Method Detail

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:

java.net.URISyntaxException

java.io.IOException

ReferencedImageException

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 -
