Then place each eps file +% in a \relabelbox ... \endrelabelbox with relabelling +% instructions after the \epsfbox{..} . +% +% The eps file is called exactly as usual with epsf.tex +% typical instructions being \epsfbox{filename.eps} +% and \epsfxsize dimension \epsfbox{filename.eps} +% (where "dimension" is the required finished width of +% the diagram). +% +% There are three (re)labelling macros: +% +% \relabel {pslabel}{TeX label} +% \adjustrelabel <dx,dy> {pslabel}{TeX label} +% \extralabel <x,y> {extra label} +% +% \relabel uses the ps file position for the new TeX +% label (which can be any TeX output). The new label +% is positioned with same reference point (left-hand +% end of baseline) as the original ps label. +% \adjustrelabel adjusts the position by dx,dy and +% is useful for fine tuning the position of the +% new label. \extralabel allows extra TeX labels to be +% inserted. The positions x,y are measured from the +% bottom right-hand corner of the box (so x is typically +% negative) ! The re/extra-labelling instructions can +% be given in any order and any TeX dimensions can +% be used for x,y,dx,dy. +% +% The result is a box of dimensions the original epsbox +% but with new TeX labels. This can then be inserted in +% $$ ... $$ or \centerline{ ... } for display, or +% combined with other boxes to form a larger display. +% +% The \relabelbox ... \endrelabelbox forms a TeX group; +% thus instructions for resizing text for the new labels +% (eg \small ) will remain local to this group. +% +% There are two main uses for the package : +% +% (1) Creating graphics with TeX labels : +% Draw the graphic with dummy ps labels (all different and in +% some common font eg Times-Roman). Then use \relabel 'ling +% instructions to replace the dummy labels by the genuine TeX +% labels. Use roughly the same size dummy labels as the final +% TeX labels and then the position will probably be perfect +% first time. Adjust the positions if necessary by editing +% \relabel to \adjustrelabel with appropriate <dx,dy>. +% +% (2) Editing the ps labels in an existing eps file to TeX +% labels : +% Use \relabel and \adjustrelabel to replace the +% existing labels. You may have to use \extralabel for +% some of the new labels (or to edit the eps file to change +% repeated ps labels to be different), see note (2) below. +% +% Notes: +% (1) All ps labels are removed whether or not +% instructions for relabelling are given. +% (2) If the eps file has two or more labels the +% same, then only one will be replaced. Therefore +% if you are designing a diagram from scratch then +% use different temporary ps labels for your labels +% even if you wish them to finish the same. If +% you are relabelling an existing eps diagram with TeX +% labels then use \extralabel's to replace the other +% label(s) or edit the eps file to change the repeated +% labels to different ones. +% (3) The macros are sensitive to extra spaces and +% the above syntax should be used. +% (4) The output will not view correctly on a dvi +% viewer which will typically show the new labels +% superimposed at the bottom right-hand corner. +% However those produced by \extralabel will be shown +% correctly positioned. +% +% A typical example of use is appended. More realistic +% examples are given in the postscript documentation file +% rlepsdoc.ps. CPR 16-12-96 +% +% +\input epsf +% +% Initialise for MTG control +% +\special{!
