Are you using the current version of gs? I am using gswin32c 8.53 on Windows

What does "not so good" mean I just discovered the \startTEXpage \stopTEXpage to produce standalone PDF's for all my formulas. Then I took gswin32c to produce PNG's with gswin32c -dNOPAUSE -sDEVICE=png256 -sOutputFile=test.png test.pdf

Not so good means that in my first attempts the resolution of these png images were poor. Than I started using the -r300x300 and things got a bit better. Now I am trying to get all these images at a specific width x height so they show up correctly in my browser.

If you are still having problems, provide a minimal example (.tex source No problems, things work, here is an example of my Context source \starttext \startTEXpage \startformula e^{i x} = \cos x + i \sin x \stopformula \stopTEXpage \stoptext

my Context version is CtxTools | context version: 2007.04.17 12:51 (C:/Context/isoimage/usr/local/context/tex/texmf-local/tex/context/base/context.tex) CtxTools | context version: 2007.04.17 12:51 (C:/Context/isoimage/usr/local/context/tex/texmf-local/tex/context/base/cont-new.tex) Kind regards Wim
