Trejkaz updated IMAGING-127:

    Attachment: june 1 part I.tif

Sorry for the delay. I have this stuff on my home email but all the good source data was at work...

Here's a file I can redistribute. It's particularly interesting because every page has a slightly different size. Since it seems like it came from a scanner, there might be other interesting properties...

> 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.)
