It works 28%%% by finding the bounding box comment, 29%%% calculating the correct scale values, and 30%%% inserting a vbox of the appropriate size at 31%%% the current position in the TeX document. 32%%% 33%%% To use, simply use 34%%% 35%%% \input epsf % somewhere early on in your TeX file 36%%% 37%%% % then where you want to insert a vbox for a figure: 38%%% \epsfbox{filename.ps} 39%%% 40%%% Alternatively, you can supply your own 41%%% bounding box by 42%%% 43%%% \epsfbox[0 0 30 50]{filename.ps} 44%%% 45%%% This will not read in the file, and will 46%%% instead use the bounding box you specify. 47%%% 48%%% The effect will be to typeset the figure as 49%%% a TeX box, at the point of your \epsfbox 50%%% command. By default, the graphic will have 51%%% its `natural' width (namely the width of 52%%% its bounding box, as described in 53%%% filename.ps). The TeX box will have depth 54%%% zero. 55%%% 56%%% You can enlarge or reduce the figure by 57%%% using 58%%% 59%%% \epsfxsize = <dimen> \epsfbox{filename.ps} 60%%% or 61%%% \epsfysize = <dimen> \epsfbox{filename.ps} 62%%% 63%%% instead. Then the width of the TeX box will 64%%% be \epsfxsize and its height will be scaled 65%%% proportionately (or the height will be 66%%% \epsfysize and its width will be scaled 67%%% proportionately). 68%%% 69%%% The width (and height) is restored to zero 70%%% after each use, so \epsfxsize or \epsfysize 71%%% must be specified before EACH use of 72%%% \epsfbox. 73%%% 74%%% A more general facility for sizing is 75%%% available by defining the \epsfsize macro. 76%%% Normally you can redefine this macro to do 77%%% almost anything. The first parameter is 78%%% the natural x size of the PostScript 79%%% graphic, the second parameter is the 80%%% natural y size of the PostScript graphic. 81%%% It must return the xsize to use, or 0 if 82%%% natural scaling is to be used. Common uses 83%%% include: 84%%% 85%%% \epsfxsize % just leave the old value alone 86%%% 0pt % use the natural sizes 87%%% #1 % use the natural sizes 88%%% \hsize % scale to full width 89%%% 0.5#1 % scale to 50% of natural size 90%%% \ifnum #1 > \hsize \hsize \else #1\fi 91%%% % smaller of natural, hsize 92%%% 93%%% If you want TeX to report the size of the 94%%% figure (as a message on your terminal when 95%%% it processes each figure), use 96%%% `\epsfverbosetrue'. 97%%% 98%%% If you only want to get the bounding box 99%%% extents, without producing any output boxes 100%%% or \special{}, then use \epsfgetbb{filename}. 101%%% The bounding box corner coordinates are saved 102%%% in the macros \epsfllx, \epsflly, \epsfurx, 103%%% and \epsfury in PostScript units of big 104%%% points. 105%%% 106%%% Revision history: 107%%% 108%%% --------------------------------------------- 109%%% epsf.tex macro file: 110%%% Originally written by Tomas Rokicki of 111%%% Radical Eye Software, 29 Mar 1989. 112%%% 113%%% --------------------------------------------- 114%%% Revised by Don Knuth, 3 Jan 1990. 115%%% 116%%% --------------------------------------------- 117%%% Revised by Tomas Rokicki, 18 Jul 1990. 118%%% Accept bounding boxes with no space after 119%%% the colon. 120%%% 121%%% --------------------------------------------- 122%%% Revised by Nelson H.
