Hi David,
So, is there any ConTeXt equivalent to LaTeX's \psfrag command?
No.
It would be very useful to process PostScript output from vector graphics drawing programs.
How does psfrag from LaTeX work internally? Perhaps we are able to make something similar.
I don't know how about its internals, but here's a usage example. For instance, using some vector graphics program, I write a text label "alpha" on some figure, and I print this figure in an EPS file. Then, using PSfrag, right before \including the EPS file, I tell PSfrag to replace "alpha" with "$\alpha $": \psfrag{alpha}{$\alpha$} \includegraphics{some_eps_file} I believe PSfrag works in conjunction with dvips. There's this PS file which may give you some clue: texmf/dvips/psfrag/psfrag.pro I can neither read TeX code nor PS code, but it is likely that it builds some sort of lookup table for the labels. If I can help anyway, please tell me. There are those two other files: texmf/tex/plain/graphics/psfrag.tex texmf/tex/latex/misc/psfrag.sty David
