I'm trying to use the following code to detect a possible error caused

does not raise an exception.
Making this call on the same dataset from native C code returns
CE_Failure from GDALGetGeoTransform().
Here's the C# snippet:
_dataset.GetGeoTransform(temp); // returns normally with default values
OSGeo.GDAL.CPLErr err = Gdal.GetLastErrorType();
if (OSGeo.GDAL.CPLErr.CE_None != err)
{
throw new ApplicationException("GetGeoTransform() failed.");
}
Am I doing anything wrong, or is it somehow a problem with the C#
bindings? I've built the C# bindings from the GDAL v1.5.3 release,
running on Win32.
Yonil,
There are some places in the GDAL code that return CE_Failure without
issuing an error via CPLError(). I presume you were expecting
GetLastErrorType() to return something other than CE_None if GetGeoTransform()
returned an error?
If you can provide details of the driver being used I may be able to correct
the code to issue a CPLError before returning CE_Failure but this is a
problem that is fairly widespread in the code.
PS. Doesn't the C# GetGeoTransform() method return the error indicator?
Best regards,
