% ======================================================================
|
|
% 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.
|
|
%
|
|
% ======================================================================
|
|
%
|
|
% 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.
|
|
%
|
|
% ======================================================================
