+% ======================================================================
|
|
|
+% Modification History:
|
|
|
+%
|
|
|
+% 9 Oct 1990 JDS used more robust bbox reading code from Tom Rokicki
|
|
|
+% 29 Mar 1991 JDS implemented rotation= option
|
|
|
+% 25 Jun 1991 RR if bb specified on cmd line don't check
|
|
|
+% for .ps file.
|
|
|
+% 3 Jul 1991 JDS check if file already read in once
|
|
|
+% 4 Sep 1991 JDS fixed incorrect computation of rotated
|
|
|
+% bounding box
|
|
|
+% 25 Sep 1991 GVR expanded synopsis of \psfig
|
|
|
+% 14 Oct 1991 JDS \fbox code from LaTeX so \psdraft works with TeX
|
|
|
+% changed \typeout to \ps@typeout
|
|
|
+% 17 Oct 1991 JDS added \psscalefirst and \psrotatefirst
|
|
|
+% 23 Jun 1993 KHC ``doclip'' must appear before ``rotate''
|
|
|
+% 27 Oct 1993 TJD removed printing of filename to avoid
|
|
|
+% underscore problems. changed \frame to \fbox.
|
|
|
+% Added OzTeX support from BG. Added new
|
|
|
+% figure search path code from GT.
|
|
|
+% 01 Feb 2010 JRMT implemented the use of .eps figure format
|
|
|
+%
|
|
|
+% ======================================================================
|
|
|
+%
|
|
|
+% Command synopsis:
|
|
|
+%
|
|
|
+% \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.
|
|
|
+%
|
|
|
+% \psfigurepath{dir:dir:...} sets the path to search for the figure
|
|
|
+%
|
|
|
+% \psfig
|
|
|
+% usage: \psfig{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. If these four values are specified
|
|
|
+% *before* the "file" option, the PSFIG will not try to
|
|
|
+% open the PostScript file.
|
|
|
+% "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.
|
|
|
