Gary Lucas commented on IMAGING-127:
------------------------------------
I'm don't know what the level of interest is for this issue. But I do know of
an example application in the "test" hierarchy that shows one way to extract
images and metadata. It uses low-level calls and is a bit specialized for
general application work. It might help get you started on your own
implementation.

> getBufferedImage() only returns the first image. There should be a way to
> retrieve any image by index (and by extension, an API to get the image count.)
> getBufferedImages() cannot be used for large multi-page TIFF files, because
> creating that many BufferedImage objects causes an OutOfMemoryError.
> (For that matter, a method to get a scaled down copy would be useful as well,
> as some formats can optimise that not to retrieve all the data, but also it
> means you can reduce the memory usage for absolutely massive images.)
