- % Modified by J. Daniel Smith on 9 October 1990 to accept the
- % %%BoundingBox: comment with or without a space after the colon. Stole
- % file reading code from Tom Rokicki's EPSF.TEX file (see below).
- %
- % 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 \psfig 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 \psfig 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.
- %
- % 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
- %
-
- % 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.
- %
- % \psfigurepath#1 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.
- %
-
- % check to see if macros already loaded in (maybe some other file says
- % "\input psfig") ...
