Convert eps to pdf

Convert eps to pdf

[Alan BRASLAU]

ConTeXt mkiv will take an encapsulated postscript (eps) file through
\externalfigure [myfigure.eps]
and creates a (compressed) pdf version as m_k_i_v_myfigure.pdf
that conserves the vectorial components of the eps file.

Other standard conversion tools, notably those based on ghostscript,
generally create a bitmap image with pretty horrible results.

The vectorial conversion must be fully trivial, but I am ignorant
of the tools available for this manipulation (other than ConTeXt!),
as well as the inverse (pdf->eps) conversion. Perhaps I am simply
missing some simple (ghostscript, pstoedit, ...) option.

I am posting this question to the ConTeXt mailing list
as I am sure that someone can give a trivial answer,
but also to indicate to those who may ignore this robust
feature of ConTeXt.

Also, \externalfigure is a very powerful macro that would justify
more complete documentation in the revised reference manual.

1.) ps2pdf -dEPSCrop file.eps file.pdf

On some systems you have "epstopdf".

2.) gs -dSAFER -dBATCH -dNOPAUSE -dEPSCrop \
    -sDEVICE=pdfwrite -sOutputFile=file.pdf file.ps

I use the same command for conversion into bitmap figures:
    gs -dSAFER -dBATCH -dNOPAUSE -dEPSCrop \
    -dGraphicsAlphaBits=4 -dTextAlphaBits=4 -r500 \
    -sDEVICE=pngalpha -sOutputFile=file.png file.ps

Usually the conversion from PDF to EPS is slightly problematic for (to
me) unknow reason.

For pdf to eps, use pdftops from the xpdf suite
(http://www.foolabs.com/xpdf/). 

I wrote a Ruby script epspdf with a gui Tcl/Tk wrapper epspdftk
(http://tex.aanhet.net/epspdf/) for arbitrary conversions between
eps, ps and pdf in any direction, with optional cropping and
grayscaling. Epspdf and epspdftk are included in TeX Live.
