Constructor Detail

GeoRaster

public GeoRaster(String imageFileLocation)

GeoRaster

public GeoRaster(String imageFileLocation,
                 Object fixed_reader)

Method Detail

getURI

protected URI getURI()

fetchRaster

protected void fetchRaster()
                    throws ReferencedImageException

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

Throws:

ReferencedImageException - if an Exception occurs in File#canRead, in createJAIRenderedOP or if no reader wants to decode the Raster

readRasterfile

protected void readRasterfile()
                       throws ReferencedImageException

Throws:

ReferencedImageException

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 - image to be normalized (squared)

getImage

@Deprecated
public javax.media.jai.RenderedOp getImage()
                                    throws ReferencedImageException

Deprecated.

Throws:

ReferencedImageException

getRenderedOp

public javax.media.jai.RenderedOp getRenderedOp()
                                         throws ReferencedImageException

Throws:

ReferencedImageException

fullContrast

public javax.media.jai.RenderedOp fullContrast()

getMinimumExtreme

public double[] getMinimumExtreme()

getMaximumExtreme

public double[] getMaximumExtreme()

getType

protected String getType()

getLoader
