How can I convert a .jpg image to an .eps?
7 Answers
ImageMagick can do this.
From the commandline, simply type:
convert filename.jpg filename.eps
(On Windows you may need to put in the full path to convert.exe inside quotation marks; the above will work as-is on OS X or linux.)
It doesn't really make any sense to convert a raster graphic to a vector graphic, however. It'll still be rasterized.
Another way of doing it with a GUI would be to use Inkscape; I'm pretty sure it can import most formats, and it definitely can export to .eps — it does have some ways of trying to trace paths in a vector image to recreate the vectors, but it's far from failsafe.
Just be sure to "embed" rather than "link" when you import.
If you just want to convert an image or two to eps - use an online utility...
The best solution I know for something that runs locally, is lossless, and performs well is to take the output of img2pdf and feed it to pdftops from Poppler (poppler-utils on Debian-family distros).
img2pdf is specifically designed for converting one or more images into a one-image-per-page PDF file in a lossless fashion (ImageMagick and Ghostscript will decode and re-encode JPEGs, which is lossy) and, since both formats are Postscript-based, it shouldn't need to be re-transcoded in the move from PDF to EPS.
The conversion would looks like like:
img2pdf --out filename.pdf filename.jpg
pdftops -f 1 -l 1 -eps filename.pdf filename.eps
rm filename.pdf
The -f 1 and -l 1 specify the first and last page to convert, and are both required to be 1 when using -eps.

If you just want the jpeg image contained in the .eps file (and not vectorized), try this code
http://code.google.com/p/sam2p/
It's C++ source, and takes several image formats and puts them inside a compliant .eps file as an embedded image.

if the question involves postscript the answer is generally ghostscript / ghostview
