setSubsetSize

public void setSubsetSize(int subsetSize)

Sets the grid subset size. If the EarthDataReader passed to create(noaa.coastwatch.io.EarthDataReader, java.lang.String) is capable of reading grid subsets via the GridSubsetReader interface, the specified grid subset dimension will be used to limit the total size of grid data read. The default subset size is set at 256, which is appropriate for previewing grid data.

Parameters:

subsetSize - the grid subset size.

create

public EarthDataView create(EarthDataReader reader,
 String varName)

Creates a new data view.

Parameters:

reader - the reader to use for variable data.

varName - the variable name to view.

Returns:

a new view of the data variable, or null on error.
