This bug still applies. I don't know why "format=GTiff type=Byte
createopt=COMPRESS=JPEG" do not work together. The output raster is all
black. According to GeoTIFF spec JPEG compression should work just fine
with integer raster: "JPEG should only be used with Byte data" [1].

I thought that I had replied to this already.

Oh; I did, but none of the addresses in the original message accept
replies, so it went into the bit-bucket.
r.out.gdal creates paletted images (i.e. the map data is saved as a
single band; it isn't expanded to RGB).
Note that the argument to creatopt= is passed directly to GDAL.
r.out.gdal has no knowledge of which options are allowed or
meaningful, so it's up to the user not to pass options which won't work.

Too bad, yes.

single band; it isn't expanded to RGB).

I guess I comply.
In spearfish:
$ g.region rast=vegcover
$ r.out.gdal in=vegcover format=GTiff type=Byte
out=tmp/vegcover_jpg.tif createopt=COMPRESS=JPEG
Is there something wrong with: "format=GTiff type=Byte
createopt=COMPRESS=JPEG" when exporting an integer raster, value range 1-6:
In spearfish:
$ r.info -t vegcover
datatype=CELL
$ r.info -r vegcover
min=1
max=6
in the context of what GDAL's GeoTIFF spec says: "JPEG should only be
used with Byte data"?

r.out.gdal creates paletted images, to which JPEG compression cannot
be applied.
IOW, regardless of which other options you use,
createopt=COMPRESS=JPEG will always result in an error.

OK. Closing bug as invalid.
