Methods for raster data stores with resolution levels

Method Summary

Modifier and Type	Method and Description
Extent	getCoordsInLevel(Point2D viewCenter, int level, int w, int h) Calculates the extent of a zoom level using a center.
Extent	getCoordsInTheNearestLevel(Extent extent, int w, int h) Calculates the extent of a zoom level using other extent as a reference.
int	getNearestLevel(double pixelSize) Gets the nearest level
int	getZoomLevels() Gets the number of zoom levels

Method Detail

getCoordsInTheNearestLevel

Extent getCoordsInTheNearestLevel(Extent extent,
                                  int w,
                                  int h)

Calculates the extent of a zoom level using other extent as a reference. This function is useful when the request is between two levels. It will adjust the request to the nearest zoom level.

Parameters:

level -

extent -

w -

h -

Returns:

getCoordsInLevel

Extent getCoordsInLevel(Point2D viewCenter,
                        int level,
                        int w,
                        int h)

Calculates the extent of a zoom level using a center.

Parameters:

viewCenter -

level -

w -

h -

Returns:

getZoomLevels

int getZoomLevels()

Gets the number of zoom levels

Returns:

getNearestLevel

int getNearestLevel(double pixelSize)

Gets the nearest level

Parameters:

pixelSize -

Returns:
