[gdal-dev] using GDALCreateCopy and changing only the datatype

[Yann Chemin]

Hi Sjur,

I found out that in:
hDatasetOut0 = GDALCreateCopy( hDriver1, ndviF, hDataset1,FALSE,NULL,NULL,NULL);

the FALSE argument was there to inhibit strict identity to the parent
dataset it copies. However, when trying to induce it to write in
GDT_Float64 instead of int32, it brings out the file as int32....

so far for allowing change...
