Re: Browser-friendly text image compression



JBEG performs considerably better than CCITT level 4, but is not yet
a finalized standard, as far as I know. I have seen some codecs
available on the net though, but it certainly isn't supported by
browsers, or photo editing programs. CCITT level 4 is supported by
Photoshop (reading only in 5.5), and is more standard, so currently
that is what I use to store my page scans. I use the tools that
come with TiffLib to convert these pages from other Tiff incarnations.
