Hello all,
Is there a way to get the 1.6 version of gdal2tiles to clamp tiles to the
seafloor? I've tried modifying the script with &

approach?

Special thanks Even. You are always quick and to the point! Thank you very
much.
As you pointed out, I was handling JPEG in the same manner as GTiff; I did not
use the MEM driver first.
With best regards.

Use:
if (!pDriver->TestCapability(ODrCCreateDataSource))
to test create capabilties of the driver.
I think jpeg driver only supports CreateCopy().
You could use the Memory dataset to create a different size dataset and then
use the jpeg driver to save it to disk.

When I try to use GDALCreate() on the JPEG driver, I got the following error:
"GDALDriver::Create() ... no create method implemented for this format."
Does is this mean that JPEG driver does not have its GDALCreate() function
implemented? Any example on how to use JPEG driver is

Frank,
I suppose you are asking for the GDAL driver.
However, just to confirm, gdal2wktraster can generate
WKT Raster datasets with overviews (in regular blocking mode).
