public abstract class Callback_ThumbnailStore_getThumbnailByLongestSide
extends IceInternal.TwowayCallback
implements Ice.TwowayCallbackArg1UE<byte[]>
Retrieves a thumbnail for a pixels set using a given set of
 rendering settings (RenderingDef). If the thumbnail exists
 in the on-disk cache it will be returned directly, otherwise
 it will be created as in getThumbnailDirect,
 placed in the on-disk cache and returned. The longest side
 of the image will be used to calculate the size for the
 smaller side in order to keep the aspect ratio of the
 original image.
