RemoteImageLoader

public RemoteImageLoader(String baseUrl)
                  throws IOException

Throws:

IOException

Method Detail

getSetupImgLoader

public RemoteImageLoader.SetupImgLoader getSetupImgLoader(int setupId)

Specified by:

getSetupImgLoader in interface mpicbg.spim.data.generic.sequence.BasicImgLoader

Specified by:

getSetupImgLoader in interface mpicbg.spim.data.generic.sequence.BasicMultiResolutionImgLoader

Specified by:

getSetupImgLoader in interface ViewerImgLoader

getCacheControl

public VolatileGlobalCellCache getCacheControl()

Specified by:

getCacheControl in interface ViewerImgLoader

getMipmapInfo

public MipmapInfo getMipmapInfo(int setupId)

existsImageData

public boolean existsImageData(ViewLevelId id)

Checks whether the given image data is present on the server.

Returns:

true, if the given image data is present.

getMissingDataImage

protected <T> net.imglib2.RandomAccessibleInterval<T> getMissingDataImage(ViewLevelId id,
                                                                          T constant)

For images that are missing in the hdf5, a constant image is created. If the dimension of the missing image is known (see getDimsAndExistence(ViewLevelId)) then use that. Otherwise create a 1x1x1 image.

getDimsAndExistence

public DimsAndExistence getDimsAndExistence(ViewLevelId id)

prepareCachedImage

protected <T extends net.imglib2.type.NativeType<T>> net.imglib2.RandomAccessibleInterval<T> prepareCachedImage(ViewLevelId id,
                                                                                                                net.imglib2.cache.volatiles.LoadingStrategy loadingStrategy,
                                                                                                                T type)

Create a VolatileCachedCellImg backed by the cache. The type should be either UnsignedShortType and VolatileUnsignedShortType.
