to no benefit, particularly for mononcrome images (unless you need to include searchable text or embed arbitrary metadata in your image file).

MUCH smaller file sizes courtesy of JBIG2! And the possibility of JPEG2000 for color images. PLUS, the ability to do "image segmentation" to use the optimal compression for each component of a multi-element page (eg. text vs. pictures on a newspaper page).

And, as you note, such (pretty) important things as searchable text and metadata.

Interestingly, as I get more into the MDI format, I'm seeing support for some of these things (I don't know if it does segmentation, but I presume it might for at least some variations based on some scant docs/papers. There are tags for equivalent text and metadata.

If only it was documented :-)
