+.TH EPSTOPDF 1 "7 January 2017"
+.\" $Id$
+.SH NAME
+epstopdf, repstopdf \- convert an EPS file to PDF
+.SH SYNOPSIS
+\fBepstopdf\fP [\fIoptions\fP] [\fIepsfile\fP [\fIpdffile\fP.pdf]]
+.SH DESCRIPTION
+By default, \fBepstopdf\fP converts the input PostScript file to PDF,
+using Ghostscript.
+.PP
+\fBEpstopdf\fP transforms the Encapsulated PostScript file \fIepsfile\fP
+(or standard input) so that it is guaranteed to start at the 0,0
+coordinate, and it sets a page size exactly corresponding to the
+BoundingBox.  Thus, the result needs no cropping, and the PDF MediaBox
+is correct.  
+.PP
+By default, the output name is the input name with any extension
+replaced by \fB.pdf\fP.  An output name ending with .pdf can also be given
+as a second argument on the command line, or the \fB--outfile\fP
+(\fB-o\fP) option can be used with any name.
+.PP
+PJL commands at the start of a file are removed.  DOS EPS binary files
+(TN 5002) are supported.
+.PP
+If the bounding box in the input is incorrect, of course there will
+be resulting problems.
+.SH OPTIONS
+Options may start with either "\fB-\fP" or "\fB--\fP", and may be
+unambiguously abbreviated.  It is best to use the full option name in
+scripts to avoid possible collisions with new options in the future.
+.PP
+General script options:
+.IP "\fB--help\fP
+display help message and exit
+.IP "\fB--version\fP
+display version information and exit
+.IP "\fB--outfile\fP=\fIfile\fP"
+write result to \fIfile\fP.  If this option is not given, and
+\fB--nogs\fP or \fB--filter\fP is specified, write to standard output;
+otherwise, the default is to construct the output file name by replacing
+any extension in the input file with `.pdf'.
+.IP "\fB--\fP[\fBno\fP]\fBdebug\fP"
+write debugging info (default: false).
+.IP "\fB--\fP[\fBno\fP]\fBexact\fP"
+scan ExactBoundingBox (default: false).
+.IP "\fB--\fP[\fBno\fP]\fBfilter\fP"
+read standard input and (unless \fB--outfile\fP is given) write standard
+output (default: false).
+.IP "\fB--\fP[\fBno\fP]\fBgs\fP"
+run Ghostscript (default: true).  With \fB--nogs\fP, output (to standard
+output by default) the PostScript that would normally be converted; that
+is, the input PostScript as modified by \fBepstopdf\fP.
+.IP "\fB--\fP[\fBno\fP]\fBhires\fP"
+scan HiresBoundingBox (default: false).
+.IP "\fB--restricted\fP=\fIval\fP"
+turn on restricted mode (default: [true for repstopdf, else false]);
+this forbids the use of \fB--gscmd\fP and other options and imposes
+restrictions on the input and output file names according to the values
+of openin_any and openout_any (see the Web2c manual, http://tug.org/web2c).
+.PP
+Options for Ghostscript (more info below):
+.IP "\fB--gscmd\fP=\fIval\fP"
+pipe output to \fIval\fP (default: [\fBgswin32c\fP on Windows, else \fBgs\fP])
+.IP "\fB--gsopt\fP=\fIval\fP"
+include \fIval\fP as one argument in the gs command (can be repeated).
+.IP "\fB--gsopts\fP=\fIval\fP"
+split \fIval\fP at whitespace and include each resulting word as an
+argument in the gs command (can be repeated).
+.IP "\fB--autorotate\fP=\fIval\fP"
+set AutoRotatePages (default: None); recognized \fIval\fP choices:
+None, All, PageByPage.  For EPS files, PageByPage is equivalent to All.
+.IP "\fB--\fP[\fBno\fP]\fBcompress\fP"
+use compression in the output (default: true); if turned off, passes
+.IR -dUseFlateCompression=false .
+.IP "\fB--device\fP=\fIdev\fP"
+use -sDEVICE=\fIdev\fP (default: pdfwrite); not allowed in restricted mode.
+.IP "\fB--\fP[\fBno\fP]\fBembed\fP"
+embed fonts (default: true); passes
+.I -dMaxSubsetPct=100 -dSubsetFonts=true -dEmbedAllFonts=true.
+.IP "\fB--\fP[\fBno\fP]\fBgray\fP"
+grayscale output (default: false); passes
+.I -sColorConversionStrategy=Gray -dProcessColorModel=/DeviceGray.
+.IP "\fB--pdfsettings\fP=\fIval\fP"
+use -dPDFSETTINGS=/\fIval\fP (default is `prepress' if \fB--embed\fP,
+else empty); recognized \fIval\fP choices: screen, ebook, printer,
+prepress, default.
+.IP "\fB--\fP[\fBno\fP]\fBquiet\fP"
+use -q, a.k.a. -dQUIET (default: false).
+.IP "\fB--res\fP=\fIdpi, dpi\fPx\fIdpi\fP"
+set image resolution (default: [use gs default]); ignored if
+\fB--debug\fP is set.
+.IP "\fB--\fP[\fBno\fP]\fBsafer\fP"
+use -d(NO)QUIET (default: true).
+.PP
+In addition to the specific options above, additional options to be used
+with gs can be specified with either or both of the two cumulative
+options \fB--gsopts\fP and \fB--gsopt.\fP
+.PP
+\fB--gsopts\fP takes a single string of options, which is split at
+whitespace, each resulting word then added to the gs command line
+individually.
+.PP
+\fB--gsopt\fP adds its argument as a single option to the gs command
+line.  It can be used multiple times to specify options separately,
+and is necessary if an option or its value contains whitespace.
+.PP
+In restricted mode, options are limited to those with names and values
+known to be safe.  Some options taking booleans, integers or fixed
+names are allowed, those taking general strings are not.
+
+.SH EXAMPLES
+These examples all equivalently convert `test.eps' to `test.pdf':
+.nf
+epstopdf test.eps
+epstopdf test.eps test.pdf
+cat test.eps | epstopdf --filter >test.pdf
+cat test.eps | epstopdf -f -o=test.pdf
+.fi
+.PP
+Example for using HiResBoundingBox instead of BoundingBox:
+.nf
+epstopdf --hires test.eps
+.fi
+.PP
+Example for \fBepstopdf\fP's attempt at correcting PostScript:
+.nf
+$program --nogs test.ps >testcorr.ps
+.fi
+.PP
+In all cases, you can add \fB--debug\fP (\fB-d\fP) to see more about
+what \fBepstopdf\fP is doing.
+.SH BUGS
+The case of "%%BoundingBox: (atend)" when input is not seekable (e.g.,
+from a pipe) is not supported.
+.PP
+Report bugs in the program or this man page to tex-k@tug.org.  When
+reporting bugs, please include an input file and the command line
+options specified, so the problem can be reproduced.
