I don't know how to avoid the use of convert... I've found my way to produce georeferenced transparent images:
export the raster with r.out.png, create the pgw world file (extracting the values from r.info), and convert the outpu.png with "convert -transparent white output.png output_transp.png" I works fine for me. 2008/1/5, Moritz Lennert <[EMAIL PROTECTED]>: > On 05/01/08 02:23, David Finlayson wrote: > > Here is a link to my web site with the latest version: > > > > http://david.p.finlayson.googlepages.com/grasstogoogleearth > > > > I have something that works for me, but I was forced to use image > > magick to clip the nodata collar off of the exported png file.
