>This manual page documents <B

><P
><B
CLASS="COMMAND"
>ps2eps</B
> 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.
      It can also be used to calculate correct BoundingBoxes for PDF files by
      using the option <CODE
CLASS="OPTION"
>--BBonly</CODE
>. However, it cannot produce
      a PDF file, but it can be used together with <B
CLASS="COMMAND"
>pdfcrop</B
>.
    </P
><P
>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 <TT
CLASS="FILENAME"
>.eps</TT
>. If input filenames have the 
      extension <TT
CLASS="FILENAME"
>.ps</TT
> or <TT
CLASS="FILENAME"
>.prn</TT
>, this extension is replaced with <TT
CLASS="FILENAME"
>.eps</TT
>.
      In all other cases <TT
CLASS="FILENAME"
>.eps</TT
> is appended to the input filename.
      Please note that PostScript files for input should contain
      only one single page (you can possibly use the <B
CLASS="COMMAND"
>psselect</B
> from the
      psutils package to extract a single page from a document that
      contains multiple pages).</P

>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 
	<CODE
CLASS="OPTION"
>-s</CODE

	might be cut off during rasterizing by ghostscript resulting
	in a wrongly calculated bounding box. You can pass 
        all pre-defined page sizes to <CODE
CLASS="OPTION"

> 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,

><P
>	By default, <B
CLASS="COMMAND"

	wrongly cropped (or even no usable) <TT

	small or incorrect anyway, you can ignore the existing bounding box with the <CODE

	option, which will cause ghostscript to use its internal
	default size (or use <CODE

><P
>Hint: to avoid rotating the picture
	if you have the original drawing in landscape format, you may
	use the <SPAN
CLASS="QUOTE"
>"Encapsulated Postscript"</SPAN
> 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.</P

    which also have a % as first character in a line or use a special
    comment as end of image delimiter. If this is the case, use the <CODE

	the bitmap line by line so it consumes only minimal memory. If you experience problems
	with memory consumption of ghostscript, you may use the <CODE
CLASS="OPTION"

	for using a monochrome image. But this will probably result in wrongly
	determined bounding boxes with colored
	images, because ghostscript has to do black/white dithering and may thus suppress
	objects drawn in light colors.</P

>WHY?</H3
><P
>      Other programs like <B
CLASS="COMMAND"
>ps2epsi</B
> 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. <B
CLASS="COMMAND"
>ps2eps</B
> 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	<B
CLASS="COMMAND"
>bbox</B
>
	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 <CODE
CLASS="OPTION"
>-l</CODE
> option to add 
      an additional point of white space around the tight bounding box.
