Hi, all: I'm having an error while using function Dataset.BuildOverviews in my code. The error message is "BuildOverviews() not supported for this dataset". However, when I used the ".tif" file the BuildOverviews worked just fine. The code is: int[] pOverviewList = { overView*2}; int[] pBandList = new int[dataset.RasterCount]; int err = dataset.BuildOverviews("NEAREST", pOverviewList); if (err != (int)CPLErr.CE_None) return null; I'm using GDAL1.5.2 and C#2.0. Is it because the HFA driver doesn't support overview? Or is it a bug? Can anyone pointed out where is my problem? Thanks a lot! -- Zhenyu Lu SUNY-ESF
