Description
Although I specify 300 DPI in map composer, after exporting the map to PNG the declared DPI is not preserved. I have to set it manually eg. in GIMP.

Seems to me that this has been fixed. See the screenshot. Qgis 1.2 from trunk under Ubuntu 9.04
Please try again and leave feedback.

Seems that the problem has been solved, closing, but reopen if necessary.
Note:
See TracTickets
for help on using tickets.
Qgis uses a Qt library to write png's, and that library doesn't support embedding a DPI value into the png file. I note that gimp can embed such a value, so there may well be a formal or informal way to do it, but it's unlikely that we'll get around to doing that soon. None of the many other image viewers or editors that I viewed such a png with picked up the dpi set by gimp.
I'll move this to an enhancement against 0.9
