GeoReferencedRaster

public GeoReferencedRaster(java.lang.String imageFileLocation)
                    throws java.lang.Exception

Throws:

java.lang.Exception

Method Detail

fetchRaster

protected void fetchRaster()
                    throws java.lang.Exception

Basic fetchRasters retrieves a raster from a file. To get a raster from somewhere else, override this method in subclasses.

Throws:

java.lang.Exception

createJAIRenderedOP

protected void createJAIRenderedOP(java.net.URI uri)
                            throws java.io.IOException

Throws:

java.io.IOException

readRasterfile

protected void readRasterfile()
                       throws java.lang.Exception

Throws:

java.lang.Exception

normalize

protected void normalize(javax.media.jai.RenderedOp image)

This method must be overridden if an image is not a square image in modelspace. It should be transformed to make it a square image in modelspace.

Parameters:

image -

getCoorModel_tiepointLT

public com.vividsolutions.jts.geom.Coordinate getCoorModel_tiepointLT()

Returns:

coordinate of left-top corner in the model coordinate system

getCoorRasterTiff_tiepointLT

public com.vividsolutions.jts.geom.Coordinate getCoorRasterTiff_tiepointLT()

Returns:

coordinate of left-top corner in the raster coordinate system

getDblModelUnitsPerRasterUnit_X

public double getDblModelUnitsPerRasterUnit_X()

Returns:

number of model units per raster unit along X axis

getDblModelUnitsPerRasterUnit_Y

public double getDblModelUnitsPerRasterUnit_Y()

Returns:

number of model units per raster unit along Y axis

getImage

public javax.media.jai.RenderedOp getImage()
                                    throws java.lang.Exception

Throws:

java.lang.Exception
