Been tearing my hair on this one.
How do I split a multipage / multilayer TIFF image into several individual images?
Demo image available here.
(Would prefer a pure Java (i.e. non-native) solution. Doesn't matter if the solution relies on commercial libraries.)

❓ How can I split TIFF document? First, you need to add a file for split: drag & drop your TIFF file or click inside the white area for choose a file. Then click the 'Split' button. When split TIFF document is completed, you can download your result files.
Hit CTRL + P, or navigate to the printing dialog by clicking File > Print… From the list of available printers, choose Universal Document Converter, then select the Properties option. When the Properties window is displayed, choose Load Settings… From the list of available settings, select PDF to JPEG.
TIFF files can store an unlimited number of separate images. Each image has an IFD, or Image File Directory, that records where that image's data and metadata is stored in the file.
Unless you want to save the individual pages to different image format, there is no point in decoding the image. Given the special structure of the TIFF image, you can split a multipage TIFF into single TIFF images without decoding.

How to append multiple images to existing single page or multi-page TIFF files. You can load as many images as you want by clicking the Load Images button. All these images will be shown in panels. Now you can click the AddtoExistingFile button. An open file dialog will open and you can specify a file name by selecting any TIFF file from ...
You need to instantiate an Image object using the Image class static method FromFile (). Then we need to determine how many pages exist in this single .TIF file by calling the Image class GetFrameCount () method and set the parameter by passing the FrameDimension.Page enumerator.
You can use the Java Advanced Imaging library, JAI, to split a mutlipage TIFF, by using an ImageReader:
ImageInputStream is = ImageIO.createImageInputStream(new File(pathToImage));
if (is == null || is.length() == 0){
// handle error
}
Iterator<ImageReader> iterator = ImageIO.getImageReaders(is);
if (iterator == null || !iterator.hasNext()) {
throw new IOException("Image file format not supported by ImageIO: " + pathToImage);
}
// We are just looking for the first reader compatible:
ImageReader reader = (ImageReader) iterator.next();
iterator = null;
reader.setInput(is);
Then you can get the number of pages:
nbPages = reader.getNumImages(true);
and read pages separatly:
reader.read(numPage)
A fast but non JAVA solution is tiffsplit. It is part of the libtiff library.
An example command to split a tiff file in all it's layers would be:
tiffsplit image.tif
The manpage says it all:
NAME
tiffsplit - split a multi-image TIFF into single-image TIFF files
SYNOPSIS
tiffsplit src.tif [ prefix ]
DESCRIPTION
tiffsplit takes a multi-directory (page) TIFF file and creates one or more single-directory (page) TIFF files
from it. The output files are given names created by concatenating a prefix, a lexically ordered suffix in the
range [aaa-zzz], the suffix .tif (e.g. xaaa.tif, xaab.tif, xzzz.tif). If a prefix is not specified on the
command line, the default prefix of x is used.
OPTIONS
None.
BUGS
Only a select set of ‘‘known tags’’ is copied when splitting.
