Method Summary

static RasterMap	readRaster(String fileName, int fileFormat, GISFrame gisFrame, LSThread lsThread) Reads a text file in the given format and creates a raster map from it.
static boolean	writeRaster(RasterMap rasterMap, String fileName, int fileFormat, GISFrame gisFrame, LSThread lsThread) Writes a text file in the given format based on the supplied raster map.

Method Detail

readRaster

public static RasterMap readRaster(String fileName,
                                   int fileFormat,
                                   GISFrame gisFrame,
                                   LSThread lsThread)

Reads a text file in the given format and creates a raster map from it.

Parameters:

fileName - Name of file to read.

fileFormat - Type of text file to read (see FileHandler).

gisFrame - GUI in which to report results.

lsThread - Thread that called this method (allows it to be interrupted). Can be null, in which case, method cannot be interrupted.

Returns:

Raster map containing read data, or null if problems reading.

writeRaster

public static boolean writeRaster(RasterMap rasterMap,
                                  String fileName,
                                  int fileFormat,
                                  GISFrame gisFrame,
                                  LSThread lsThread)

Writes a text file in the given format based on the supplied raster map.

Parameters:

rasterMap - Raster map to write.

fileName - Name of file to create.

fileFormat - Type of text file to create (see FileHandler).

gisFrame - GUI in which to report results.

lsThread - Thread that called this method (allowing it to be interrupted). Can be null, in which case methdo cannot be interrupted.

Returns:

True if written sucessfully.
