#914: Add multi-channel "import" to r.external (as in r.in.gdal)
-------------------------+--------------------------------------------------
Reporter: neteler | Owner: grass-dev@lists.osgeo.org

Priority: normal | Milestone: 6.5.0
Component: Raster | Version: svn-trunk
Keywords: | Platform: All
      Cpu: All |
-------------------------+--------------------------------------------------
Currently, r.external "imports" only the first channel, not all
available channels as r.in.gdal does:

{{{
r.in.gdal 014_03.jpg out=mymap -o
WARNING: Over-riding projection check
  100%
r.in.gdal complete. Raster map <dd.red> created.
  100%
r.in.gdal complete. Raster map <dd.green> created.
  100%
r.in.gdal complete. Raster map <dd.blue> created.
}}}

The behaviour of r.in.gdal is more user-friendly, could r.external be
improved?

thanks,
Markus

As always, it works out of the box :slight_smile: Also tested with appropriate
modifications in 6.4.
