                                                             throws Exception

Get the GridCoverage2D in a certain region.

It might be usefull for faster access to the underlying data to extract the raster before creatin the iterator, instead of iterating directly.

This can be done on the returned gridcoverage through: Raster readRaster = readGC.getRenderedImage().getData(); RandomIter readIter = RandomIterFactory.create(readRaster, null);

Parameters:

readerNum - the number of the reader to use.

north -

south -

east -

west -

Returns:

the gridcoverage inside the supplied bounds.

Throws:

Exception

                                    int writeRows)

Process one cell.

This is used when processByTileCells() is called.

Parameters:

readCol - the column of the cell to read.

readRow - the row of the cell to read.

writeCol - the column of the cell to write.

writeRow - the row of the cell to write.

readCols - the total columns of the current handled read tile.

readRows - the total rows of the current handled read tile.

writeCols - the total columns of the current handled written tile.

writeRows - the total rows of the current handled written tile.
