Equations saved as gif, but file ending png

Doxygen 1.6.1 openSUSE 11.0 x64
When formulas are in dox/html created they have the file ending png, but the contents is in fact gif. This must be a bug? Anybody else seen this problem? How is Doxygen creating the images? latex->dvips then what? convert, or something else? I cannot find any switches or settings in the Doxygen file. -Ole Jacob ------------------------------------------------------------------------------ Come build with us!

Hi,
This is a known bug indeed, see https://bugzilla.gnome.org/show_bug.cgi?id=595253 It has already been fixed in subversion. For formulas the chain is now: - doxygen (.tex) - latex (.tex->.dvi) - dvips (.dvi->.eps) - doxygen (.eps->.ps) - ghostscript (.ps->.pnm) - doxygen (.pnm->.gif) Doxygen used to generate PNGs but I got a bit tired of the bugs that were found in libpng, so in release 1.6.0 I switched back to the simple gif encoder I had used 8 years ago (I previously switched to PNG due to patent issues, but the GIF patent has expired in the meantime).

Hi,
In the latest svn checkin equations for html output are now created as gifs with the gif suffix, but the html files contains references to pngs, and no gifs.
