space where we are placing the pin and "x-location y-location" 
%%%%       is the point in diagram space (in PS points as read in gv) where
%%%%       the label is pinned.  \pinlabel uses \hair autospacing \pinlabel*
%%%%       does not.  See the manual for full details. 
%%%%       \mathsurround is set to 0pt for parsing the label
%%%% 
%%%%  options:  "by x-pin y-pin" may be omitted the default is 0 0
%%%%       orientation commands [r], [l] etc may replace "by x-pin y-pin"
%%%%                            [r] is right-centre (same as "by 0 1") etc
%%%%       a manual adjustment "<x-adj, y-adj>" may be added before "at"
%%%%       or directly after the label
%%%%          
%%%%  Examples  \pinlabel $a^b$ [l] <-2pt,1pt> at 231 47 
%%%%  Same as   \pinlabel $a^b$ by -1 0  <-2pt,1pt> at 231 47 
%%%%  Same as   \pinlabel $a^b$ <-2pt,1pt> [l] at 231 47 
%%%%  Same as   \pinlabel $a^b$ <-2pt,1pt> by -1 0  at 231 47 
%%%%           
%%%%           which pins "$a^b$" by centre-left at 231 47 with two 
%%%%           adjustments: \hair (autospacing) and then (-2pt,1pt) manual
%%%%
%%%%           \pinlabel* {A nice figure} [Bl] <-5pt,0pt> at 231 47 
%%%%           
%%%%           which pins "A nice figure" by baseline-left at 231 47  
%%%%           with one adjustment: (-5pt,0pt)
%%%%
%%%%  Full list of orientation commands:  r=right, l=left, t=top, b=bottom
%%%%       and B=baseline,  default is centre and any sensible combination 
%%%%       of two commands may be give (in either order) eg 
%%%%       [tl]=[lt]=top-left of label bounding box
%%%% 
%%%%  NB the commands are syntax sensitive and use spaces as separators so
%%%%       they DON'T work with \obeyspaces set.    Braces must be placed 
%%%%       around labels containing spaces but may be omitted if there are
%%%%       no spaces in the label code (see the examples above and below).
%%%%
%%%%  Label instructions go either in the file inside \labellist 
%%%%       ... \endlabellist  or in a separate .lab file (ie if fig 
%%%%       is fig4-1.eps or .ps, then labels go in \figdir/fig4-1.lab 
%%%%       where \figdir/ is the directory containing fig4-1.eps).  
%%%%       The \labellist overrides a .lab file.
%%%%       \labellist ... \endlabellist can be given at any time before 
%%%%       the next figure, but typically will be included in the figure 
%%%%       code, as in the following example.
%%%%
%%%%  Here is a complete example of a relabelled figure:
%%%%
%%%%          \begin{figure}[ht!]
%%%%          \labellist\small\hair 2.5pt
%%%%          \pinlabel {$\partial _1 X$} by 1 0 at 156 426
%%%%          \pinlabel {$\partial _2 X$} by -1 1 at 334 429
%%%%          \pinlabel $X_1$ at 431 513 
%%%%          \pinlabel $X_2$ at 428 460 
%%%%          \pinlabel $H_X$ [lb] at 311 622
%%%%          \pinlabel* $H_X'$ [tr] <-1.5pt,-2pt> at 178 370
%%%%          \endlabellist
%%%%          \centerline{\psfig{file=\figdir/decomp,width=3in}}
%%%%          \caption{Labelling the boundary components of $X$}
%%%%          \label{Fig:decomp}
%%%%          \end{figure}
%%%%
%%%%  The actual figure can be included by using either psfig or 
%%%%      graphicx.  psfig is used by the code, but graphicx 
%%%%      commands are translated automatically, so in the above
%%%%      example the alternative code:
%%%%
%%%%          \centerline{\includegraphics[width=3in]{\figdir/decomp}}
%%%%          
%%%%      would produce identical results.  Automatic translation ONLY  
%%%%      takes place is a labellist is present, so if you use a .lab
%%%%      file then you MUST use the psfig syntax.
%%%%          
%%%%          
%%%%                            VERY IMPORTANT   
%%%%                            ==============
%%%%      
%%%%      The file extension MUST NOT be given.  The program will find
%%%%      the correct file (\figdir/decomp.eps or .ps or .pdf).
%%%%      
%%%%      READ THE BUGS below before using \includegraphics with pinlabel.
%%%%      
%%%%          
%%%%  old syntax: \setlabel is unchanged (but \mathsurround is set to 0pt) 
%%%%       \setlabel* is a new variant which sets \hair to 0pt (no 
%%%%       autospacing) and an optional manual adjustment may be added
%%%%       eg:
%%%%
%%%%           \setlabel<-2pt,-1pt>{a^b}{321}{33}{1}{1}
%%%%           \setlabel*<-2pt,-1pt>{a^b}{321}{33}{1}{1}
%%%%           \setlabel{a^b}{321}{33}{1}{1}
%%%%           \setlabel*{a^b}{321}{33}{1}{1}
%%%%       
%%%%       the first uses autospacing and adds a (-2pt,-1pt) manual
%%%%       adjustment;  the second uses just the manual adjustment,
%%%%       the third just autospacing and the fourth nothing.
%%%%
%%%%       old and new syntax may be mixed in a label list and given 
%%%%       either in a .lab file or inside \labellist ... \endlabellist
%%%%
%%%%    ***Users of geomsfig note the change to \mathsurround.  If you 
%%%%       do not use it, there will be no change in label positioning.
%%%%       If you do, labels may move a small amount horizontally.***
%%%%
%%%% 
%%%% !!!NBNB label is in horizontal mode in new syntax and math mode in old!!!
%%%% 
%%%%
%%%%  BUGS:  NO spaces are permitted in the file argument of \psfig
%%%%      Autotranslation of \includegraphics[]{} means that no
%%%%      spaces are permitted in the file argument to \includegraphics
%%%%      Eg  \includegraphics[width=4in]{ foo } will produce errors,
%%%%      use \includegraphics[width=4in]{foo}.  Spaces are permitted
%%%%      with other arguments.
%%%%          
%%%%      Many of the options in graphicx are not supported.  The     
%%%%      supported ones are:  width, height, scale, bbllx, bblly
%%%%      bburx, bbury and clip.  The syntax for clip is "clip=".
%%%%      Replace "keepaspectratio=true" by "proportional=".
%%%%      
%%%%      The command \reallyincludegraphics will force the use of
%%%%      graphicx (ie cancel autotranslation).  Since code will use 
%%%%      graphicx automatically if there is no labellist present, 
%%%%      \reallyincludegraphics will only be needed if a labellist 
%%%%      has already been given for a later figure.
%%%%     
%%%%      \graphicspath{} is not supported.  Use \figdir instead.
%%%%              
%%%%
%%%%     Automatic configuration for dvips and pdflatex is included 
%%%%     in this file.  No support is provided for other drivers.
%%%% 
%%%%     NB \psfig ouputs a vbox, which is not centred in latex' {center} 
%%%%     environment.  Either use \centerline{} or type \leavevmode
%%%%     before \psfig{..}.  The translator adds \leavevmode for 
%%%%     \includegraphics, which therefore centres correctly as usual
%%%%     in the {center} environment.
%%%%
%%%%  PLAIN TeX compatibility:  uses miniltx.tex and works with dvips 
%%%%     but NOT with pdftex.  For pdf output from plain TeX use dvips 
%%%%     followed by ps2pdf.
