[NTG-context] Convert eps to pdf
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.

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. -- Siep Kroonenberg ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
