Method Detail

isDataEditable

public boolean isDataEditable()
Returns true if grid data can be edited.

Specified by:
isDataEditable in interface GridCoverage
Returns:
true if grid data can be edited.

getGridGeometry

public GridGeometry getGridGeometry()
Information for the grid coverage geometry. Grid geometry includes the valid range of grid coordinates and the georeferencing.

Specified by:
getGridGeometry in interface GridCoverage
Returns:
the information for the grid coverage geometry.

getAsImage

public abstract java.awt.image.BufferedImage getAsImage(int xAxis,
                                                        int yAxis)
this is a deegree convenience method which returns the source image of an ImageGridCoverage. In procipal the same can be done with the getRenderableImage(int xAxis, int yAxis) method. but creating a RenderableImage image is very slow.

Parameters:
xAxis - Dimension to use for the x axis.
yAxis - Dimension to use for the y axis.
Returns:
the image

paintImage

protected java.awt.image.BufferedImage paintImage(java.awt.image.BufferedImage targetImg,
                                                  Envelope targetEnv,
                                                  java.awt.image.BufferedImage sourceImg,
                                                  Envelope sourceEnv)

paintImage

protected java.awt.image.BufferedImage paintImage(java.awt.image.BufferedImage targetImg,
                                                  float[][] data,
                                                  Envelope targetEnv,
                                                  java.awt.image.BufferedImage sourceImg,
                                                  Envelope sourceEnv)
renders a source image onto the correct position of a target image according to threir geographic extends (Envelopes).

Parameters:
targetImg -
targetEnv -
sourceImg -
