Method Detail

create

public static ColoredBandImageMultiLevelSource create(RasterDataNode rasterDataNode,
                                                      ProgressMonitor pm)

create

public static ColoredBandImageMultiLevelSource create(RasterDataNode[] rasterDataNodes,
                                                      ProgressMonitor pm)

create

public static ColoredBandImageMultiLevelSource create(RasterDataNode[] rasterDataNodes,
                                                      MultiLevelModel model,
                                                      ProgressMonitor pm)

setImageInfo

public void setImageInfo(ImageInfo imageInfo)

getImageInfo

public ImageInfo getImageInfo()

getImageShape

public Shape getImageShape(int level)

Description copied from interface: MultiLevelSource

Gets the shape of the area where this image's raster data contains valid pixels at the given resolution level. The method returns null, if the entire image raster contains valid pixels.

Specified by:

getImageShape in interface MultiLevelSource

Overrides:

getImageShape in class AbstractMultiLevelSource

Parameters:

level - The resolution level.

Returns:

The shape of the area where the image has data, can be null.

createImage

public RenderedImage createImage(int level)

Description copied from class: AbstractMultiLevelSource

Called by AbstractMultiLevelSource.getImage(int) if a level image is requested for the first time. Note that images created via this method will be disposed when AbstractMultiLevelSource.reset() is called on this multi-level image source. See AbstractMultiLevelSource.getImage(int).

The dimension of the level image created must be the same as that obtained from {DefaultMultiLevelSource.getLevelImageBounds(Rectangle sourceBounds, double scale)} for the scale associated with the given resolution level.

Specified by:

createImage in class AbstractMultiLevelSource

Parameters:

level - The resolution level.

Returns:

An instance of a RenderedImage for the given resolution level.
