Ramesh,
Instead of 'pasting' a part of your code, could you attach your entire .cpp
file along with the main() function and stuff?

Dear Sir,
Thanks a lot for reply about zero pixel values when I attempted to
write into an output image file. Though I pasted the code I wrote for
programmatically 'copying' the image, once again I am pasting the same
below.

Unfortunately I can’t provide the file (it’s about 2.1 GB and not releasable),
but below is the ‘gdalinfo’ dump for it.
The problem may be related to size of the input, because the same command
worked OK on a GeoTiff that is “only” 975 MB.
BTW For the 975 GB run that succeeded, the created ov
Jay,
Can you provide a sample file that gives this error?

Hello list,
(using GDAL 1.8.0) I am trying to create a 32:1 down-sampled overview of a
GeoTiff satellite image. My first thought was gdal_translate, with args such
as "-outsize 3.125% 3.125%"... which produces surprisingly high quality given
the absence of a resampling option. However I'm loo

With gdal_translate you can do per band re-scaling. I've used it on
Landsat, it's not magic but it works pretty well. You can group your
images, find the right formula for each group and you can quickly verify
the results with a VRT.

The Gimp? Blender can also provide this sort of functionality.

Hi Roland,
(lets cc the gdal list, so others can join in reading and/or answering)
If I recall correctly, you just have to make sure your input dataset is
rgba. I think I usually had a 4-channel 8-bit geotiff, tiled, and with
overviews (use gdaladdo to add them). I'm using a self-compiled very

firstly, whilst SQLPLUS is a useful tool to ensure the Oracle environment is
correctly configured, it does not test ODBC - nor does the very much nicer, Java

The creation of 0394w.tif failed. Does the process have write permission on

I note that you did not specify the -of option for nearblack. In it's
absence, nearblack creates the output file in Erdas Imagine format.
