Psfig/TeXfacilitates the inclusion of PostScript figures into TeXdocuments. To use psfig, the PostScript image must take advantage of the encapsulated postscript standard (eps). If your PostScript file has a line that starts with %%BoundingBox:, it can generally be assumed to follow this standard, and you should be able to use psfig without any problems.
The documentstyle must reflect the psfig macro style, so the following should be included in your documentstyle line:
\documentstyle[psfig]{article}
To include a figure named graph.ps, for example, simply include the following in your document.
\psfig{figure=rosette.ps}
The placement of the image should follow this line.
The manipulation of a PostScript image with psfig is also possible. To reduce a picture, for example, it is possible to include the following in your document.
\psfig{figure=graph.ps,height=4in,width=5in}
