F. Beebe <beebe@math.utah.edu> + +============ +Introduction +============ + +The epsf.tex and epsf.sty (identical) files provide for +low-level typesetting of Encapsulated PostScript (EPS) +files, with optional suppression of the figure contents (for +faster display and printing during document development), +optional figure framing, and optional figure labeling. + +See the header comments in epsf.tex or epsf.sty files for +usage information. + +LaTeX users are cautioned that the graphicx package +documented in the LaTeX Graphics Companion and LaTeX +Companion (2nd ed.) books provides a much more powerful and +general facility, and allows easy switching between +pdf(la)tex and (la)tex without document modification. + +Plain TeX and AmSTeX users, however, may find epsf.tex +useful. + + +=================== +Testing the package +=================== + +The test files in the package can be typeset on Unix systems +with + + make check + +You can then view or print the .dvi files to see several +examples of what they are supposed to look like. + +If you are in doubt about their appearance when generated at +your site, try the okay/*.dvi files: they were produced by +the package maintainers to illustrate the correct behavior +the package macros. + + +================= +Problem EPS files +================= + +If you experience difficulty in positioning an EPS picture, +and find that it appears in an unexpected location, or in an +incorrect scale or orientation, then it is often the case +that the PostScript is not EPSF-conformant (see the +specification in the references below). This may be because +it uses forbidden low-level PostScript operators that modify +the PostScript page transformations. The fndbadps shell +script in the distribution can be used on Unix systems to +search for forbidden operators in EPS files. If you find +any, you should complain to the author or vendor of the +software that produced the bad EPS files: the EPS +specification has been available since 1992, and is very +clear about what operators are forbidden. + +It is sometimes possible to repair problem EPS files by +converting from PostScript to PDF and back to PostScript. +Suitable tools for PostScript to PDF conversion include +Adobe distill, ghostscript ps2pdf, and Frank M. Siegert's +pstill. For PDF to PostScript conversion, use Adobe +acroread, ghostscript pdf2ps, or your PDF file viewer's +print-to-PostScript-file option. + +In bad cases, the only way to deal with a problem EPS file +may be to convert it to a high-resolution bitmap and back to +PostScript, taking care to choose a lossless bitmap format. +This can be done with the NetPBM tools and ghostscript. +These utilities offer a myriad of options, so it is +convenient to combine them in a separate tool that provides +the commonly-needed options: pstopngtops (see the References +section below). + + +=========================== +Bounding boxes and clipping +=========================== + +Sometimes the only problem is that the size of the figure is +wrong. This is usually because the %%BoundingBox comment +that is normally present in the first few lines of the EPS +file is wrong: indeed, most PostScript-producing software +produces nonsensical bounding boxes. + +One way to fix this problem is to print your EPS file and +the bboxgrid.ps file from this package on the SAME printer, +overlay them against a light source, and measure the +lower-left and upper-right corner coordinates in big points +(72bp = 1in = 25.4mm) of the picture and then edit the EPS +file to supply the correct coordinates as whole numbers in +order: + + %%BoundingBox: lower-left-x lower-left-y upper-right-x upper-right-y + +The PostScript coordinate system is right-handed Cartesian +with the origin at the lower-left page corner. The reason +that you need the grid provided by bboxgrid.ps is that even +though PostScript defines the coordinate position (0,0) to +be at the lower-left page corner, mechanical limitations +and/or misadjustments in PostScript printers often result in +that point being displaced by as much 1cm in any direction. +Even two identical models of the same printer can differ in +their true page origins! When you measure the picture +corners of your figure using the bboxgrid.ps output on the +same printer, you eliminate this source of confusion and +error. + +A better way to obtain an accurate bounding box is to ask +ghostscript to measure it for you: + + % gs -sDEVICE=bbox -dNOPAUSE bboxgrid.ps quit.ps + AFPL Ghostscript 8.51 (2005-04-18) + Copyright (C) 2005 artofcode LLC, Benicia, CA.

TeX has to read the +EPS file until it finds the %%BoundingBox comment, and the +further it is from the beginning, the longer TeX will take +to find it.
