    • 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
