Method Detail

drawOnTo

void drawOnTo(DataRaster canvas)

Copies this raster into a specified raster.

Parameters:

canvas - - the raster to copy into.

getHeight

int getHeight()

Returns the raster's height in raster units.

Returns:

the raster's height in raster units.

getSector

Sector getSector()

Returns the region covered be the data.

Returns:

a sector indicating the region covered by the raster.

getSubRaster

DataRaster getSubRaster(AVList params)

Returns a portion of this raster as another raster. Input values are the desired width and height of the return sub-raster, and the sector to copy from this raster to the sub-raster. The returned raster conforms to EPSG:4326 even if this raster does not.

Parameters:

params - a list of parameters that specify the width, height and sector of the region to return. Specify these values using AVKey.WIDTH, AVKey.HEIGHT and AVKey.SECTOR.

Returns:

the requested raster, or null if the raster could not be created.

Throws:

IllegalArgumentException - if the specified parameter list is missing the width, height or sector keys or any of those values are invalid.

getSubRaster

DataRaster getSubRaster(int width,
                        int height,
                        Sector sector,
                        AVList params)

Returns a portion of this raster as another raster. The returned raster conforms to EPSG:4326 even if this raster does not.

Parameters:

width - the width to make the returned sub-raster.

height - the height to make the returned sub-raster.

sector - the sector to copy.

params - a list of parameters that specify the width, height and sector of the region to return. Specify these values using AVKey.WIDTH, AVKey.HEIGHT and AVKey.SECTOR.

Returns:

the requested raster, or null if the raster could not be created.

Throws:

IllegalArgumentException - if the sector is null or the width, height or sector are invalid.

getWidth

int getWidth()

Returns the raster's width in raster units.

Returns:

the raster's width in raster units.
