Christiaan,
I have removed this inaccurate comment.
Also, am I wrong in thinking
the command "gdaladdo -ro test.img 2 4 8" should have at least generated an
.aux (or .rrd) file and not errored the way it did? Thanks.
The error message was unhelpful, but I presume the issue is that overviews
cannot be generated in a read-only file. If you would like to file a ticket
on this, I could look into more appropriate error handling.
I would add, if you wanted ovr support it should be relatively trivial for
you to add it in your local build with a call to initialize the
overview manager at the end of the Open() method.
poDS->oOvManager.Initialize( poDS, poOpenInfo->pszFilename );
I am hesitant to do this in the mainline code though.
Best regards,
