Hi,
I have just started using the GDAL functions through the .NET wrapper
written by Tamas Szekeres.
I can get statistics on my GeoTIFF which is great, but I need to get the
count of pixels in each class in the raster.
Ideally I want to get the count by a range e.g. 123787
Even,
Thanks for the solution!

Juan,
GetFileList() is a relatively new feature in GDAL long history, so not all
drivers implement it : the default implementation just returns the name of the
main file passed to GDALOpen. I've just changed the FAST driver to return the
filenames of the bands. Done in trunk

As Chaintanya says and the doc recommands it, you must use the macro and not
string values directly. For one good reason : #define ODrCCreateDataSource
expands to "CreateDataSource"... So "ODrCCreateDataSource" is an invalid input
for OGRSFDriver::TestCapability(

Your reference to lanscoz is likely referring to Lanczos resampling
http://en.wikipedia.org/wiki/Lanczos_resampling
The gdalwarp man page shows that it supports 5 resampling methods:
near, bilinear, cubic, cubicspline, lanczos.

Hi,
I want to take a test about the capability of creation and deletion for all
supported formats of ogr .
The code like below, The parameter "const char" are copied from api doc. But
all flag return a value of 0, why ?
int flag;
flag=poDriver->TestCapability("ODrCCreateDataSource");

Hello,
I'm trying to use the GetFileList() function with a FAST-L7A image; it's
supposed to return a list with the files associated with the dataset, but it
only returns the administrative file (the _HRF.FST file). How can I get the
complete list o files?
Thanks

Viswanath,
RastorIO doesn't do any resampling. RasterIO doesn't have an argument like
hDstDS. I think the resampling is occuring during reprojection or some other
process.
