Tim Allison updated TIKA-4209:
------------------------------
Description:
[~johanvanderknijff] recently published a great post on multi-image TIFFs:
[https://www.bitsgalore.org/2024/03/11/multi-image-tiffs-subfiles-and-image-file-directories]
I hadn't worked on TIFF in a while. I tried out a few sample multi-image tiffs
and found that we are not processing anything beyond the first page/image in a
TIFF. Even worse, we're not populating our
"{color:#000000}imagereader:NumImages{color}" metadata value for TIFFs.
It looks like Drew Noakes' metadata-extractor is not yet handling these well:
[https://github.com/drewnoakes/metadata-extractor/issues/648]
There's an example file on that issue:
[https://github.com/drewnoakes/metadata-extractor/files/14052854/color-pages-jpg.zip]
And [~johanvanderknijff] also pointed out to TIFFs available here:
