Method Detail

isEnabledMultiresolution

boolean isEnabledMultiresolution()

Returns true if the multiresolution is enabled

Returns:

getZoomLevel

int getZoomLevel()

Gets the current zoom level

Returns:

setZoomLevel

void setZoomLevel(int zoomLevel)

Sets the current zoom level

Parameters:

zoomLevel -

increaseZoomLevel

boolean increaseZoomLevel()

Increase the current zoom level

decreaseZoomLevel

boolean decreaseZoomLevel()

Decrease the current zoom level

getCoordsInLevel

Envelope getCoordsInLevel(Point2D center,
                          int level,
                          int w,
                          int h)
                   throws CreateEnvelopeException

Calculates the bounding box of a zoom level using a center defined in pixels. It's possible to define the center in pixels because a level of resolution has a pixel size.

Parameters:

center - center in world coordinates

level - level of resolution

w - width in pixels

h - height in pixels

Returns:

Throws:

CreateEnvelopeException

setTileServer

void setTileServer(Class<?> tileServer)
            throws InitializeException

Sets a tile server to create a second level of cache. This second level will be created if the cache structure is different to the current.

Parameters:

tileServer -

Throws:

InitializeException
