Hi,
r.out.tiff has a -t flag to create a world file.
r.out.png has a -t flag to make NULL cells transparent.
it would be really useful if they both could have both flags. For use with
gdal2tiles.py + OpenLayers you need both but only can get one or the
other! Probably it is some pretty easy cutting and pasting of code
between the two modules.

Comment (by glynn):
Replying to [comment:2 hamish]:
> does TIFF support transparency?
Yes.
More importantly, transparency is supported by most applications which
read TIFF files. What information can be stored in a TIFF file is often
less important than what information programs which "support TIFF"
understand (e.g. the problems with 16-bit paletted images).
