Class ImageSizePrereader

Object

ImageSizePrereader

public class ImageSizePrereader
extends Object

Reads the size of each image initially, before normal (parallel) task execution.

It first attempts to do this through a imageMetadataReader as often this is much faster than opening the stack with StackReader.
