Alters the resolution of the dataset and rebuilds the spatial indexes.
[Visual Basic .NET] Public Sub AlterResolution ( _ ByVal xyResolution As Double, _ ByVal zResolution As Double, _ ByVal mResolution As Double _ )
[C#] public void AlterResolution ( double xyResolution, double zResolution, double mResolution );
[C++]
HRESULT AlterResolution(
double xyResolution,
double zResolution,
double mResolution
);
[C++]
Parameters xyResolution [in] xyResolution is a parameter of type double zResolution [in] zResolution is a parameter of type double mResolution [in] mResolution is a parameter of type double
AlterResolution will change the resolution of the dataset based on the supplied XY, Z and M resolution values and rebuild the spatial indices. AlterResolution can only be used on Low Precision datasets within a 9.2 Geodatabase. To determine if AlterPrecision can be used on dataset, use the IControlPrecision2::IsHighPrecision property.
Use the IGeoDatasetSchemaEdit2::ConstructResolutions method to obtain the applicable levels of resolution for your data.
If a value of -1 is supplied for the xyResolution or zResolution arguments, the current resolution will be maintained. The current resolution of for a dataset can be obtained from its spatial reference using the ISpatialReferenceResolution interface.
Any of the following scenarios will result in an error:
