DESCRIPTION
       This manual page documents ps2eps version 1.68.

       ps2eps is a tool (written in Perl) to produce Encapsulated PostScript
       Files (EPS/EPSF) from usual one-paged Postscript documents. It
       calculates correct Bounding Boxes for those EPS files and filters some
       special postscript command sequences that can produce erroneous results
       on printers. EPS files are often needed for including (scalable)
       graphics of high quality into TeX/LaTeX (or even Word) documents.

       Without any argument, ps2eps reads from standard input and writes to
       standard output. If filenames are given as arguments they are processed
       one by one and output files are written to filenames with extension
       .eps. If input filenames have the extension .ps or .prn, this extension
       is replaced with .eps. In all other cases .eps is appended to the input
       filename. Please note that PostScript files for input should contain
       only one single page (you can possibly use the psselect from the
       psutils package to extract a single page from a document that contains
       multiple pages).

       If BoundingBox in output seems to be wrong, please try options --size
       or --ignoreBB. See also section TROUBLESHOOTING.

OPTIONS
       ps2eps follows the usual GNU command line syntax, with long options
       starting with two dashes (`-'). A summary of options is included below.

       -h, --help
           Show summary of options.

       -V, --version
           Show version of program.

       -f, --force
           Force overwriting existing files.  ps2eps will not overwrite files
           by default to avoid deleting original EPS files accidently.

       -q, --quiet
           quiet operation (no output while processing files, except errors).

       -N, --noinsert
           do not insert any postscript code. Normally a few postscript
           instructions are added around the original postscript code by
           ps2eps which can be turned off by this option.

       -O, --preserveorientation
           do not filter %%Orientation: header comment.

       -n, --nofix
       -C, --clip
           insert postscript code for clipping. Unless --nohires is specified,
           the HiResBoundingBox (enlarged by 0.1 points) is used for clipping.

       -m, --mono
           use black/white bitmap as base for calculation (default: off).

       -s, --size=pagedim
           where pagedim is a pre-defined standard page size (e.g.,
           a4,a0,b0,letter,...) or explicitly specified in a format
           pagedim:=XxY[cm|in], where X and Y are numbers (floating points are
           accepted) followed by units centimeter (cm) or inch (in), (default:
           cm). Use --size=list to list pre-defined pagesizes. See also
           environment variable PS2EPS_SIZE.

       -t, --translate=x,y
           specify an x,y offset (may be negative) in postscript points (1/72
           dpi) for drawing. This option may be required if your drawing has
           negative coordinates which usually lets ghostscript cut the
           negative part of your picture, because it starts to render at
           positive coordinates. The resulting output will also be shifted.

       -r, --resolution=dpi
           specify a resolution in dpi (dots per inch) for drawing under
           ghostscript. Default resolution is 144 dpi which is the double of
           the typical 72 dpi. This option may help if there is a hardware
           dependent resolution encoded in the postscript, e.g., 600dpi.
           Example: ps2eps -l -r 600 test.ps

       -R, --rotate=direction
           This option rotates the resulting EPS output. The parameter
           direction determines the direction of rotation: + means +90 degrees
           (clockwise),- means -90 degrees (counter-clockwise), and ^ means
           180 degrees (up-side down).

       -l, --loose
           expand the original tight bounding box by one point in each
           direction.

       -B, --ignoreBB
           do not use existing bounding box as page size for rendering.

       -E, --ignoreEOF
           do not use %%EOF as hint for end of file. Otherwise, ps2eps assumes
           that postscript code ends after the last %%EOF comment, because
           some drivers add trailing binary "garbage" code which gets deleted
           by ps2eps by default.

       -g, --gsbbox
           use internal bbox device of ghostscript instead of the external C
           program bbox. The internal bbox device of ghostscript generates
           different values (sometimes even incorrect), so using the provided
           bbox should be more robust. See also environment variable
           PS2EPS_GSBBOX.
           show ghostscript call. This may be helpful for solving problems
           that occur during a ghostscript call.

       -W, --warnings
           show warnings about sanity of generated EPS file. Certain
           postscript commands should not be contained in an EPS file. With
           this option set ps2eps will issue a warning if it detects at least
           one of them.

TROUBLESHOOTING
       Based on the given postscript source code (in most cases generated by
       some postscript printer driver) there are many potential obstacles or
       problems that may occur when trying to create proper EPS files. Please
       read this section carefully to be aware of common pitfalls.

   Incomplete/Clipped Images
       or how to determine the right size for ghostscript.

       If you have documents that are larger than your ghostscript default
       (usually A4 or US letter), you have to specify the page dimensions
       explicitly using the -s option. Otherwise your EPS might be cut off
       during rasterizing by ghostscript resulting in a wrongly calculated
       bounding box. You can pass all pre-defined page sizes to -s that
       ghostscript understands. These are currently: 11x17, ledger, legal,
       letter, lettersmall, archA, archB, archC, archD, archE a0, a1, a2, a3,
       a4, a5, a6, a7, a8, a9, a10, isob0, isob1, isob2, isob3, isob4, isob5,
       isob6, b0, b1, b2, b3, b4, b5, c0, c1, c2, c3, c4, c5, c6, jisb0,
       jisb1, jisb2, jisb3, jisb4, jisb5, jisb6, flsa, flse, halfletter.
       Unfortunately, all sizes are currently only available in portrait
       orientation (not landscape).

       By default, ps2eps uses an already given %%BoundingBox from the source
       file, which often corresponds to the size of the physical page format
       for which the document was printed. However, you should be aware that
       this already specified bounding box may be not correct, thus resulting
       in a wrongly cropped (or even no usable) .eps-file.  ps2eps can only do
       as good as ghostscript does in rendering the original postscript file
       (though ps2eps even works with negative and fractional values are
       contained in the original bounding box by using automatic translation).
       Therefore, if the given bounding box is to small or incorrect anyway,
       you can ignore the existing bounding box with the -B option, which will
       cause ghostscript to use its internal default size (or use -s).
       However, if the BoundingBox has negative coordinates, which is not
       allowed by the specification, ps2eps will shift the output to positive
       values.

       Hint: to avoid rotating the picture if you have the original drawing in
       landscape format, you may use the "Encapsulated Postscript" option in
       the printer driver which should generate an EPS file (but with a
       bounding box of the sheet size!). But some Windows printer drivers are
       drawing the image with an offset from the bottom of the portrait page,
       so that a part of it is drawn outside the landscape oriented page. In
       this case, you'll have to specify a square size of the page using the
       maximum length, e.g., 29.7cm x 29.7cm for an A4 page.
       very badly behaving Postscript code (initclip) which will even override
       the outer clipping! Thus, a new filter had to be installed in ps2eps
       which will fix it.

       However, because most programs clip directly on the bounding box, you
       still may loose some pixels of your image, because the bounding box is
       described in the coarse resolution of postscript points, i.e. 72 dpi.
       In order to prevent this, you can use the -l option or -C option (for
       the latter, clipping by the importing program should be disabled then)
       to allow for a 1 point larger bounding box.  -C clips around a 1 point
       enlarged bounding box and -l enlarges the bounding box values by 1
       point (you can also combine both options).

   Included Filters
       Some postscript sequences, e.g., for using specific printer features
       (featurebegin ...), are not working well within an .eps file, so ps2eps
       tries to filter them out. But please note that filters for postscript
       code may not work properly for your printer driver (ps2eps was mainly
       tested with HP and Adobe printer drivers, although it may work for all
       printers using the PScript.dll). In this case you can try to turn of
       filtering by using option -n, or try to find the bad sequence in the
       postscript code and adapt the filter rule in the ps2eps script
       (variables $linefilter, $rangefilter_begin, $rangefilter_end;
       linefilter is an expression for filtering single lines, rangefilter_...
       are expressions that filter all lines between a pattern matching
       $rangefilter_begin and $rangefilter_end; drop me an e-mail with your
       modifications). However, things may change as the printer drivers
       (e.g., PScript.dll) or postscript language evolve.

       Some applications or drivers generate postscript code with leading or
       trailing binary code, which often confuses older postscript
       interpreters.  ps2eps tries to remove such code, but it may sometimes
       make a wrong guess about start and end of the real postscript code
       (drop me an e-mail with a zipped postscript source, see section BUGS).

       Comment lines or even blank lines are removed (which is the default to
       make .eps files smaller), which may corrupt your output. Please check
       the next section how to fix this.  ps2eps removes blank lines and also
       <CR> (carriage ceturn "\r") at the end of lines. However, nicely
       formatted postscript code gives a hint by using
       "%%BeginBinary""%%EndBinary" comments. When ps2eps detects these
       comments it will refrain from any filtering action within the marked
       binary sections.

       ps2eps filters also %%Orientation: comments by default (you can use
       option -O to turn off filtering), because ghostscript may
       "automagically" rotate images when generating PDF images, which is not
       desired in most cases. Hint: you can turn off that feature in
       ghostscript unconditionally by specifying -dAutoRotatePages=/None.

   Corrupted Output
       Some postscript code may get corrupted when comment lines or even blank
       lines are removed (which is the default to make .eps files smaller),
       because those files may contain encoded images which also have a % as
       may thus suppress objects drawn in light colors.

       Another option in case of memory problems and too long run times is to
       use the much more memory efficient internal ghostscript bbox by using
       the -g option.

ENVIRONMENT VARIABLES
       Please note that a command line option always takes precedence over the
       related environment variable.

       The environment variable PS2EPS_SIZE can be used to specify a default
       page size and take any argument that --size accepts. Examples: export
       PS2EPS_SIZE=a0 (bash-like syntax) or setenv PS2EPS_SIZE letter (csh
       syntax).

       If the environment variable PS2EPS_GSBBOX is set the internal bbox
       device of ghostscript will be used instead of the external command
       bbox. Examples: export PS2EPS_GSBBOX=true (bash-like syntax) or setenv
       PS2EPS_GSBBOX 1 (csh syntax).

EXAMPLES
       The usual call is simply: ps2eps -l file

       A relatively failsafe call would be (if your postscript is smaller than
       iso b0 [100cm x 141.4cm] and you have a fast computer with enough
       memory): ps2eps -l -B -s b0 -c -n file

       If output is not correct try: ps2eps -l -B -s b0 -F file

   WHY?
       Other programs like ps2epsi do not calculate the bounding box always
       correctly (because the values are put on the postscript stack which may
       get corrupted by bad postscript code) or rounded it off so that
       clipping the EPS cut off some part of the image.  ps2eps uses a double
       precision resolution of 144 dpi and appropriate rounding to get a
       proper bounding box. The internal bbox device of ghostscript generates
       different values (sometimes even incorrect), so using the provided bbox
       should be more robust. However, because normal clipping has only a
       resolution of 1/72dpi (postscript point), the clipping process may
       still erase parts of your EPS image. In this case please use the -l
       option to add an additional point of white space around the tight
       bounding box.
